126-809: The Sikorsky CH-148 Cyclone is a twin-engine, multi-role shipborne helicopter developed by the Sikorsky Aircraft Corporation for the Canadian Armed Forces . A military variant of the Sikorsky S-92 , the CH-148 is designed for shipboard operations and replaced the CH-124 Sea King , which was in Canadian Armed Forces operation from 1963 to 2018. The Cyclone entered operational service with
252-619: A World Heritage Site by UNESCO, it is believed to be the Vinland settlement of explorer Leif Erikson . (The Icelandic Skálholt map of 1570 refers to the area as "Promontorium Winlandiæ" and correctly shows it on a 51°N parallel with Bristol , England). Before and after the departure of the Norse, the island was inhabited by indigenous populations. About 500 years later, in 1497, the Italian navigator John Cabot (Zuan/Giovanni Caboto) became
378-616: A runway . In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production . Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter , not to be confused with the single-blade monocopter ) has become the most common helicopter configuration. However, twin-rotor helicopters (bicopters), in either tandem or transverse rotors configurations, are sometimes in use due to their greater payload capacity than
504-526: A "baby bonus" for each child in a family. The Confederates were led by the charismatic Joseph Smallwood , a former radio broadcaster, who had developed socialist political inclinations while working for a socialist newspaper in New York City. Following confederation, Smallwood led Newfoundland for decades as the elected premier . His policies as premier were closer to liberalism than socialism. The first flag to specifically represent Newfoundland
630-444: A collective input is made, all the blades change equally, and the result is the helicopter increasing or decreasing in altitude. A swashplate controls the collective and cyclic pitch of the main blades. The swashplate moves up and down, along the main shaft, to change the pitch of both blades. This causes the helicopter to push air downward or upward, depending on the angle of attack . The swashplate can also change its angle to move
756-712: A colonial governor on the island. After 1713, with the Treaty of Utrecht , the French ceded control of south and north shores of the island to the British. They kept only the nearby islands of St. Pierre and Miquelon , located in the fish-rich Grand Banks off the south coast. Despite some early settlements by the English, the Crown discouraged permanent, year-round settlement of Newfoundland by migratory fishery workers. Thomas Nash
882-417: A constant altitude. The pedals serve the same function in both a helicopter and a fixed-wing aircraft, to maintain balanced flight. This is done by applying a pedal input in whichever direction is necessary to center the ball in the turn and bank indicator . Due to the operating characteristics of the helicopter—its ability to take off and land vertically, and to hover for extended periods of time, as well as
1008-439: A few more flights and achieved a height of nearly 2.0 metres (6.5 ft), but it proved to be unstable and was abandoned. Newfoundland (island) Newfoundland ( / ˈ nj uː f ən ( d ) l ə n d , - l æ n d / NEW -fən(d)-lənd, -land , locally / ˌ n uː f ən ˈ l æ n d / NEW -fən- LAND ; French: Terre-Neuve , locally [taɛ̯ʁˈnœːv] ; Mi'kmaq : Ktaqmkuk )
1134-409: A fine of up to CA$ 8 million on Sikorsky for failure to meet contractual obligations. In January 2012 it was reported Sikorsky would deliver five training CH-148s in 2012, including one "fully mission capable" CH-148 by June 2012, or face a further possible $ 80 million in contract penalties. On 10 July 2012 in reference to Sikorsky missing another delivery deadline, Defence Minister Peter MacKay called
1260-445: A forerunner to the much later British Empire. Newfoundland is considered Britain's oldest colony. Settlers developed a variety of dialects associated with settlement on the island: Newfoundland English , Newfoundland French . In the 19th century, it also had a dialect of Irish known as Newfoundland Irish . The closely related Scottish Gaelic was also spoken on the island during the 19th and early 20th centuries, particularly in
1386-463: A gift by their father, would inspire the Wright brothers to pursue the dream of flight. In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt , a French inventor who demonstrated a small steam-powered model. While celebrated as an innovative use of a new metal, aluminum, the model never lifted off the ground. D'Amecourt's linguistic contribution would survive to eventually describe
SECTION 10
#17327724542281512-405: A helicopter determines the size, function and capability of that helicopter design. The earliest helicopter engines were simple mechanical devices, such as rubber bands or spindles, which relegated the size of helicopters to toys and small models. For a half century before the first airplane flight, steam engines were used to forward the development of the understanding of helicopter aerodynamics, but
1638-510: A helicopter powered by a gasoline engine with box kites attached to a mast by cables for a rotor, but it never flew. In 1906, two French brothers, Jacques and Louis Breguet , began experimenting with airfoils for helicopters. In 1907, those experiments resulted in the Gyroplane No.1 , possibly as the earliest known example of a quadcopter. Although there is some uncertainty about the date, sometime between 14 August and 29 September 1907,
1764-416: A helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The result is constant control inputs and corrections by the pilot to keep the helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift in the horizontal plane, that
1890-477: A process of rebracketing , the word is often (erroneously, from an etymological point of view) perceived by English speakers as consisting of heli- and -copter , leading to words like helipad and quadcopter . English language nicknames for "helicopter" include "chopper", "copter", "heli", and "whirlybird". In the United States military, the common slang is "helo" pronounced /ˈhiː.loʊ/. A helicopter
2016-494: A rotor. The spinning creates lift, and the toy flies when released. The 4th-century AD Daoist book Baopuzi by Ge Hong ( 抱朴子 "Master who Embraces Simplicity") reportedly describes some of the ideas inherent to rotary wing aircraft. Designs similar to the Chinese helicopter toy appeared in some Renaissance paintings and other works. In the 18th and early 19th centuries Western scientists developed flying machines based on
2142-516: A similar accident is extremely unlikely. The effectiveness of the bypass switch has been questioned as it assumes that the leak will happen within the oil cooler assembly, and that the bypass can be activated in time to maintain enough oil. In the case of the S-92 crash, a titanium stud sheared causing catastrophic oil loss through the oil filter assembly. The CH-148 has a metal and composite airframe. The four-bladed articulated composite main rotor blade
2268-441: A single main rotor, but torque created by its aerodynamic drag must be countered by an opposed torque. The design that Igor Sikorsky settled on for his VS-300 was a smaller tail rotor. The tail rotor pushes or pulls against the tail to counter the torque effect, and this has become the most common configuration for helicopter design, usually at the end of a tail boom . Some helicopters use other anti-torque controls instead of
2394-760: A solicitation for the New Shipborne Aircraft (NSA) Project. A variant of the AgustaWestland EH101 was selected and a contract was signed by the nation's governing party at the time, the Progressive Conservatives. After a change of government to the Liberal party, the EH-101 contract was cancelled. The cancellation resulted in a lengthy delay to procure a replacement aircraft. The project took on increased importance in
2520-417: A state called translational lift which provides extra lift without increasing power. This state, most typically, occurs when the airspeed reaches approximately 16–24 knots (30–44 km/h; 18–28 mph), and may be necessary for a helicopter to obtain flight. In forward flight a helicopter's flight controls behave more like those of a fixed-wing aircraft. Applying forward pressure on the cyclic will cause
2646-437: A total area of 111,390 square kilometres (43,008 sq mi). According to 2006 official Census Canada statistics, 57% of responding Newfoundland and Labradorians claim British or Irish ancestry, with 43.2% claiming at least one English parent, 21.5% at least one Irish parent, and 7% at least one parent of Scottish origin. Additionally, 6.1% claimed at least one parent of French ancestry. The island's total population as of

