182-620: The HAL Tejas ( Sanskrit : तेजस, ISO : Tējasa , lit.   ' Radiance ' ) is an Indian single-engine, delta wing , multirole combat aircraft designed by the Aeronautical Development Agency (ADA) and manufactured by Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF) and Indian Navy . Tejas made its first flight in 2001 and entered into service with the IAF in 2015. In 2003,

364-616: A control configured vehicle incorporating a digital FBW flight control system. Kota Harinarayana was the Programme Director and Chief Designer of Tejas. In 1992, a dedicated National Control Law (CLAW) team was set up by the National Aerospace Laboratories to develop India's own state of the art FBW flight control system for the Tejas. Initially Lockheed Martin 's consultancy was sought. But it

546-532: A radar warning receiver (RWR), integrated self-protection jammer , chaff and flare dispenser system. The upgraded variant of the Tejas Mark 1, named the Tejas Mark 1A have an AESA radar, new high performance digital flight control computer (DFCC MK1A), new EW suite and updated avionics. Some of the production Mark 1A fighters will be equipped with the Elta EL/M-2052 AESA radar, while rest of

728-466: A dead language in the most common usage of the term. Pollock's notion of the "death of Sanskrit" remains in this unclear realm between academia and public opinion when he says that "most observers would agree that, in some crucial way, Sanskrit is dead." Pokhran-II Pokhran-II ( Operation Shakti ) was a series of five nuclear weapon tests conducted by India in May 1998. The bombs were detonated at

910-553: A discussion with Abdul Kalam and Chidambaram to conduct nuclear tests. On 28 March 1998, he asked to make preparations for a test. The Indian Intelligence Bureau had been aware of the capability of the United States spy satellites in detecting Indian test preparations. Therefore, the tests required complete secrecy and the 58th Engineer Regiment of the Indian Army Corps of Engineers was tasked with preparing

1092-598: A dozen nuclear fission bombs, the deliverance mechanism was still under development. With the successful testing of Agni missile and successful trials involving dropping of similar bombs without fissionable material from bomber aircraft in 1994, the weaponization became successful. With the Comprehensive Nuclear-Test-Ban Treaty under discussion and global pressure pushing India to sign, then Indian Prime Minister Narasimha Rao ordered preparations for further nuclear tests in 1995. Based on

1274-414: A fast I/O controller based on an autonomous state machine, increased computational throughput, and sophisticated on-board software that satisfies DO-178C level-A safety regulations. All important metrics and the flight controls' performance were deemed adequate during the flying test. Developing an indigenous jet engine for Tejas was one of the five self-reliance goals identified at the beginning of

1456-553: A few years. With the return of Indira Gandhi in 1980 , the nuclear program gained momentum. Two new underground shafts were constructed at the Pokhran test range by 1982 and Gandhi approved further nuclear tests in 1982. But the decision was reversed owing to pressure from the United States as it might end-up in nuclear brinkmanship with Pakistan and potential foreign policy implications. But work continued towards weaponizing

1638-628: A flight clearance certificate for the Aircraft Mounted Accessory Gear Box (AMAGB) bearings and power take-off shaft . The Centre for Military Airworthiness and Certification (CEMILAC) also gave clearance for the pre-production of landing gear seals developed by the Combat Vehicles Research and Development Establishment (CVRDE) and Fluoro Carbon Seals Limited. In December 2006, the IAF announced that it would form an "LCA Induction Team" to manage

1820-433: A focus on Indian philosophies and Sanskrit. Though written in a number of different scripts, the dominant language of Hindu texts has been Sanskrit. It or a hybrid form of Sanskrit became the preferred language of Mahayana Buddhism scholarship; for example, one of the early and influential Buddhist philosophers, Nagarjuna (~200 CE), used Classical Sanskrit as the language for his texts. According to Renou, Sanskrit had

2002-706: A fresh RFI for the procurement of 57 multi-role carrier borne fighters. Because the technologies developed for the Tejas programme will be carried over to other platforms currently being developed by the ADA, test flying was continued. In 2019, an LCA navy prototype successfully carried out the first arrested landing at the SBTF in Goa in day time and night time. As of December 2019, the Naval LCA programme completed 209 test flights, of these 50 were ski jump take-offs. In January 2020,

2184-591: A language competed with numerous, less exact vernacular Indian languages called Prakritic languages ( prākṛta - ). The term prakrta literally means "original, natural, normal, artless", states Franklin Southworth . The relationship between Prakrit and Sanskrit is found in Indian texts dated to the 1st millennium CE. Patañjali acknowledged that Prakrit is the first language, one instinctively adopted by every child with all its imperfections and later leads to

2366-658: A limited role in the Theravada tradition (formerly known as the Hinayana) but the Prakrit works that have survived are of doubtful authenticity. Some of the canonical fragments of the early Buddhist traditions, discovered in the 20th century, suggest the early Buddhist traditions used an imperfect and reasonably good Sanskrit, sometimes with a Pali syntax, states Renou. The Mahāsāṃghika and Mahavastu, in their late Hinayana forms, used hybrid Sanskrit for their literature. Sanskrit

2548-619: A modern glass cockpit . The Autolay computer-aided design software developed as part of the LCA programme has been licensed to Airbus for its A380 wide-body aircraft project. The development of a multi-mode pulse-doppler radar was abandoned, off the shelf Israeli Elta EL/M-2032 multi-mode and EL/M-2052 Active electronically scanned array (AESA) radar units being selected for the Mk1 and initial Mk1a aircraft, respectively, while DRDO opted, in 2012, to develop its own Uttam AESA Radar , as of 2024

2730-506: A more powerful General Electric F414 INS6 engine, canards and other design changes. The Tejas Mark 2, which is expected to be rolled out in 2025, will have an increased payload carrying capacity and internal fuel capacity, more external hardpoints, improved combat range, a completely redesigned cockpit, and an integrated infrared search and track (IRST) system, in addition to the AESA radar. The Defence Institute of Advanced Technology (DIAT)

2912-454: A natural part of the earliest Vedic language, and that these developed in the centuries after the composition had been completed, and as a gradual unconscious process during the oral transmission by generations of reciters. The primary source for this argument is internal evidence of the text which betrays an instability of the phenomenon of retroflexion, with the same phrases having sandhi-induced retroflexion in some parts but not other. This

3094-406: A need-to-know basis, the pilot interacts with onboard systems through a multi-functional keyboard and several selection panels. The Tejas has a "get-you-home" panel coupled with an air data computer developed by Bharat Electronics Limited to assist the pilot in case of an emergency. The cockpit is equipped with Martin-Baker 16LG zero-zero ejection seat and canopy severance system developed by

3276-479: A negative evidence to Pollock's hypothesis, but it is not positive evidence. A closer look at Sanskrit in the Indian history after the 12th century suggests that Sanskrit survived despite the odds. According to Hanneder, On a more public level the statement that Sanskrit is a dead language is misleading, for Sanskrit is quite obviously not as dead as other dead languages and the fact that it is spoken, written and read will probably convince most people that it cannot be

3458-472: A nose droop to provide improved view for carrier landings. In addition to the elevons, the naval LCA has wing leading–edge vortex controllers (LEVCON) control surfaces that extend from the wing-root leading edge, which could be deflected to a downward angle or an upward angle to increase lift and reduce airspeed during approach. The LEVCONs also provides better low-speed handling and increase controllability at high angles of attack (AoA). The naval Tejas also has

3640-546: A pan-Indo-Aryan accessibility to information and knowledge in the ancient and medieval times, in contrast to the Prakrit languages which were understood just regionally. It created a cultural bond across the subcontinent. As local languages and dialects evolved and diversified, Sanskrit served as the common language. It connected scholars from distant parts of South Asia such as Tamil Nadu and Kashmir, states Deshpande, as well as those from different fields of studies, though there must have been differences in its pronunciation given

3822-427: A press conference to announce the tests and declared India as a full-fledged nuclear state. As a consequence of the tests, United Nations Security Council Resolution 1172 was enacted and economic sanctions were imposed by a number of countries including Japan and the United States . Efforts towards building a nuclear bomb , infrastructure, and research on related technologies have been undertaken by India since

4004-578: A refined and standardized grammatical form that emerged in the mid-1st millennium BCE and was codified in the most comprehensive of ancient grammars, the Aṣṭādhyāyī ('Eight chapters') of Pāṇini . The greatest dramatist in Sanskrit, Kālidāsa , wrote in classical Sanskrit, and the foundations of modern arithmetic were first described in classical Sanskrit. The two major Sanskrit epics, the Mahābhārata and

