There are also forming capabilities including CNC filament winding, vacuum infusion, wet lay-up, compression moulding , and thermoplastic moulding, to name a few. The practice of curing ovens and paint booths is also required for some projects. The composite parts finishing
294-419: A brand new phased array radar that supposedly performed better, rumored to be Zhuk-MSF. In addition to the easy of integration, the advantage of Pero passive electronically scanned array equipped Panda radar was its weight. All other radars offered for Su-30MK2 upgrade increase weight significantly that the center of the gravity of the aircraft is altered, resulting in the need to modify the airframe and redesign
392-413: A central core of end grain balsa wood , bonded to surface skins of light alloy or GRP. These generate low-weight, high rigidity materials. Particulate composites have particle as filler material dispersed in matrix, which may be nonmetal, such as glass, epoxy. Automobile tire is an example of particulate composite. Advanced diamond-like carbon (DLC) coated polymer composites have been reported where

There is not any confirmation for any follow-on orders of Sokol radar and unlike the capability optronic pod, this radar capability is not known to be added to the earlier Su-30MKKs during the incremental upgrades. In the early 2000s, Russia had authorized the export of Pero passive electronically scanned array radar designed by Tikhomirov, to China. The Pero antenna can be easily integrated into
784-466: A different series of numbers with a different suffix (i.e., SA-N- versus SA-) for these systems. The names are kept the same as a convenience. Where there is no corresponding system, a new name is devised. The Soviet Union did not always assign official "popular names" to its aircraft, but unofficial nicknames were common as in any air force . Generally, Soviet pilots did not use the NATO names, preferring
882-483: A final decision by the end of 2007, and many Russian and Chinese sources have claimed that domestic Chinese HUDs of Western origin perform better and weigh much less, and China thus planned to adopt their own avionics in the next incremental upgrade, but such claims have yet to be confirmed by western sources and official sources of Chinese and Russian governments. In response, Tikhomirov subsequently offered China its N-011M Bars passive electronically scanned array radar,
980-1061: A high deformation setting and are often used in deployable systems where structural flexing is advantageous. Although high strain composites exhibit many similarities to shape-memory polymers, their performance is generally dependent on the fibre layout as opposed to the resin content of the matrix. Composites can also use metal fibres reinforcing other metals, as in metal matrix composites (MMC) or ceramic matrix composites (CMC), which includes bone ( hydroxyapatite reinforced with collagen fibres), cermet (ceramic and metal), and concrete . Ceramic matrix composites are built primarily for fracture toughness , not for strength. Another class of composite materials involve woven fabric composite consisting of longitudinal and transverse laced yarns. Woven fabric composites are flexible as they are in form of fabric. Organic matrix/ceramic aggregate composites include asphalt concrete , polymer concrete , mastic asphalt , mastic roller hybrid, dental composite , syntactic foam , and mother of pearl .

#17327840365551176-1064: A matrix of cement . Concrete is an inexpensive material, and will not compress or shatter even under quite a large compressive force. However, concrete cannot survive tensile loading (i.e., if stretched it will quickly break apart). Therefore, to give concrete the ability to resist being stretched, steel bars, which can resist high stretching (tensile) forces, are often added to concrete to form reinforced concrete . Fibre-reinforced polymers include carbon-fiber-reinforced polymers and glass-reinforced plastic . If classified by matrix then there are thermoplastic composites , short fibre thermoplastics , long fibre thermoplastics or long-fiber-reinforced thermoplastics . There are numerous thermoset composites, including paper composite panels . Many advanced thermoset polymer matrix systems usually incorporate aramid fibre and carbon fibre in an epoxy resin matrix.