#17327724542282772-597: Is Corner Brook , which is situated on the Bay of Islands on the west coast of the island. The bay was named by Captain James Cook who surveyed the coast in 1767. The island of Newfoundland has numerous provincial parks such as Barachois Pond Provincial Park , considered to be a model forest, as well as two national parks. The island has many tourism opportunities, ranging from sea kayaking, camping, fishing and hunting, to hiking. The International Appalachian Trail (IAT)
2898-429: Is a cylindrical metal shaft that extends upwards from the transmission. At the top of the mast is the attachment point for the rotor blades called the hub. Main rotor systems are classified according to how the rotor blades are attached and move relative to the hub. There are three basic types: hingeless, fully articulated, and teetering; although some modern rotor systems use a combination of these. Most helicopters have
3024-535: Is a large island within the Canadian province of Newfoundland and Labrador . It is situated off the eastern coast of the North American mainland and the geographical region of Labrador . The island contains 29 percent of the province's land area, but is home to over 90% of the province's population, with about 60% of the province's population located on the small southeastern Avalon peninsula . The island
3150-569: Is a provincial Registered Heritage District, as well as a National Cultural Landscape District of Canada. This is one of only two national historic sites in Canada so recognized for their Irish heritage. Entertainment opportunities abound in the island's three cities and numerous towns, particularly during summer festivals. For nightlife, George Street , located in downtown St. John's, is closed to traffic 20 hours per day. The Mile One Stadium in St. John's
3276-460: Is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors . This allows the helicopter to take off and land vertically , to hover , and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing ( STOL ) or short take-off and vertical landing ( STOVL ) aircraft cannot perform without
3402-452: Is a type of rotorcraft in which lift and thrust are supplied by one or more horizontally-spinning rotors. By contrast the autogyro (or gyroplane) and gyrodyne have a free-spinning rotor for all or part of the flight envelope, relying on a separate thrust system to propel the craft forwards, so that the airflow sets the rotor spinning to provide lift. The compound helicopter also has a separate thrust system, but continues to supply power to
3528-758: Is being developed by General Dynamics Canada, as is the Sonobuoy Acoustic Processing System. The radar is a Telephonics APS-143B, the EO System a Flir Systems SAFIRE III, the sonar an L-3 HELRAS , and the ESM , a Lockheed Martin AN/ALQ-210. CMC Electronics provides the flight management system , named CMA-2082MH Aircraft Management System. The Canadian Forces were to take delivery of CH-148s beginning in November 2008. In April 2009
3654-698: Is being extended along the island's mountainous west coast. On the east coast, the East Coast Trail extends through the Avalon Peninsula for 220 km (140 mi), beginning near Fort Amherst in St. John's and ending in Cappahayden , with an additional 320 km (200 mi) of trail under construction. The Marble Mountain Ski Resort near Corner Brook is a major attraction in
3780-452: Is called an aerial crane . Aerial cranes are used to place heavy equipment, like radio transmission towers and large air conditioning units, on the tops of tall buildings, or when an item must be raised up in a remote area, such as a radio tower raised on the top of a hill or mountain. Helicopters are used as aerial cranes in the logging industry to lift trees out of terrain where vehicles cannot travel and where environmental concerns prohibit
3906-547: Is equipped to stabilize and provide limited medical treatment to a patient while in flight. The use of helicopters as air ambulances is often referred to as " MEDEVAC ", and patients are referred to as being "airlifted", or "medevaced". This use was pioneered in the Korean War , when time to reach a medical facility was reduced to three hours from the eight hours needed in World War II , and further reduced to two hours by