4186-639: A replacement for the Mikoyan-Gurevich MiG-21 , instead it is now part of a general IAF fleet modernisation programme. Prototype testing began in 2003, a year after the first flight of the second Technology Demonstrator (TD-2). The first prototype aircraft, PV-1, made its maiden flight in 2003. The first trainer prototype PV-5 was rolled out in 2009 and made its first flight on 26 November 2009. A total of two trainer prototypes were built and designated PV-5 and PV-06. The first naval prototype, designated NP-1, made its first flight on 27 April 2012. It

4368-538: A restrained language from which archaisms and unnecessary formal alternatives were excluded". The Classical form of the language simplified the sandhi rules but retained various aspects of the Vedic language, while adding rigor and flexibilities, so that it had sufficient means to express thoughts as well as being "capable of responding to the future increasing demands of an infinitely diversified literature", according to Renou. Pāṇini included numerous "optional rules" beyond

4550-439: A similar phonetic structure to Tamil. Hock et al. quoting George Hart state that there was influence of Old Tamil on Sanskrit. Hart compared Old Tamil and Classical Sanskrit to arrive at a conclusion that there was a common language from which these features both derived – "that both Tamil and Sanskrit derived their shared conventions, metres, and techniques from a common source, for it is clear that neither borrowed directly from

4732-467: A statement condemning India and threatened economic sanctions . The intelligence community felt humiliated for its failure to detect the preparations for the test. In keeping with its preferred approach to foreign policy in recent decades , and in compliance with the 1994 anti-proliferation law , the United States imposed economic sanctions on India. The sanctions on India consisted of cutting off all assistance to India except humanitarian aid, banning

4914-585: A strengthened undercarriage, stronger landing gear, and an arrestor hook system for carrier landings. The two-seat LCA Navy variant (NP-1) have aerodynamic commonality with the trainer variant. The Secondary Flight Control of Tejas Mk 1A consists of an indigenously designed Leading Edge Slats and Airbrake Control Module. Aeronautical Development Agency , on 19 April 2024, delivered the first batch of these flight control system. These flight control systems features "state-of-the-art Servo-Valve based electro-hydraulic servo actuators and control modules." The technology

5096-711: Is a classical language belonging to the Indo-Aryan branch of the Indo-European languages . It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age . Sanskrit is the sacred language of Hinduism , the language of classical Hindu philosophy , and of historical texts of Buddhism and Jainism . It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in

5278-418: Is a single-engine multirole combat aircraft which has a tailless, compound delta wing design with "relaxed static stability" for enhanced manoeuvrability and agility. The Tejas is a multi-role combat aircraft and its flexibility permits it to carry out Interception , air-to-surface and anti-shipping roles in a single mission. The wind tunnel testing and computational fluid dynamics analysis have optimised

5460-516: Is akin to that of Latin and Ancient Greek in Europe. Sanskrit has significantly influenced most modern languages of the Indian subcontinent , particularly the languages of the northern, western, central and eastern Indian subcontinent. Sanskrit declined starting about and after the 13th century. This coincides with the beginning of Islamic invasions of South Asia to create, and thereafter expand

5642-466: Is based on a delta-wing layout with shoulder-mounted wings. The control surfaces include three-section slats on the wing's outer leading edge while the inboard sections of the wings have additional slats to generate vortex lift over the inner wing and high-energy air-flow along the tail fin to enhance high-AoA stability. The wing trailing edge fits two-segment elevons to provide pitch and roll control . The only empennage -mounted control surfaces are

5824-457: Is being developed for the Tejas. The relatively smaller size, extensive use of airframe composites, the Y-duct inlet which shields the engine compressor blades, the application of radar-absorbent material (RAM) coatings and so on, reduces the overall radar cross-section of the aircraft. Apart from aluminium-lithium alloys and titanium alloys , carbon-fibre composite materials are used in

6006-629: Is currently powered by the F404-IN20 engine. The Mark 1A variant will be powered by the same powerplant, while the heavier Tejas Mark 2 will be powered by a General Electric F414 -INS6 engine. On 17 August 2021, HAL placed an order of ₹ 5,375 crore (equivalent to ₹ 60 billion or US$ 720 million in 2023) for 99 F404-GE-IN20 engines. Sanskrit Sanskrit ( / ˈ s æ n s k r ɪ t / ; attributively 𑀲𑀁𑀲𑁆𑀓𑀾𑀢𑀁 , संस्कृत- , saṃskṛta- ; nominally संस्कृतम् , saṃskṛtam , IPA: [ˈsɐ̃skr̩tɐm] )

6188-467: Is developing aircraft health and usage monitoring systems (HUMS) to integrate the various sensors on board the Tejas Mark 2. The first flight of Tejas Mark 2 is expected to be in 2025. The Naval LCA programme was commenced in 2003. According to ADA, the Naval LCA (N-LCA) Programme was envisaged to be completed in two phases, under Phase-1 two naval prototypes were developed - the two-seat NP-1 and

6370-452: Is found in the writing of Bharata Muni , the author of the ancient Natya Shastra text. The early Jain scholar Namisādhu acknowledged the difference, but disagreed that the Prakrit language was a corruption of Sanskrit. Namisādhu stated that the Prakrit language was the pūrvam ('came before, origin') and that it came naturally to children, while Sanskrit was a refinement of Prakrit through "purification by grammar". Sanskrit belongs to

6552-532: Is rare in the later version of the language. The Homerian Greek, like Ṛg-vedic Sanskrit, deploys simile extensively, but they are structurally very different. The early Vedic form of the Sanskrit language was far less homogenous compared to the Classical Sanskrit as defined by grammarians by about the mid-1st millennium BCE. According to Richard Gombrich—an Indologist and a scholar of Sanskrit, Pāli and Buddhist Studies—the archaic Vedic Sanskrit found in

6734-462: Is ready to be integrated with production variants of Tejas Mk 1A as it successfully completed flight trials. These are being produced at Accessories Division, HAL, Lucknow . The avionics of the Tejas Mark 1 is centered around Elta EL/M-2032 radar. Its digital flight control computer developed by ADE and manufactured BEL. It has an electronic warfare (EW) suite domestically developed by Defence Avionics Research Establishment (DARE), which consists of

6916-479: Is taken along with evidence of controversy, for example, in passages of the Aitareya-Āraṇyaka (700 BCE), which features a discussion on whether retroflexion is valid in particular cases. The Ṛg-veda is a collection of books, created by multiple authors. These authors represented different generations, and the mandalas 2 to 7 are the oldest while the mandalas 1 and 10 are relatively the youngest. Yet,

7098-589: Is the predominant language of one of the largest collection of historic manuscripts. The earliest known inscriptions in Sanskrit are from the 1st century BCE, such as the Ayodhya Inscription of Dhana and Ghosundi-Hathibada (Chittorgarh) . Though developed and nurtured by scholars of orthodox schools of Hinduism, Sanskrit has been the language for some of the key literary works and theology of heterodox schools of Indian philosophies such as Buddhism and Jainism. The structure and capabilities of

7280-540: The Bhagavata Purana , the Panchatantra and many other texts are all in the Sanskrit language. The Classical Sanskrit with its exacting grammar was thus the language of the Indian scholars and the educated classes, while others communicated with approximate or ungrammatical variants of it as well as other natural Indian languages. Sanskrit, as the learned language of Ancient India, thus existed alongside

7462-580: The Dalai Lama , the Sanskrit language is a parent language that is at the foundation of many modern languages of India and the one that promoted Indian thought to other distant countries. In Tibetan Buddhism, states the Dalai Lama, Sanskrit language has been a revered one and called legjar lhai-ka or "elegant language of the gods". It has been the means of transmitting the "profound wisdom of Buddhist philosophy" to Tibet. The Sanskrit language created

7644-525: The Fly-by-wire (FBW) flight control system, multi-mode pulse-doppler radar , and afterburning turbofan engine . The project definition phase was commenced in October 1986 with France's Dassault-Breguet Aviation as consultant. Dassault-Breguet's expertise was mainly utilised in the design and system integration of the Tejas. In 1988, Dassault offered a hybrid fly by wire flight control system for

7826-653: The Indian Army 's Pokhran Test Range in Rajasthan . It was the second instance of nuclear testing conducted by India, after the first test, code-named Smiling Buddha , was conducted in May 1974. The test consisted of five detonations, the first of which was a high yield fusion bomb while the remaining four were fission bombs . One fusion and two fission bombs were detonated on 11 May 1998 and two more fission bombs were detonated two days later on 13 May 1998. The tests were collectively called Operation Shakti , and

8008-613: The Indo-European family of languages . It is one of the three earliest ancient documented languages that arose from a common root language now referred to as Proto-Indo-European : Other Indo-European languages distantly related to Sanskrit include archaic and Classical Latin ( c. 600 BCE–100 CE, Italic languages ), Gothic (archaic Germanic language , c.  350 CE ), Old Norse ( c. 200 CE and after), Old Avestan ( c.  late 2nd millennium BCE ) and Younger Avestan ( c. 900 BCE). The closest ancient relatives of Vedic Sanskrit in