The Flanker family aircraft has the problem of the reduction of maximum g-force level being decreased to 7g from the 9g at speed between Mach 0.7 to Mach 0.9, and this problem was completely solved on Su-30MKK by adopting new measures. According to the Sukhoi Design Bureau, Su-30MKK is the first of
1568-522: A native Russian nickname. An exception was that Soviet airmen appreciated the MiG-29 's codename "Fulcrum", as an indication of its pivotal role in Soviet air defence. To reduce the risk of confusion, unusual or made-up names are allocated, the idea being that the names chosen are unlikely to occur in normal conversation and are easier to memorise. For fixed-wing aircraft, the number of syllables indicates
1666-802: A non-corrosive alternative to galvanized steel. In 2007, an all-composite military Humvee was introduced by TPI Composites Inc and Armor Holdings Inc, the first all-composite military vehicle . By using composites the vehicle is lighter, allowing higher payloads. In 2008, carbon fibre and DuPont Kevlar (five times stronger than steel) were combined with enhanced thermoset resins to make military transit cases by ECS Composites creating 30-percent lighter cases with high strength. Pipes and fittings for various purpose like transportation of potable water, fire-fighting, irrigation, seawater, desalinated water, chemical and industrial waste, and sewage are now manufactured in glass reinforced plastics.

Modifications of existing designs were given descriptive terms, such as " Whiskey Long Bin ". From the 1980s, new designs were given names derived from Russian words, such as " Akula ", or "shark". These names did not correspond to the Soviet names. Coincidentally, "Akula", which
2842-1579: Is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions . Composite materials with more than one distinct layer are called composite laminates . Typical engineered composite materials include: There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with common materials, as well as composite materials inspired from animals and natural sources with low carbon footprint. More recently researchers have also begun to actively include sensing, actuation, computation, and communication into composites, which are known as robotic materials . Composite materials are generally used for buildings , bridges , and structures such as boat hulls , swimming pool panels, racing car bodies, shower stalls, bathtubs , storage tanks , imitation granite , and cultured marble sinks and countertops. They are also being increasingly used in general automotive applications. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments. The earliest composite materials were made from straw and mud combined to form bricks for building construction . Ancient brick-making

High density composites are an economically viable option when certain materials are deemed hazardous and are banned (such as lead) or when secondary operations costs (such as machining, finishing, or coating) are a factor. There have been several studies indicating that interleaving stiff and brittle epoxy-based carbon-fiber-reinforced polymer laminates with flexible thermoplastic laminates can help to make highly toughened composites that show improved impact resistance. Another interesting aspect of such interleaved composites

Ferromagnetic composites, including those with a polymer matrix consisting, for example, of nanocrystalline filler of Fe-based powders and polymers matrix. Amorphous and nanocrystalline powders obtained, for example, from metallic glasses can be used. Their use makes it possible to obtain ferromagnetic nanocomposites with controlled magnetic properties. Fibre-reinforced composite materials have gained popularity (despite their generally high cost) in high-performance products that need to be lightweight, yet strong enough to take harsh loading conditions such as aerospace components ( tails , wings , fuselages , propellers ), boat and scull hulls, bicycle frames, and racing car bodies. Other uses include fishing rods , storage tanks , swimming pool panels, and baseball bats . The Boeing 787 and Airbus A350 structures including

Such problems does not exist if Panda radar is adopted because it only increases the weight by a mere 20 kg, which will be compensated by the redesign of SILS-30 HUD to reduce its weight by 20 kg, thus balancing out the weight increase of the radar. This claim of Timkhomirov design bureau is confirmed by both the Sukhoi design bureau and Russkaya Avionika bureau, which claimed to media reporters at 2006 Zhuhai Airshow in China that such modification had already been successfully completed. China, however, had not made

Russian sources have confirmed the claims of domestic Chinese sources that an indigenous Chinese system developed is near its completion and it will be used to replace the original Russian system. However, this has yet to be confirmed by western sources and official Chinese governmental sources, which only acknowledged in