4032-522: Is known about them beyond archeological evidence of early settlements. Evidence of successive cultures have been found. The Late Paleo-Eskimo, or Dorset culture , settled there about 4,000 years ago. They were descendants of migrations of ancient prehistoric peoples across the High Arctic thousands of years ago, after crossing from Siberia via the Bering land bridge . The Dorset died off or abandoned
4158-466: Is low, though, less than 12% in the same 2003 study. The referendum campaign of 1948 was bitterly fought, and interests in both Canada and Britain favoured and supported confederation with Canada. Jack Pickersgill , a western Canadian native and politician, worked with the confederation camp during the campaign. The Catholic Church, whose members were a minority on the island, lobbied for continued independence. Canada offered financial incentives, including
4284-732: Is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait . It blocks the mouth of the Saint Lawrence River , creating the Gulf of Saint Lawrence , the world's largest estuary . Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon . With an area of 108,860 square kilometres (42,031 sq mi), Newfoundland
4410-678: Is the Sud-Ouest Djinn , and an example of the hot tip jet helicopter is the YH-32 Hornet . Some radio-controlled helicopters and smaller, helicopter-type unmanned aerial vehicles , use electric motors or motorcycle engines. Radio-controlled helicopters may also have piston engines that use fuels other than gasoline, such as nitromethane . Some turbine engines commonly used in helicopters can also use biodiesel instead of jet fuel. There are also human-powered helicopters . A helicopter has four flight control inputs. These are
4536-631: Is the world's 16th-largest island , Canada's fourth-largest island , and the largest Canadian island outside the North . The provincial capital, St. John's , is located on the southeastern coast of the island; Cape Spear , just south of the capital, is the easternmost point of North America , excluding Greenland. It is common to consider all directly neighbouring islands such as New World , Twillingate , Fogo and Bell Island to be 'part of Newfoundland' (i.e., distinct from Labrador). By that classification, Newfoundland and its associated small islands have
4662-530: Is the venue for large sporting and concert events in the province. In March, the annual seal hunt (of the harp seal ) takes place. Largest municipalities (2016 population) Newfoundland is roughly triangular, with each side being approximately 500 kilometres (310 mi), and having an area of 108,860 square kilometres (42,030 sq mi). Newfoundland and its associated small islands have a total area of 111,390 square kilometres (43,010 sq mi). Newfoundland extends between latitudes 46°36'N and 51°38'N. Newfoundland
4788-436: Is the youngest province in Canada. Newfoundland was organised as a colony in 1825, was self-governing from 1855 to 1934, but after a financial crisis the legislature was suspended and it was ruled through a Commission of Government (see Dominion of Newfoundland ). On June 22 and July 3, 1948, the population of the colony voted in referendums 52.3% to 47.7% in favour of joining Canada as a province. Opposition to confederation
4914-655: Is thought to have been an image of a green fir tree on a pink background that was in use in the early 19th century. The first official flag identifying Newfoundland, flown by vessels in service of the colonial government, was the Newfoundland Blue Ensign, adopted in 1870 and used until 1904, when it was modified slightly. In 1904, the crown of the Blue Ensign was replaced with the Great Seal of Newfoundland (having been given royal approval in 1827) and
5040-411: Is to control forward and back, right and left. The collective is used to maintain altitude. The pedals are used to control nose direction or heading . It is the interaction of these controls that makes hovering so difficult, since an adjustment in any one control requires an adjustment of the other two, creating a cycle of constant correction. As a helicopter moves from hover to forward flight it enters
5166-727: Is wider and has a larger diameter than the S-70 Blackhawk . The tapered blade tip sweeps back and angles downward to reduce noise and increase lift. Tethered hover flight has recorded 138 kN (31,000 lbf) of lift generated, both in and out of ground effect. Unlike the Sea King, but in common with almost all current production naval helicopters, the Cyclone is not amphibious and cannot float on water. A number of safety features such as flaw tolerance, bird strike capability and engine burst containment have been incorporated into