8190-591: The Indo-Pakistani War , the U.S. government sent a carrier battle group into the Bay of Bengal in an attempt to intimidate India, who were aided by the Soviet Union , who responded by sending a submarine armed with nuclear missiles . The Soviet response demonstrated the deterrent value and significance of nuclear weapons to India. After India gained military and political initiative over Pakistan in

8372-729: The Insurgency in Jammu and Kashmir . During this time, the Indian Missile Program succeeded in the development of the Prithvi missiles . India decided to observe the temporary moratorium on the nuclear tests for fear of inviting international criticism. The NSG decided in 1992 to require full-scope IAEA safeguards for any new nuclear export deals, which effectively ruled out nuclear exports to India. Though India had stock-piled material and components to be able to construct

8554-661: The R-73 and Python-5 close combat missiles, the I-Derby ER beyond visual range air-to-air missile and guided–unguided munition releases. The LSPs were also used for sensor trials involving integration and testing of the Israeli Elta EL/M-2032 multi-mode radar, and EL/M-2052 AESA radar, and the Indian Uttam AESA Radar and Rafael Litening targeting pod. The Uttam radar was integrated on

8736-753: The Rigveda had already evolved in the Vedic period, as evidenced in the later Vedic literature. Gombrich posits that the language in the early Upanishads of Hinduism and the late Vedic literature approaches Classical Sanskrit, while the archaic Vedic Sanskrit had by the Buddha 's time become unintelligible to all except ancient Indian sages. The formalization of the Saṃskṛta language is credited to Pāṇini , along with Patañjali's Mahābhāṣya and Katyayana's commentary that preceded Patañjali's work. Panini composed Aṣṭādhyāyī ('Eight-Chapter Grammar'), which became

8918-532: The Rigveda , a collection of 1,028 hymns composed between 1500 BCE and 1200 BCE by Indo-Aryan tribes migrating east from the mountains of what is today northern Afghanistan across northern Pakistan and into northwestern India. Vedic Sanskrit interacted with the preexisting ancient languages of the subcontinent, absorbing names of newly encountered plants and animals; in addition, the ancient Dravidian languages influenced Sanskrit's phonology and syntax. Sanskrit can also more narrowly refer to Classical Sanskrit ,

9100-531: The Rāmāyaṇa , however, were composed in a range of oral storytelling registers called Epic Sanskrit which was used in northern India between 400 BCE and 300 CE, and roughly contemporary with classical Sanskrit. In the following centuries, Sanskrit became tradition-bound, stopped being learned as a first language, and ultimately stopped developing as a living language. The hymns of the Rigveda are notably similar to

9282-558: The UN Security Council adopted Resolution 1172 , condemning the Indian and Pakistani tests. The Government of India declared 11 May as National Technology Day in India to commemorate the first of the five successful nuclear weapon tests that were carried out on 11 May 1998. The day is celebrated by giving awards to various individuals and industries in the field of science and technology. Parmanu: The Story of Pokhran

9464-498: The collapse of the government , the program continued under M.R. Srinivasan , but made slow progress. Though the nuclear program did not receive much attention from incoming Prime Minister Morarji Desai at first, the program gained impetus when Ramanna was appointed to the Ministry of Defence . With the discovery of Pakistan's clandestine atomic bomb program , India realized that it was very likely to succeed in its project in

9646-406: The sandhi rules, both internal and external. Quite many words found in the early Vedic Sanskrit language are never found in late Vedic Sanskrit or Classical Sanskrit literature, while some words have different and new meanings in Classical Sanskrit when contextually compared to the early Vedic Sanskrit literature. Arthur Macdonell was among the early colonial era scholars who summarized some of

9828-500: The verbal adjective sáṃskṛta- is a compound word consisting of sáṃ ('together, good, well, perfected') and kṛta - ('made, formed, work'). It connotes a work that has been "well prepared, pure and perfect, polished, sacred". According to Biderman, the perfection contextually being referred to in the etymological origins of the word is its tonal—rather than semantic—qualities. Sound and oral transmission were highly valued qualities in ancient India, and its sages refined

10010-401: The yield was estimated to be between 6 and 10 kilotons . Premiership [REDACTED] While India continued to state that the test was for peaceful purposes, it encountered opposition from many countries. The Nuclear Suppliers Group (NSG) was formed in reaction to the Indian tests to check international nuclear proliferation . The technological embargo and sanctions affected

10192-414: The 13th century, a premier center of Sanskrit literary creativity, Sanskrit literature there disappeared, perhaps in the "fires that periodically engulfed the capital of Kashmir" or the "Mongol invasion of 1320" states Pollock. The Sanskrit literature which was once widely disseminated out of the northwest regions of the subcontinent, stopped after the 12th century. As Hindu kingdoms fell in the eastern and

10374-532: The 7th century where he established a major center of learning and language translation under the patronage of Emperor Taizong. By the early 1st millennium CE, Sanskrit had spread Buddhist and Hindu ideas to Southeast Asia, parts of the East Asia and the Central Asia. It was accepted as a language of high culture and the preferred language by some of the local ruling elites in these regions. According to

The Tejas has an integrated health-monitoring system. The Tejas has a night vision goggles compatible glass cockpit, equipped with a domestically developed head-up display (HUD), three multi-function displays, two Smart Standby Displays by Central Scientific Instruments Organization (CSIO). The Tejas has hands-on-throttle-and-stick (HOTAS) arrangement to reduce pilot's workload. The displays provide key information on

10920-425: The Classical Sanskrit language launched ancient Indian speculations about "the nature and function of language", what is the relationship between words and their meanings in the context of a community of speakers, whether this relationship is objective or subjective, discovered or is created, how individuals learn and relate to the world around them through language, and about the limits of language? They speculated on

11102-462: The DRDO for safe ejection. For life support, Tejas Mark 1 relies on conventional liquid oxygen LOX system, while an onboard oxygen-generation system (OBOGS) has been developed for Tejas Mark 1A. The ADA has developed virtual reality assisted cockpit simulator for Tejas, and N-LCA. Currently Tejas pilots are flying with Elbit DASH IV helmet-mounted display system.

11284-532: The Dravidian languages borrowed from Sanskrit vocabulary, but they have also affected Sanskrit on deeper levels of structure, "for instance in the domain of phonology where Indo-Aryan retroflexes have been attributed to Dravidian influence". Similarly, Ferenc Ruzca states that all the major shifts in Indo-Aryan phonetics over two millennia can be attributed to the constant influence of a Dravidian language with

Shulman mentions that "Dravidian nonfinite verbal forms (called vinaiyeccam in Tamil) shaped the usage of the Sanskrit nonfinite verbs (originally derived from inflected forms of action nouns in Vedic). This particularly salient case of

The Tejas can also carry pod-based sensors such as forward looking infrared (FLIR). Currently the Tejas is cleared to carry the Rafael Litening III targeting/reconnaissance pod, while an advanced version named Litening 4I will be integrated on the Tejas. The Litening 4I pod, developed by

In May 2015, the Comptroller and Auditor General of India (CAG) noted some shortcomings in the then-delivered Tejas Mark 1 IOC standard aircraft, which according to the CAG would limit the ability to survive and operation deployment of

12012-594: The FOC certificate to the then Air Chief Marshal BS Dhanoa at the Yelahanka Air Force base. After the formal ceremoney, ACM Dhanoa stated that Tejas was "ready" and "behaved like a true fighter" . The second Tejas squadron – No.18 Flying Bullets was formed at Sulur Air Force Station on 27 May 2020 with the first four serial production FOC aircraft. A full mission simulator (FMS) phase-1 was commissioned at Sulur Air Force Station on 23 October 2021. Phase 1 of

12194-462: The Government of India established Aeronautical Development Agency (ADA) under the aegis of Defence Research and Development Organisation (DRDO) to manage the LCA programme. The ADA was entrusted with the design and development of LCA while HAL was chosen as the principal contractor. The government's "self-reliance" goals for the LCA included the three most sophisticated and challenging systems:

12376-476: The Indo-Aryan language underwent rapid linguistic change and morphed into the Vedic Sanskrit language. The pre-Classical form of Sanskrit is known as Vedic Sanskrit . The earliest attested Sanskrit text is the Rigveda , a Hindu scripture from the mid- to late-second millennium BCE. No written records from such an early period survive, if any ever existed, but scholars are generally confident that

12558-519: The Indo-European languages are the Nuristani languages found in the remote Hindu Kush region of northeastern Afghanistan and northwestern Himalayas, as well as the extinct Avestan and Old Persian – both are Iranian languages . Sanskrit belongs to the satem group of the Indo-European languages. Colonial era scholars familiar with Latin and Greek were struck by the resemblance of