6566-414: The individual phases are given by Hooke's Law, σ β = E β ϵ {\displaystyle \sigma _{\beta }=E_{\beta }\epsilon } σ α = E α ϵ {\displaystyle \sigma _{\alpha }=E_{\alpha }\epsilon } Combining these equations gives that the overall stress in
6664-651: The isostrain case, ϵ C = ϵ α = ϵ β = ϵ {\displaystyle \epsilon _{C}=\epsilon _{\alpha }=\epsilon _{\beta }=\epsilon } Assuming that the composite has a uniform cross section, the stress on the composite is a weighted average between the two phases, σ C = σ α V α + σ β V β {\displaystyle \sigma _{C}=\sigma _{\alpha }V_{\alpha }+\sigma _{\beta }V_{\beta }} The stresses in
6762-764: The less stiff, amorphous phase. Polymeric materials can range from 0% to 100% crystallinity aka volume fraction depending on molecular structure and thermal history. Different processing techniques can be employed to vary the percent crystallinity in these materials and thus the mechanical properties of these materials as described in the physical properties section. This effect is seen in a variety of places from industrial plastics like polyethylene shopping bags to spiders which can produce silks with different mechanical properties. In many cases these materials act like particle composites with randomly dispersed crystals known as spherulites. However they can also be engineered to be anisotropic and act more like fiber reinforced composites. In
6860-406: The matrix nature, such as solidification from the melted state for a thermoplastic polymer matrix composite or chemical polymerization for a thermoset polymer matrix . According to the requirements of end-item design, various methods of moulding can be used. The natures of the chosen matrix and reinforcement are the key factors influencing the methodology. The gross quantity of material to be made
6958-625: The matrix. Since a shape-memory polymer resin is used as the matrix, these composites have the ability to be easily manipulated into various configurations when they are heated above their activation temperatures and will exhibit high strength and stiffness at lower temperatures. They can also be reheated and reshaped repeatedly without losing their material properties. These composites are ideal for applications such as lightweight, rigid, deployable structures; rapid manufacturing; and dynamic reinforcement. High strain composites are another type of high-performance composites that are designed to perform in
7056-563: The most powerful Russian airborne radar on any of its exported aircraft, but China once again rejected the offer. Many claimed that the reason for the rejection was that Chinese discovered the same problem India had during the evaluation of the radar: although the N-011M Bars passive electronically scanned array radar offered longer range and better resistance to jamming, it had the problem of accurately and correct identifying targets at long range, while others claims China simply did not want
7154-420: The moulded panel. There is always a lower mould, and sometimes an upper mould in this convention. Part construction commences by applying materials to the lower mould. Lower mould and upper mould are more generalized descriptors than more common and specific terms such as male side, female side, a-side, b-side, tool side, bowl, hat, mandrel, etc. Continuous manufacturing utilizes a different nomenclature. Usually,
7252-451: The moulded product is referred to as a panel. It can be referred to as casting for certain geometries and material combinations. It can be referred to as a profile for certain continuous processes. Some of the processes are autoclave moulding , vacuum bag moulding , pressure bag moulding , resin transfer moulding , and light resin transfer moulding . Other types of fabrication include casting , centrifugal casting, braiding (onto
7350-406: The new avionics and upgrades of current avionics were specially developed to meet the Chinese requirement, and subsequently used on other members of the Flanker family, including the more advanced versions that appeared later, and this was mainly due to the fact that the funding for Su-30MKK was readily available in comparison to others. The primary contractors / system integrator for Su-30MKK avionics
7448-466: The new displays remains the same as that of Su-30MKK. One of the important avionic upgrades of Su-30MK2 is the incorporation of several electro-optical ( optronics ) pods, a capability that is added to earlier Su-30MKK during upgrades. Two types of Russian optronic pods are sold to China for Su-30MK2, but the open architecture and other advanced designs enabled the aircraft to carry domestic optronic pods as well. This capability of Su-30MK2 has been added to