Most were in North America with 34.3% then in Europe with 28.0% followed by Asia-Pacific with 18.6%, Latin America with 11.6%, Africa with 5.3% and Middle East with 1.7%. The earliest references for vertical flight came from China. Since around 400 BC, Chinese children have played with bamboo flying toys (or Chinese top). This bamboo-copter is spun by rolling a stick attached to
5544-522: The Beothuk language , which is often considered to be a member of the Algonquian language family although the lack of sufficient records means that it is not possible to demonstrate such a connection confidently. The tribe is now typically considered extinct, but evidence of its culture is preserved in museums and historical and archaeological records. Shanawdithit , a woman who is often regarded as
5670-629: The Bishop of Newfoundland until a separate Bishop of Bermuda was created in 1919, though Newfoundland would become a Dominion in its own right from 1907 (the Dominion of Newfoundland ), before reverting to colonial status in 1934, and finally joining the Dominion of Canada in 1949 as the Province of Newfoundland . The European immigrants, mostly English, Scots, Irish and French, built a society in
5796-841: The Codroy Valley area, chiefly by settlers from Cape Breton Island , Nova Scotia. The Gaelic names reflected the association with fishing: in Scottish Gaelic , it was called Eilean a' Trosg , literally 'Island of the Cod '. Similarly, the Irish name Talamh an Éisc means 'Land of the Fish'. The first inhabitants of Newfoundland were the Paleo-Eskimo , who have no known link to other groups in Newfoundland history. Little
5922-527: The Cornu helicopter which used two 6.1-metre (20 ft) counter-rotating rotors driven by a 24 hp (18 kW) Antoinette engine. On 13 November 1907, it lifted its inventor to 0.3 metres (1 ft) and remained aloft for 20 seconds. Even though this flight did not surpass the flight of the Gyroplane No. 1, it was reported to be the first truly free flight with a pilot. Cornu's helicopter completed

The helicopter also performs utility and transport roles in support of national and international security efforts. In 2004, Canada awarded Sikorsky Aircraft a contract for 28 CH-148s with deliveries originally planned to start in 2009. Deliveries were repeatedly delayed due to development issues and difficulty fulfilling contract requirements;