12740-954: The LCA Programme. A programme led by the Gas Turbine Research Establishment (GTRE) to design and develop an indigenous powerplant, the Kaveri , was launched as early as in 1986. However Kaveri jet engine development faced some setbacks, hence the General Electric F404-GE-F2J3 afterburning turbofan engine was procured as an interim solution. The F404-F2J3 (10 units) powers the Technology Demonstrator and Prototype variants of Tejas. Since 2004, uprated General Electric F404-GE-IN20 engines are being used on LSP, Naval prototypes and Mark 1 variants of Tejas. The Tejas Mark 1

12922-409: The LCA, consisting of three digital channels and one analogue channel, with a redundant analogue channel as a back up in case the digital channels fails. But the ADA was in favour of a quadruplex digital FBW flight control system. The design of the Tejas was finalised in 1990 as a small tailless compound delta wing design with relaxed static stability . To provide enhanced manoeuvrability it would be

13104-509: The LRDE's advanced signal processor module. Using an "off-the-shelf" foreign radar as an interim option was considered. ADA met with success in the development of three of the five key technologies identified at the beginning of the LCA programme. The successful endeavours were mastery in the FBW flight control system, the development and manufacturing of carbon-fibre composite structures and skins, and

13286-879: The Mark 1 variant. Upgraded Mark 1A features a new avionic suite centred on EL/M-2052 AESA Radar and Uttam AESA Radar developed in-house. DARE Unified Electronic Warfare Suite (UEWS), an externally mounted self protection jammer (SPJ) for enhanced survivability, in-flight refuelling capability, Onboard Oxygen Generation System (OBOGS) developed by Defence Bioengineering and Electromedical Laboratory (DEBEL) for endurance and an expanded weapon suite consisting of Astra BVRAAM and ASRAAM .

HAL will install in-house developed Combined Interrogator and Transponder (CIT) with digital map generator by Mission and Combat Systems R&D Centre which helps transfer

13468-467: The MiG-21 variants, which had been the mainstay of the IAF since 1963. At one point the IAF had operated as many as 874 MiG-21s . The "Long Term Re-Equipment Plan 1981" noted that most of these IAF fighters were approaching the end of their service lives by the early-1990s, and that by 1995, the IAF would be 40 percent short of the aircraft needed to fill its projected force structure requirements. In 1984,

13650-532: The Muslim rule in the form of Sultanates, and later the Mughal Empire . Sheldon Pollock characterises the decline of Sanskrit as a long-term "cultural, social, and political change". He dismisses the idea that Sanskrit declined due to "struggle with barbarous invaders", and emphasises factors such as the increasing attractiveness of vernacular language for literary expression. With the fall of Kashmir around

13832-496: The Muslim rulers. Hindu rulers such as Shivaji of the Maratha Empire , reversed the process, by re-adopting Sanskrit and re-asserting their socio-linguistic identity. After Islamic rule disintegrated in South Asia and the colonial rule era began, Sanskrit re-emerged but in the form of a "ghostly existence" in regions such as Bengal. This decline was the result of "political institutions and civic ethos" that did not support

14014-473: The Prime Minister in 1984, supported technological development and research, he was skeptical about nuclear testing as he believed it would result in further technological alienation from the developed countries. Dhruva , a new reactor with a capability to produce larger quantities of weapon grade material, was commissioned at BARC in 1985. Other components for a nuclear fusion bomb were developed during

14196-499: The Saṃskṛta language, both in its vocabulary and grammar, to the classical languages of Europe. In The Oxford Introduction to Proto-Indo-European and the Proto-Indo-European World , Mallory and Adams illustrate the resemblance with the following examples of cognate forms (with the addition of Old English for further comparison): The correspondences suggest some common root, and historical links between some of

14378-638: The South India, such as the great Vijayanagara Empire , so did Sanskrit. There were exceptions and short periods of imperial support for Sanskrit, mostly concentrated during the reign of the tolerant Mughal emperor Akbar . Muslim rulers patronized the Middle Eastern language and scripts found in Persia and Arabia, and the Indians linguistically adapted to this Persianization to gain employment with

14560-608: The TD-1 successfully flew with an indigenous quadruplex digital FBW flight control system. The aerodynamic characterization research was conducted at the National Aerospace Laboratories' 1.2m Trisonic Wind Tunnel Facility. Another critical technology needed for LCA was the multi-mode radar (MMR). Initially, the Ericsson / Ferranti PS-05/A I/J-band multi-function radar, also used on Saab 's JAS 39 Gripen ,

14742-654: The Tejas LSP-2 and LSP-3, and logged about 30 hours of flight testing on the Tejas alone. The high altitude trials and hot weather trials were carried out with the LSPs and the PV-3 prototype, in IOC and FOC configurations. These trials were mainly focused on assessing the performance of the various sensors and avionics on board, at temperatures ranging from below -10 degree Celsius to more than +45 degrees Celsius. Sea trials to assess

14924-608: The Tejas Mark 2. An agreement has been signed by the Indian Air Force and the Aeronautical Development Agency to include advanced weaponry and sensors into HAL Tejas. By transferring technical know-how for the smooth integration of weapons and sensors, ADA and the IAF's Software Development Institute (SDI) hope to empower the IAF to carry out integration and flight testing on its own. The Tejas Mark 1A variant has more than 40 improvements over

15106-516: The Uttam radar is undergoing flight trials. India's self-reliance goal oriented development for the LCA programme has considerably increased the indigenous components in Tejas and contributed to an aviation industry expansion in the country. On 20 December 2021, Ministry of Defence (MoD) in a written reply during winter session of Rajya Sabha clarified that the HAL Tejas is no longer considered as

15288-447: The Vedic Sanskrit in these books of the Ṛg-veda "hardly presents any dialectical diversity", states Louis Renou – an Indologist known for his scholarship of the Sanskrit literature and the Ṛg-veda in particular. According to Renou, this implies that the Vedic Sanskrit language had a "set linguistic pattern" by the second half of the 2nd millennium BCE. Beyond the Ṛg-veda, the ancient literature in Vedic Sanskrit that has survived into

15470-451: The Vedic Sanskrit's bahulam framework, to respect liberty and creativity so that individual writers separated by geography or time would have the choice to express facts and their views in their own way, where tradition followed competitive forms of the Sanskrit language. The phonetic differences between Vedic Sanskrit and Classical Sanskrit, as discerned from the current state of the surviving literature, are negligible when compared to

15652-555: The afternoon. Santhanam, in-charge of the test site, handed over the site to M. Vasudev, the range safety officer, who was responsible for verifying the test indicators. After the safety clearance, the countdown system was activated and at 3:45 PM IST , the three devices were detonated simultaneously. On 13 May, at 12.21 PM IST, two sub-kiloton devices ( Shakti IV and V ) were detonated. Due to their very low yield, these explosions were not detected by any seismic station. Having tested weaponized nuclear warheads, India became

15834-511: The aircraft are expected to fly with the domestically developed Uttam AESA radar. The new EW system for the Mark 1A, developed by DARE known as the Unified Electronic Warfare suite (UEWS), will have electronic countermeasures and electronic counter-countermeasure capabilities, digital radio frequency memory based jamming and deception capabilities. The Tejas Mark 1A will also carry a pod-mounted self-protection jammer –

16016-472: The aircraft in actual combat. A few of these shortcomings, including lack of combat endurance , were addressed in the Tejas Mark 1 FOC configuration aircraft. Tejas Mark 1 FOC is modified to perform in-flight refuelling from Ilyushin Il-78 and Sukhoi Su-30MKI . Tejas is also undergoing butt firing trials and air-to-air firing at HAL, Nashik facility with Gryazev-Shipunov GSh-23 . The shortcomings, such as

16198-470: The aircraft was officially named 'Tejas '. Currently Tejas is the smallest and lightest in its class of supersonic combat aircraft. Tejas is the second supersonic combat aircraft developed by HAL after the HF-24 Marut . The first Tejas squadron became operational in 2016. The No. 45 Squadron IAF - Flying Daggers, based at Sulur Air Force Station (AFS) in the southern Indian state of Tamil Nadu,

16380-754: The aircraft's service introduction. The Tejas was awarded initial operational clearance-I (IOC-I) in January 2011. To ease up the process of FOC, an interim IOC-II was issued to Tejas in December 2013. The IOC-II expanded the g-limit, angle of attack and allowed the aircraft to carry precision guided munitions and close combat missiles. The IOC-II Tejas have an operational radius of 400–500 km (250–310 mi). The first squadron, consisting of Tejas in IOC-II configuration, became operational in 2016. The No. 45 Squadron IAF based at Sulur Air Force Station , Coimbatore

16562-407: The alphabet, the structure of words, and its exacting grammar into a "collection of sounds, a kind of sublime musical mold" as an integral language they called Saṃskṛta . From the late Vedic period onwards, state Annette Wilke and Oliver Moebus, resonating sound and its musical foundations attracted an "exceptionally large amount of linguistic, philosophical and religious literature" in India. Sound