7546-485: The original Su-30MK, but contrary to what was once erroneously claimed by some western sources, Sukhoi Design Bureau revealed later that the increased space in the rudders were used for additional fuel tanks, instead of larger communication UHF antenna. The capacity of the fuel tanks in the wings is also increased. A twin nose landing gear of size 620 mm x 180 mm has replaced the single nose landing gear of size 680 mm x 260 mm used on Su-30MK to accommodate
7644-422: The original Su-30MKKs during the incremental upgrades. The Russian optronic pods included: In 2000, China placed an order of passive electronically scanned array radar named Sokol (Falcon), designed by Phazotron , while the radar was still under development, it is reported that China had either partially funded or joined the development, but this can not be confirmed. All twenty units were delivered in 2004 after
7742-419: The original four, thus fully utilizing the capability of the SUV-VEP subsystem of the onboard fire control system. The diameter of the antenna array is increased to 980 mm from the 960 mm of Zhuk-MS/MSE. The scan sector of the radar is 170 degrees and the elevation of the scan is from −40 degrees to +56 degrees. The radar has three receivers and a gain of 37 dB. When used against surface targets like
7840-477: The product or structure receives options to choose an optimum combination from the variety of matrix and strengthening materials. To shape the engineered composites, it must be formed. The reinforcement is placed onto the mould surface or into the mould cavity. Before or after this, the matrix can be introduced to the reinforcement. The matrix undergoes a melding event which sets the part shape necessarily. This melding event can happen in several ways, depending upon
7938-465: The same system used by India. However, both claims contradict with the official explanation of the Chinese government: the new radar weighs more than 650 kg and caused the center of gravity of the aircraft to alter significantly, thus greatly degraded the aerodynamic performance and weapon payload arrangement of the Su-30MKK, which is far less adaptable to the new heavy radar than Su-30MKI , because
8036-404: The starting raw ingredients. There are several broad categories, each with numerous variations. The most common are known as polyester , vinyl ester , epoxy , phenolic , polyimide , polyamide , polypropylene , PEEK , and others. The reinforcement materials are often fibres but also commonly ground minerals. The various methods described below have been developed to reduce the resin content of
8134-447: The summary of the state-of-the-art techniques for fabrication of the 3D structure of graphene, and the examples of the use of these foam like structures as a core for their respective polymer composites. Although the two phases are chemically equivalent, semi-crystalline polymers can be described both quantitatively and qualitatively as composite materials. The crystalline portion has a higher elastic modulus and provides reinforcement for
8232-477: The thread to screw in the valve. On 5 September 2019, HMD Global unveiled the Nokia 6.2 and Nokia 7.2 which are claimed to be using polymer composite for the frames. Composite materials are created from individual materials. These individual materials are known as constituent materials, and there are two main categories of it. One is the matrix ( binder ) and the other reinforcement . A portion of each kind
8330-463: The two were based on two totally different airframes, a fact that is confirmed by Jane's all the World's Aircraft . If the new radar was to be adopted, canards must be added and flight control software must be also modified for Su-30MKK just to remain the same level of performance as before, and thus, in addition to paying for the more expensive new radars, a huge amount of money must be spent in upgrading
8428-588: The type of the aircraft's engine. Single-syllable code names denote reciprocating engine or turboprop , while two-syllable code names denote jet engine . Bombers have names starting with the letter "B", and names like "Badger" ( Tupolev Tu-16 ), "Blackjack" ( Tupolev Tu-160 ) and "Bear" ( Tupolev Tu-95 ) have been used. "Frogfoot", the reporting name for the Sukhoi Su-25 , references the aircraft's close air support role. Transports have names starting with "C" (for "cargo"), resulting in names like "Condor" for
8526-571: The usual radar supplier for the Flanker family. Some domestic Chinese media have claimed the phased array radar is the Zhuk-MSF, but this has yet to be confirmed. It is also possible that the Chinese may use the same radar used on its newest J-11b's radar which will significantly increase Su-30MKK's performance, because J-11B's radar will increase the Su-30MKK's radar range up to 350 km, and allow it to engage up to four air-to-air and four ground targets. The fire control system on board integrates