16744-464: The bombs, including the detonators , the implosion and high-voltage trigger systems. These were also responsible for systems engineering, aerodynamics and safety. The bombs were transported moved from BARC at 3 am on 1 May 1998 to Bombay airport , then flown in an Indian Air Force 's AN-32 aircraft to Jaisalmer Airport . It was then transported to Pokhran in an army convoy of four trucks, and this required three trips. The devices were delivered to

16926-440: The capacity to understand the old Prakrit languages such as Ardhamagadhi . A section of European scholars state that Sanskrit was never a spoken language. However, evidences shows that Sanskrit was a spoken language, essential for oral tradition that preserved the vast number of Sanskrit manuscripts from ancient India. The textual evidence in the works of Yaksa, Panini, and Patanajali affirms that Classical Sanskrit in their era

17108-463: The centreline pylon and inboard pairs of wing stations. It has an aerial refuelling probe on the starboard side of the forward fuselage. The Tejas weapon suite consists of I-Derby ER and Astra beyond visual range air-to-air missiles and R-73, Python-5 and ASRAAM close combat missiles. The Tejas has an internal 23 mm Gryazev-Shipunov GSh-23 twin-barreled autocannon under the starboard side air-intake. The BrahMos-NG supersonic cruise missile

17290-527: The close relationship between the Indo-Iranian tongues and the Baltic and Slavic languages , vocabulary exchange with the non-Indo-European Uralic languages , and the nature of the attested Indo-European words for flora and fauna. The pre-history of Indo-Aryan languages which preceded Vedic Sanskrit is unclear and various hypotheses place it over a fairly wide limit. According to Thomas Burrow, based on

17472-461: The construction of the Tejas. The composite materials constitute 45% of the airframe by weight and 90% by surface area, the highest among contemporary aircraft. The upper and lower wing surfaces, wing spars and wing ribs are also made out of carbon-fibre composites, while the fin tip is made out of fiberglass . The extensive use of composite materials in the airframe not only makes the aircraft lighter but also gives high strength. This also reduces

17654-614: The context of a speech or language, is found in verses 5.28.17–19 of the Ramayana . Outside the learned sphere of written Classical Sanskrit, vernacular colloquial dialects ( Prakrits ) continued to evolve. Sanskrit co-existed with numerous other Prakrit languages of ancient India. The Prakrit languages of India also have ancient roots and some Sanskrit scholars have called these Apabhramsa , literally 'spoiled'. The Vedic literature includes words whose phonetic equivalent are not found in other Indo-European languages but which are found in

17836-528: The country had a total of $ 44bn in loans in 1998, from the IMF and the World Bank . The industrial sectors of the Indian economy were likely to be hurt by sanctions with the foreign companies, which had invested heavily in India, facing consequences of impending sanctions. The Indian government announced that it had factored the economic response and was willing to take the consequences. The United States issued

18018-653: The crystallization of Classical Sanskrit. As in this period the Indo-Aryan tribes had not yet made contact with the inhabitants of the South of the subcontinent, this suggests a significant presence of Dravidian speakers in North India (the central Gangetic plain and the classical Madhyadeśa) who were instrumental in this substratal influence on Sanskrit. Extant manuscripts in Sanskrit number over 30 million, one hundred times those in Greek and Latin combined, constituting

18200-543: The current fleet of MIG-29K/KUB carrier-based fighters. In Aero India 2021 a new twin engine naval fighter was unveiled, the Twin Engine Deck Based Fighter (TEDBF). The experience gained in the N-LCA programme will help in the development of TEDBF. In February 2023, the naval prototype completed its maiden landing and take-off from the indigenous aircraft carrier INS  Vikrant . The Tejas

18382-486: The design of Tejas for minimum transonic and supersonic wave drag , as well low wing-loading . Tejas has eight hardpoints – one beneath the port-side air-intake , one under the fuselage (centreline station) and three hardpoints under each wing, of these, three are wet hardpoints which can carry drop tanks. The hardpoint beneath the port side air-intake is dedicated to carrying sensor pods such as FLIR , IRST or laser rangefinder/designator . These can also be carried on

18564-467: The detailed and sophisticated treatise then transmitted it through his students. Modern scholarship generally accepts that he knew of a form of writing, based on references to words such as Lipi ('script') and lipikara ('scribe') in section 3.2 of the Aṣṭādhyāyī . The Classical Sanskrit language formalized by Pāṇini, states Renou, is "not an impoverished language", rather it is "a controlled and

18746-546: The detonation process with all personnel required to wear uniforms to preserve the secrecy of the tests. They were given pseudo-names and they traveled in smaller groups to avoid detection. Scientists and engineers of BARC, the Atomic Minerals Directorate for Exploration and Research (AMDER) , and DRDO were involved in the development and assembly of the bombs. Three laboratories of the DRDO were involved in designing, testing and producing components for

18928-504: The development of India's nuclear program. It was crippled by the lack of indigenous resources and dependence on imported technology on certain areas. Though India declared to the International Atomic Energy Agency (IAEA) that India's nuclear program was intended only for peaceful purposes, preliminary work on a fusion bomb was initiated. In the aftermath of the state emergency in 1975 that resulted in

19110-425: The device preparation building, which was designated as Prayer Hall'. Following were the main personnel involved in the testing: The test was organized into two groups to be fired separately, with all devices in a group fired at the same time. Five nuclear devices were tested during the operation. Group-I: Group-II: An additional, sixth device ( Shakti VI ) was developed but not detonated. The first test

19292-471: The differences between the Vedic and Classical Sanskrit. Louis Renou published in 1956, in French, a more extensive discussion of the similarities, the differences and the evolution of the Vedic Sanskrit within the Vedic period and then to the Classical Sanskrit along with his views on the history. This work has been translated by Jagbans Balbir. The earliest known use of the word Saṃskṛta (Sanskrit), in

19474-457: The digital flight control computer. The fly-by-wire flight control system of the Tejas has an advanced feature called auto low-speed recovery. This enables envelope protection at low speed and high angles of attack. It prevents the aircraft from entering into uncontrolled flight while maneuvering. Another feature is disorientation recovery function , once engaged it will recover the aircraft to an optimal altitude, airspeed and level flight. Some of

19656-440: The direction of the director of DAE R. Chidambaram , S. K. Sikka was tasked with the development of a thermo-nuclear fusion device. In August, K. Santhanam , the chief technical adviser of DRDO, was appointed the director for carrying out the tests. While water was being pumped out of the shafts constructed more than ten years earlier, American spy satellites picked up the signs. With pressure from US President Bill Clinton ,

19838-460: The distant major ancient languages of the world. The Indo-Aryan migrations theory explains the common features shared by Sanskrit and other Indo-European languages by proposing that the original speakers of what became Sanskrit arrived in South Asia from a region of common origin, somewhere north-west of the Indus region , during the early 2nd millennium BCE. Evidence for such a theory includes

20020-490: The early medieval era, it became a language of religion and high culture , and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in

20202-637: The end of Second World War . The origins of India's nuclear program can be traced back to 1945 when nuclear physicist Homi Bhabha established the Tata Institute of Fundamental Research (TIFR) with the aid of Tata Group . After Indian Independence , the Atomic Energy Act was passed on 15 April 1948, that established the Indian Atomic Energy Commission (IAEC). In 1954, Department of Atomic Energy (DAE)

20384-511: The export of certain defense material and technologies, ending American credit and credit guarantees to India, and requiring the US to oppose lending by international financial institutions to India. The United States held talks with India over the issue of India becoming a part of the CTBT and NPT and pressurized to rollback India's nuclear program. India did not accede to the request stating that it

20566-548: The first language of the respective speakers. The Sanskrit language brought Indo-Aryan speaking people together, particularly its elite scholars. Some of these scholars of Indian history regionally produced vernacularized Sanskrit to reach wider audiences, as evidenced by texts discovered in Rajasthan, Gujarat, and Maharashtra. Once the audience became familiar with the easier to understand vernacularized version of Sanskrit, those interested could graduate from colloquial Sanskrit to

20748-452: The first set of Carbon-BMI Engine Bay Door assembly, successfully completed the inaugural flight from HAL facility. On 19 April 2024, ADA delivered the first batch of Secondary Flight Control of Tejas Mk 1A which consists of an indigenously designed Leading Edge Slats and Airbrake Control Module. These flight control systems features "state-of-the-art Servo-Valve based electro-hydraulic servo actuators and control modules." These development

20930-435: The five nuclear bombs were designated as Shakti-I through to Shakti-V . The tests achieved their main objective of giving India the capability to build fission and thermonuclear weapons with yields up to 200 kilotons . Then chairman of the Indian Atomic Energy Commission described each one of the explosions to be equivalent to several tests carried out over the years by various nations. The Indian government convened

21112-460: The flight control laws for these features were formulated by the IIT Bombay research university. On 19 February 2024, Tejas Mark-1A prototype LSP-7 successfully completed sortie with indigenously designed high performance Digital Flight Control Computer (DFCC). The system was developed by Aeronautical Development Establishment (ADE). The latest DFCC has a quadraplex PowerPC -based processor,

21294-617: The forces generated during carrier take off and arrested recovery. In December 2014, the LCA Navy successfully made its first ski-jump assisted take off from a SBTF at INS  Hansa . The navy variant has a distinctive flight control law mode which allows hands-free take-off. In December 2016, the Indian Navy (IN) opted out of the programme, owing to the long delay and technical reasons – such as inadequate thrust to weight ratio of N-LCA for carrier based combat operations, and issued

21476-412: The foundation of Vyākaraṇa, a Vedānga . The Aṣṭādhyāyī was not the first description of Sanskrit grammar, but it is the earliest that has survived in full, and the culmination of a long grammatical tradition that Fortson says, is "one of the intellectual wonders of the ancient world". Pāṇini cites ten scholars on the phonological and grammatical aspects of the Sanskrit language before him, as well as

21658-537: The gods Varuna, Mitra, Indra, and Nasatya found in the earliest layers of the Vedic literature. O Bṛhaspati, when in giving names they first set forth the beginning of Language, Their most excellent and spotless secret was laid bare through love, When the wise ones formed Language with their mind, purifying it like grain with a winnowing fan, Then friends knew friendships – an auspicious mark placed on their language. — Rigveda 10.71.1–4 Translated by Roger Woodard The Vedic Sanskrit found in

21840-486: The government for its decision and advocated the development of an operational nuclear arsenal for the country's armed forces. The opposition led by Indian National Congress criticized the Vajpayee administration for carrying out the series of nuclear tests, accusing the government of trying to use the tests for political ends rather than to enhance the country's national security. By the time India had conducted tests,

22022-505: The head of the nuclear programme and the direction of the programme changed towards utilizing nuclear energy peaceful purposes rather than military development. After Shastri's death in 1966, Indira Gandhi became the prime minister and work on the nuclear programme resumed. The design work on the bomb proceeded under physicist Raja Ramanna , who continued the nuclear weapons technology research after Bhabha's death in 1966. The project employed 75 scientists and progressed in secrecy. During

22204-431: The historic Sanskrit literary culture and the failure of new Sanskrit literature to assimilate into the changing cultural and political environment. Sheldon Pollock states that in some crucial way, "Sanskrit is dead ". After the 12th century, the Sanskrit literary works were reduced to "reinscription and restatements" of ideas already explored, and any creativity was restricted to hymns and verses. This contrasted with

22386-518: The increased weight and reduced speed, would be addressed in the upcoming Tejas Mark 1A aircraft by increasing the use of composites in manufacturing and reducing the supersonic drag by using more aerodynamic pylons. The MK1A will also have AESA radar, a self-protection jammer, updated avionics and electronic warfare capabilities, among other improvements. The shortcomings identified by CAG that require redesign and structural modification such as increasing internal fuel capacity, are planned to be rectified in

22568-482: The indigenous content in the Tejas Mark 1 is 59.7% by value and 75.5% by the number of line replaceable units . The indigenous content of the Tejas Mk 1A is expected to surpass 70% in the next four years. The LCA programme originated in the early 1980s. In 1983, the Government of India established the LCA project with the initial goal to develop a new light combat aircraft to replace the ageing IAF fighters, especially

22750-486: The intense change that must have occurred in the pre-Vedic period between the Proto-Indo-Aryan language and Vedic Sanskrit. The noticeable differences between the Vedic and the Classical Sanskrit include the much-expanded grammar and grammatical categories as well as the differences in the accent, the semantics and the syntax. There are also some differences between how some of the nouns and verbs end, as well as

22932-432: The largest cultural heritage that any civilization has produced prior to the invention of the printing press. — Foreword of Sanskrit Computational Linguistics (2009), Gérard Huet, Amba Kulkarni and Peter Scharf Sanskrit has been the predominant language of Hindu texts encompassing a rich tradition of philosophical and religious texts, as well as poetry, music, drama , scientific , technical and others. It

23114-412: The linguistic expression and sets the standard for the Sanskrit language. Pāṇini made use of a technical metalanguage consisting of a syntax, morphology and lexicon. This metalanguage is organised according to a series of meta-rules, some of which are explicitly stated while others can be deduced. Despite differences in the analysis from that of modern linguistics, Pāṇini's work has been found valuable and

23296-514: The literary works. The Indian tradition, states Winternitz , has favored the learning and the usage of multiple languages from the ancient times. Sanskrit was a spoken language in the educated and the elite classes, but it was also a language that must have been understood in a wider circle of society because the widely popular folk epics and stories such as the Ramayana , the Mahabharata ,

23478-511: The modern age include the Samaveda , Yajurveda , Atharvaveda , along with the embedded and layered Vedic texts such as the Brahmanas , Aranyakas , and the early Upanishads . These Vedic documents reflect the dialects of Sanskrit found in the various parts of the northwestern, northern, and eastern Indian subcontinent. According to Michael Witzel, Vedic Sanskrit was a spoken language of

23660-429: The more advanced Classical Sanskrit. Rituals and the rites-of-passage ceremonies have been and continue to be the other occasions where a wide spectrum of people hear Sanskrit, and occasionally join in to speak some Sanskrit words such as namah . Classical Sanskrit is the standard register as laid out in the grammar of Pāṇini , around the fourth century BCE. Its position in the cultures of Greater India

23842-401: The most advanced analysis of linguistics until the twentieth century. Pāṇini's comprehensive and scientific theory of grammar is conventionally taken to mark the start of Classical Sanskrit. His systematic treatise inspired and made Sanskrit the preeminent Indian language of learning and literature for two millennia. It is unclear whether Pāṇini himself wrote his treatise or he orally created

24024-602: The most archaic poems of the Iranian and Greek language families, the Gathas of old Avestan and Iliad of Homer . As the Rigveda was orally transmitted by methods of memorisation of exceptional complexity, rigour and fidelity, as a single text without variant readings, its preserved archaic syntax and morphology are of vital importance in the reconstruction of the common ancestor language Proto-Indo-European . Sanskrit does not have an attested native script: from around

24206-418: The naval prototype NP-2 successfully carried out its first arrested landing and ski-jump assisted take-off from the aircraft carrier INS  Vikramaditya . In July 2020, the DRDO announced that the plan to develop an LCA Mark 2 Navy had been dropped and they were working on a new carrier-borne fighter according to the Indian Navy's multi-role carrier borne fighter requirement floated in 2016 to replace

24388-408: The nuclear bomb under V. S. R. Arunachalam and the Indian missile programme was launched under A. P. J. Abdul Kalam . Ramanna pushed forward with a Uranium enrichment program and despite the sanctions, India imported heavy water required as a neutron moderator in the nuclear reactors , from countires like China, Norway and Soviet Union through a middleman. Though Rajiv Gandhi , who became

24570-425: The number of joints or rivets , increases the aircraft's structural integrity and lowers its susceptibility to fatigue cracks. The tailfin is a monolithic honeycomb structure , reducing the manufacturing cost by 80% compared to traditional methods. Initially the Tejas prototypes were equipped with a radome made out of Kevlar which was replaced with a quartz radome in the production aircraft. The naval LCA has

24752-597: The numbers are thought to signify a wish to be aligned with the prestige of the language. Sanskrit has been taught in traditional gurukulas since ancient times; it is widely taught today at the secondary school level. The oldest Sanskrit college is the Benares Sanskrit College founded in 1791 during East India Company rule . Sanskrit continues to be widely used as a ceremonial and ritual language in Hindu and Buddhist hymns and chants . In Sanskrit,

24934-403: The oral transmission of the texts is reliable: they are ceremonial literature, where the exact phonetic expression and its preservation were a part of the historic tradition. However some scholars have suggested that the original Ṛg-veda differed in some fundamental ways in phonology compared to the sole surviving version available to us. In particular that retroflex consonants did not exist as

25116-431: The other." Reinöhl further states that there is a symmetric relationship between Dravidian languages like Kannada or Tamil, with Indo-Aryan languages like Bengali or Hindi, whereas the same relationship is not found for non-Indo-Aryan languages, for example, Persian or English: A sentence in a Dravidian language like Tamil or Kannada becomes ordinarily good Bengali or Hindi by substituting Bengali or Hindi equivalents for

25298-414: The possible influence of Dravidian on Sanskrit is only one of many items of syntactic assimilation, not least among them the large repertoire of morphological modality and aspect that, once one knows to look for it, can be found everywhere in classical and postclassical Sanskrit". The main influence of Dravidian on Sanskrit is found to have been concentrated in the timespan between the late Vedic period and