8624-464: The wing tips, and the APP-50 decoy launcher is mounted near the tail cone with 96 decoys of different kinds. Domestic Chinese electronic warfare systems including BM/KG300G and KZ900 can also be carried after modification of onboard system, but such modification was neither part of the original deal nor the upgrade deal with Russians, instead, this was implemented indigenously by Chinese themselves during
8722-414: The wings and fuselage are composed largely of composites. Composite materials are also becoming more common in the realm of orthopedic surgery , and it is the most common hockey stick material. Carbon composite is a key material in today's launch vehicles and heat shields for the re-entry phase of spacecraft . It is widely used in solar panel substrates, antenna reflectors and yokes of spacecraft. It
8820-443: Was RPKB Instrumentation Design Bureau headquartered at Ramenskoye , and many new measures were adopted to meet the Chinese requirement, such as the open architecture software design. The development of avionics for the Su-30MKK was also assisted by 12 Ukrainian factories. The encrypted VHF / UHF communication radio of Su-30MKK has a maximum range in excess of 400 km, while the encrypted HF communication radio of Su-30MKK has
8918-407: Was assigned to an attack submarine by NATO, was the actual Soviet name for the ballistic missile submarine NATO named " Typhoon-class ". The NATO names for submarines of the People's Republic of China are taken from Chinese dynasties . Composite material A composite material (also called a composition material or shortened to composite , which is the common name) is a material which
9016-442: Was documented by Egyptian tomb paintings . Wattle and daub is one of the oldest composite materials, at over 6000 years old. Concrete is also a composite material, and is used more than any other synthetic material in the world. As of 2009 , about 7.5 billion cubic metres of concrete are made each year Concrete is the most common artificial composite material of all and typically consists of loose stones (aggregate) held with
9114-590: Was jointly developed by the Russian National Aeronautical System Science Research Academy and Russkaya Avionika JSC, designated as MVK, capable of performing ten billion FLOPS . All avionics on board is built to MIL-STD-1553 standard. There are four computers based on Baguet-55 series processor, one for central avionics control, two for information display, and one for fire control. The integrated navigational systems designated as PNS-10, incorporating
9212-485: Was named as the primary contractor. The modified SUV-VEP system adopted to upgrade Chinese Su-27SK was designated as SUV-VE, while the modified SUV-P system adopted to upgrade Chinese Su-27SK was designated as SUV-PE. The original analog dial indicator on flight dashboard of Su-27SK were replaced by two 6 in x 6 in MFI-10-6M and a MFIP-6 LCD MFDs . According to Russian claim, over 60 Chinese Su-27SK have been upgraded by
9310-508: Was no actual updates or development reported from the project of Su-30MK3. In fact, the production line of the Su-30MK2 at the Komsomolsk-on-Amur Aircraft Plant (KnAAZ) has been shut down in late 2016 after completing the very last two Su-30MK2 airframes for Vietnam , leaving space for the production of the newer Su-35S and Su-57 at the same facilities. Eventually, there was no more order or formal offering for
9408-541: Was offered to China. However, it is highly unlikely that China will adopt this newest Russian airborne radar because all models of the Su-30 series can only provide half of the power required for the 5 kW rated radar, and currently, only Sukhoi Su-35 and Sukhoi Su-37 have enough power to support this newest Russian airborne radar. Purchasing Irbis-E phased array radar would lock China into yet another deal with Russia to upgrade its Su-30MKK fleet that would greatly increase
9506-492: Was replaced by more advanced Sura-K HMS system, but Chinese have been replacing the Russian HMS with more advanced domestic system. Publicized photos and video clips from the official Chinese governmental sources such as CCTV-7 in 2007 and PLA pictorial magazine have confirmed the western claims of Chinese is replacing the original Russian helmet mounted sights (HMS) with more capable domestic ones. The new mission computer
9604-696: Was to be designated as Su-30MKK ("Modernizirovannyi Kommercheskiy Kitayski" – Modernised Commercial for China). Final details of the agreement were settled during the Zhuhai Air Show in 1998. The official agreement was signed in Russia by the Chinese Premier Zhu Rongji in March 1999. That same month, a "Bort 501 Blue" prototype made its first flight at the Zhukovsky Air Base . In November 2000, "Bort 502 Blue" attended