25480-439: The previous 1,500 years when "great experiments in moral and aesthetic imagination" marked the Indian scholarship using Classical Sanskrit, states Pollock. Scholars maintain that the Sanskrit language did not die, but rather only declined. Jurgen Hanneder disagrees with Pollock, finding his arguments elegant but "often arbitrary". According to Hanneder, a decline or regional absence of creative and innovative literature constitutes

25662-480: The problems of interpretation and misunderstanding. The purifying structure of the Sanskrit language removes these imperfections. The early Sanskrit grammarian Daṇḍin states, for example, that much in the Prakrit languages is etymologically rooted in Sanskrit, but involves "loss of sounds" and corruptions that result from a "disregard of the grammar". Daṇḍin acknowledged that there are words and confusing structures in Prakrit that thrive independent of Sanskrit. This view

25844-500: The radar performance in air-to-air and air-to-sea modes at various altitudes were carried out in 2010. Flutter vibration tests were also carried out in different configurations at high angle of attack (AoA) to assess the structural integrity across the flight envelope . LSP-4 completed the successful trial of BDL developed Counter Measure Dispensing System (CMDS) with R-73 missile on 2 December 2010. It worked well Open Architecture Mission Computer and Digital Stores Management System. In

26026-609: The regional Prakrit languages, which makes it likely that the interaction, the sharing of words and ideas began early in the Indian history. As the Indian thought diversified and challenged earlier beliefs of Hinduism, particularly in the form of Buddhism and Jainism , the Prakrit languages such as Pali in Theravada Buddhism and Ardhamagadhi in Jainism competed with Sanskrit in the ancient times. However, states Paul Dundas , these ancient Prakrit languages had "roughly

26208-497: The relationship between various Indo-European languages, the origin of all these languages may possibly be in what is now Central or Eastern Europe, while the Indo-Iranian group possibly arose in Central Russia. The Iranian and Indo-Aryan branches separated quite early. It is the Indo-Aryan branch that moved into eastern Iran and then south into South Asia in the first half of the 2nd millennium BCE. Once in ancient India,

26390-792: The required mission map on pilot display, an upgraded IFF+ from older identification friend or foe system. To better accommodate the pilots, cockpit floor is also reshaped. The upgraded Tejas Mark 1A will have a reduced turnaround time. Tejas Mark 1A will use indigenously developed Angad electronic warfare suite and DRDO Advanced Self Protection Jammer pod. BEL will supply 20 types of locally developed critical avionics and upgrades such as Digital Flight Control Computers from ADA , Air Data Computer from DRDO , Weapon Computers from ADE , Radar Warning Receiver from Combat Aircraft Systems Development and Integration Centre (CASDIC) and Head-up display from Central Scientific Instruments Organisation (CSIO) from 2023 to 2028 for ₹2,400 crore. In order to produce

26572-562: The role of language, the ontological status of painting word-images through sound, and the need for rules so that it can serve as a means for a community of speakers, separated by geography or time, to share and understand profound ideas from each other. These speculations became particularly important to the Mīmāṃsā and the Nyaya schools of Hindu philosophy, and later to Vedanta and Mahayana Buddhism, states Frits Staal —a scholar of Linguistics with

26754-496: The same relationship to Sanskrit as medieval Italian does to Latin". The Indian tradition states that the Buddha and the Mahavira preferred the Prakrit language so that everyone could understand it. However, scholars such as Dundas have questioned this hypothesis. They state that there is no evidence for this and whatever evidence is available suggests that by the start of the common era, hardly anybody other than learned monks had

26936-446: The second half of 2012, the Tejas fleet was grounded for over three months and the ejection system had to be modified to resume flight tests by the end of 2012. In 2013, Tejas (LSP-7) conducted an inflight engine relight test at high altitude to assess the engine response on flameout, a critical parameter for operational clearance. The inflight engine relight test is crucial for single engine combat aircraft. On 15 April 2023, HAL received

27118-556: The semi-nomadic Aryans . The Vedic Sanskrit language or a closely related Indo-European variant was recognized beyond ancient India as evidenced by the " Mitanni Treaty" between the ancient Hittite and Mitanni people, carved into a rock, in a region that now includes parts of Syria and Turkey. Parts of this treaty, such as the names of the Mitanni princes and technical terms related to horse training, for reasons not understood, are in early forms of Vedic Sanskrit. The treaty also invokes

27300-459: The single-piece rudder and two airbrakes , located in the upper rear part of the fuselage , one each on either side of the fin. Since the Tejas is a relaxed static stability design, it is equipped with a NAL-developed full authority quadruplex digital fly-by-wire flight control system and an open architecture digital flight control computer developed by BEL. Its flight control surfaces are controlled by hybrid electro-hydraulic actuators through

27482-607: The single-seat NP-2 , based on the Tejas Mark 1 design, to carryout carrier suitability certification and weapons integration. Under Phase 2, two single-seat prototypes were planned to be built, based on the Tejas Mark 2 design, with further design optimisation and integration of the General Electric F414 INS6 engine. The first naval prototype NP-1 was rolled out in July 2010, and made its first flight on 27 April 2012. The naval LCA has stronger landing gear to absorb

27664-461: The sixth country to join the nuclear club . Shortly after the tests, Prime Minister Vajpayee appeared before the press corps and made the following short statement: Today, at 15:45 hours, India conducted three underground nuclear tests in the Pokhran range. The tests conducted today were with a fission device, a low yield device and a thermonuclear device. The measured yields are in line with expected values. Measurements have also confirmed that there

27846-615: The social structures such as the role of the poet and the priests, the patronage economy, the phrasal equations, and some of the poetic metres. While there are similarities, state Jamison and Brereton, there are also differences between Vedic Sanskrit, the Old Avestan, and the Mycenaean Greek literature. For example, unlike the Sanskrit similes in the Ṛg-veda, the Old Avestan Gathas lack simile entirely, and it

28028-508: The test never progressed. With Rao's term ending in 1996, the next two years saw multiple governments being formed. Atal Bihari Vajpayee , who was a strong advocate of nuclear weaponization, came to power following the 1998 general elections . Vajpayee had earlier declared that if re-voted to power, his government would induct nuclear weapons and declare India's might to gather respect. Soon after assuming power in March 1998, Vajpayee organized

28210-409: The test sites without being detected. Work was mostly done during night, and equipment was returned to the original place during the day to give the impression that it was never moved. Bomb shafts were dug under camouflage netting and the dug-out sand was shaped like natural sand dunes . Cables and sensors were either covered with sand or concealed using native vegetation. A select group was involved in

28392-632: The tests which are not favorable to the peace and stability in the region and called for the international community to pressurize India to cease the development of nuclear weapons. It further rejected claims of India's stated rationale of needing nuclear capabilities to counter a Chinese threat as unfounded. However, permanent members of the United Nations Security Council such as the United Kingdom , France , and Russia refrained from making any statements condemning

28574-544: The tests. Pakistan issued a statement blaming India for instigating a nuclear arms race in the region with Prime Minister Nawaz Sharif stating that his country will take appropriate action. Pakistan carried out six nuclear tests under the codename Chagai-I on 28 May 1998 and Chagai-II on 30 May 1998. Pakistan's leading nuclear physicist , Pervez Hoodbhoy , held India responsible for Pakistan's nuclear test experiments. Pakistan's subsequent tests invited similar condemnation and economic sanctions. On June 6,

28756-491: The time with capabilities to air drop nuclear weapons. In late 1985, a study group commissioned by the Prime Minister outlined a plan for the production of 70 to 100 nuclear warheads and a strict no first use policy. In 1989 , V.P. Singh formed the government , which collapsed within two years and this period of instability caused a snag in the nuclear weapons programme. Foreign relations between India and Pakistan severely worsened when India accused Pakistan of supporting

28938-653: The turn of the 1st-millennium CE, it has been written in various Brahmic scripts , and in the modern era most commonly in Devanagari . Sanskrit's status, function, and place in India's cultural heritage are recognized by its inclusion in the Constitution of India 's Eighth Schedule languages . However, despite attempts at revival, there are no first-language speakers of Sanskrit in India. In each of India's recent decennial censuses, several thousand citizens have reported Sanskrit to be their mother tongue, but

29120-459: The turnaround time by 30% and doubles the sortie rate. In September 2018, the Tejas successfully completed its mid-air refuelling trials required for the aircraft to obtain its FOC. In January 2019, HAL received permission from CEMILAC to start production of the FOC standard Tejas. On 20 February 2019, during the Aero India 2019 show, FOC was formally awarded to the Tejas. The HAL handed over

29302-408: The variants in the usage of Sanskrit in different regions of India. The ten Vedic scholars he quotes are Āpiśali, Kaśyapa , Gārgya, Gālava, Cakravarmaṇa, Bhāradvāja , Śākaṭāyana, Śākalya, Senaka and Sphoṭāyana. In the Aṣṭādhyāyī , language is observed in a manner that has no parallel among Greek or Latin grammarians. Pāṇini's grammar, according to Renou and Filliozat, is a classic that defines

29484-564: The vernacular Prakrits. Many Sanskrit dramas indicate that the language coexisted with the vernacular Prakrits. The cities of Varanasi , Paithan , Pune and Kanchipuram were centers of classical Sanskrit learning and public debates until the arrival of the colonial era. According to Lamotte , Sanskrit became the dominant literary and inscriptional language because of its precision in communication. It was, states Lamotte, an ideal instrument for presenting ideas, and as knowledge in Sanskrit multiplied, so did its spread and influence. Sanskrit

29666-470: The war, the work on building a nuclear device continued. The hardware began to be built in early 1972 and the Prime Minister authorized the development of a nuclear test device in September 1972. On 18 May 1974, India tested a implosion-type fission device at the Indian Army 's Pokhran Test Range under the code name Smiling Buddha . The test was called as a Peaceful Nuclear Explosive (PNE) and

29848-502: The Ṛg-veda is distinctly more archaic than other Vedic texts, and in many respects, the Rigvedic language is notably more similar to those found in the archaic texts of Old Avestan Zoroastrian Gathas and Homer's Iliad and Odyssey . According to Stephanie W. Jamison and Joel P. Brereton – Indologists known for their translation of the Ṛg-veda – the Vedic Sanskrit literature "clearly inherited" from Indo-Iranian and Indo-European times

30030-408: Was a spoken language ( bhasha ) used by the cultured and educated. Some sutras expound upon the variant forms of spoken Sanskrit versus written Sanskrit. Chinese Buddhist pilgrim Xuanzang mentioned in his memoir that official philosophical debates in India were held in Sanskrit, not in the vernacular language of that region. According to Sanskrit linguist professor Madhav Deshpande, Sanskrit

30212-427: Was a spoken language in a colloquial form by the mid-1st millennium BCE which coexisted with a more formal, grammatically correct form of literary Sanskrit. This, states Deshpande, is true for modern languages where colloquial incorrect approximations and dialects of a language are spoken and understood, along with more "refined, sophisticated and grammatically accurate" forms of the same language being found in

30394-769: Was a twin-seater aircraft, while the second naval prototype, designated as NP-2, was a single seater. Both naval prototypes were used extensively for various aircraft carrier -related trials at the Shore Based Test Facility in Goa. NP-2 was used in the actual carrier trials, where it made an arrested recovery and ski-jump assisted take-off from the aircraft carrier INS  Vikramaditya in January 2020. The first Limited Series Production aircraft (LSP-1) performed its maiden flight on 25 April 2007. A total of seven limited series production (LSP) aircraft were built. The LSPs were extensively used for developmental trials such as weapon testing – involving test firing of

30576-472: Was adopted voluntarily as a vehicle of high culture, arts, and profound ideas. Pollock disagrees with Lamotte, but concurs that Sanskrit's influence grew into what he terms a "Sanskrit Cosmopolis" over a region that included all of South Asia and much of southeast Asia. The Sanskrit language cosmopolis thrived beyond India between 300 and 1300 CE. Today, it is believed that Kashmiri is the closest language to Sanskrit. Reinöhl mentions that not only have

30758-738: Was also the language of some of the oldest surviving, authoritative and much followed philosophical works of Jainism such as the Tattvartha Sutra by Umaswati . The Sanskrit language has been one of the major means for the transmission of knowledge and ideas in Asian history. Indian texts in Sanskrit were already in China by 402 CE, carried by the influential Buddhist pilgrim Faxian who translated them into Chinese by 418 CE. Xuanzang , another Chinese Buddhist pilgrim, learnt Sanskrit in India and carried 657 Sanskrit texts to China in

30940-480: Was converted for this purpose. The development of multi-mode was not smooth, as it suffered some setbacks. By 2005, only two radar modes – the air-to-air look-up and look-down - were confirmed to have been successfully tested. The performance of several other modes that had been tested were suboptimal. The problem with the radar was mainly attributed to the lack of compatibility between the LRDE/HAL multi mode radar and

31122-500: Was engaged in a war with China and with China conducting its own nuclear test in 1964, it accelerated India's need to develop nuclear weapons. With two reactors operational in early 1960s, research progressed in learning and development of know-how to manufacture nuclear weapons. With the unexpected deaths of then Prime Minister Nehru in 1964 and Bhabha in 1966, the programme slowed down. The incoming prime minister Lal Bahadur Shastri appointed physicist Vikram Sarabhai as

31304-458: Was established which was responsible for the atomic development programme and was allocated a significant amount of the defence budget in the subsequent years. In 1956, the first nuclear reactor became operational at Bhabha Atomic Research Centre (BARC), becoming the first operating reactor in Asia. In 1961, India commissioned a reprocessing plant to produce weapon grade Plutonium . In 1962, India

31486-468: Was intended to be used. However, DRDO decided to develop an indigenous multi-mode radar for the Tejas. HAL's Hyderabad division and the DRDO's Electronics and Radar Development Establishment (LRDE) laboratory were selected to jointly lead the MMR programme, and work commenced in 1997. The Centre for Airborne Systems (CABS) was responsible for the MMR's test programme. An HAL-748 airborne surveillance aircraft

31668-480: Was no release of radioactivity into the atmosphere. These were contained explosions like the experiment conducted in May 1974. I warmly congratulate the scientists and engineers who have carried out these successful tests. On 13 May 1998, India declared the series of tests to be over after this. News of the tests were greeted with jubilation and large-scale approval by general public in India. The Bombay Stock Exchange registered significant gains. The media praised

31850-410: Was not consistent with her national security interest. Canada criticized India's actions. Japan imposed economic sanctions which included freezing all new loans and grants except for humanitarian aid. Few other nations also imposed sanctions on India, primarily in the form of suspension of foreign aid and government-to-government credit lines. China stated that it was seriously concerned about

32032-419: Was planned on 11 May. The high yield thermonuclear device was placed in a shaft code named White House , which was approximately 230 metres [m] (750 ft) deep, the fission bomb was placed in a 150 metres (490 ft) deep shaft code named Taj Mahal , and the first sub-kiloton device in shaft Kumbhkaran . The first three devices were placed in their respective shafts on 10 May. The first device to be placed

32214-571: Was terminated following a US embargo in response to India's second nuclear tests in 1998. This delayed the programme partly by about 18 months. Later India indigenously developed a quadruplex digital fly-by-wire flight control system for Tejas. The CLAW team completed the design and integration of the flight control laws with the flight control system software, with the aid of an Iron Bird test rig. The quadruplex digital fly-by-wire flight control system conducted over 50 hours of pilot testing on Iron Bird Test Rig. On 4 January 2001, on its maiden flight,

32396-435: Was the first to have their MiG-21 Bisons replaced with the Tejas. Tejas has three production variants - Tejas Mark 1, Mark 1A and Tejas trainer/light attack aircraft. The IAF currently has placed an order for 123 Tejas and is planning to procure 97 more. The IAF plans to procure at least 324 aircraft or 18 squadrons of Tejas in all variants, including the heavier Tejas Mark 2 which is currently being developed. As of 2022,

32578-423: Was the first to have their MiG-21s replaced by Tejas aircraft at the base. The FOC campaign began in December 2014. Two critical parameters set by IAF for FOC clearance was expansion of angle of attack from 24 degree in IOC-II to 28 degree in FOC and inflight refueling capability. In February 2018, as part of the FOC campaign, the Tejas carried out a "hot refuelling" - refuelling with engine running, which shortens

32760-409: Was the result of the collaboration of ADA, Research Centre Imarat (RCI) and Central Manufacturing Technology Institute (CMTI). The technology is ready to be integrated with production variants of Tejas Mk 1A as it successfully completed flight trials. These are being produced at Accessories Division, HAL, Lucknow . The HAL Tejas design has been further developed into the Tejas Mark 2, incorporating

32942-403: Was the sub-kiloton device, which was sealed by the army engineers by 8:30 PM. The thermonuclear device was lowered and sealed by 4 AM on the next day with the fission device being placed by 7:30 AM. The shafts were L-shaped, with a horizontal chamber used for the test devices. The timing of the tests was pursuant to the local weather conditions, and the test sequence was initiated in

33124-442: Was visualized as "pervading all creation", another representation of the world itself; the "mysterious magnum" of Hindu thought. The search for perfection in thought and the goal of liberation were among the dimensions of sacred sound, and the common thread that wove all ideas and inspirations together became the quest for what the ancient Indians believed to be a perfect language, the "phonocentric episteme" of Sanskrit. Sanskrit as