All except the Newfoundland Colony and Bermuda confederated in 1867 to form the Dominion of Canada . Newfoundland and Bermuda would retain links (possibly explaining similarities between the Newfoundland English and Bermudian English ), including settlement in Newfoundland of Bermudians such as Joseph Outerbridge , especially their being grouped under
6300-499: The Vietnam War . In naval service a prime function of rescue helicopters is to promptly retrieve downed aircrew involved in crashes occurring upon launch or recovery aboard aircraft carriers. In past years this function was performed by destroyers escorting the carrier, but since then helicopters have proved vastly more effective. Police departments and other law enforcement agencies use helicopters to pursue suspects and patrol

#17327724542286552-404: The 17th century came Irish fishermen, who found so many fisheries that they named the island Talamh an Éisc , meaning 'Land of the Fish', more loosely 'the fishing grounds' in Irish. In 1583, when Sir Humphrey Gilbert formally claimed Newfoundland as a colony of England, he found numerous English, French and Portuguese vessels at St. John's. There was no permanent European population. Gilbert

The Mi'kmaq, Innu and Inuit all hunted and fished around Newfoundland but no evidence indicates that they lived on the island for long periods of time and would only travel to Newfoundland temporarily. Inuit have been documented on the Great Northern Peninsula as late as the 18th-Century. Newfoundland was historically

Sir George Cayley , influenced by a childhood fascination with the Chinese flying top, developed a model of feathers, similar to that of Launoy and Bienvenu, but powered by rubber bands. By the end of the century, he had progressed to using sheets of tin for rotor blades and springs for power. His writings on his experiments and models would become influential on future aviation pioneers. Alphonse Pénaud would later develop coaxial rotor model helicopter toys in 1870, also powered by rubber bands. One of these toys, given as
7686-478: The Chinese toy. It was not until the early 1480s, when Italian polymath Leonardo da Vinci created a design for a machine that could be described as an " aerial screw ", that any recorded advancement was made towards vertical flight. His notes suggested that he built small flying models, but there were no indications for any provision to stop the rotor from making the craft rotate. As scientific knowledge increased and became more accepted, people continued to pursue

Shearwater Heliport is the headquarters of 12 Wing, which were operating the CH-124 Sea King . Due to delays and export restrictions, the first 19 of the 28 CH-148 Cyclones were to be delivered in an interim standard which does not meet
8190-453: The Gyroplane No. 1 lifted its pilot into the air about 0.6 metres (2 ft) for a minute. The Gyroplane No. 1 proved to be extremely unsteady and required a man at each corner of the airframe to hold it steady. For this reason, the flights of the Gyroplane No. 1 are considered to be the first manned flight of a helicopter, but not a free or untethered flight. That same year, fellow French inventor Paul Cornu designed and built

8946-519: The Red and Blue Ensigns retained as ensigns for shipping identification. On March 31, 1949, Newfoundland became a province of Canada but retained the Union Jack in legislature, still designating it as the "national" flag. This was later reaffirmed by the Revised Statutes Act of 1952, and the Union Jack remained the official flag of Newfoundland until 1980, when it was replaced by the current provincial flag. (See Province of Newfoundland and Labrador for continued discussion of provincial flags.) As one of
9072-818: The United Kingdom declared the Colony of Newfoundland, as an independent Dominion within the British Empire , and from that point until 1965, the Newfoundland Red Ensign was used as the civil ensign of the Dominion of Newfoundland with the Blue Ensign, again, reserved for government shipping identification. In 1931 the Newfoundland National Assembly adopted the Union Jack as the official national flag, with
9198-550: The aircraft's handling properties under low airspeed conditions—it has proved advantageous to conduct tasks that were previously not possible with other aircraft, or were time- or work-intensive to accomplish on the ground. Today, helicopter uses include transportation of people and cargo, military uses, construction, firefighting, search and rescue , tourism , medical transport, law enforcement, agriculture, news and media , and aerial observation , among others. A helicopter used to carry loads connected to long cables or slings
9324-466: The aviation industry; and the turboshaft engine for helicopter use, pioneered in December 1951 by the aforementioned Kaman K-225, finally gave helicopters an engine with a large amount of power and a low weight penalty. Turboshafts are also more reliable than piston engines, especially when producing the sustained high levels of power required by a helicopter. The turboshaft engine was able to be scaled to
9450-435: The blades angle forwards or backwards, or left and right, to make the helicopter move in those directions. The anti-torque pedals are located in the same position as the rudder pedals in a fixed-wing aircraft, and serve a similar purpose, namely to control the direction in which the nose of the aircraft is pointed. Application of the pedal in a given direction changes the pitch of the tail rotor blades, increasing or reducing
9576-677: The building of roads. These operations are referred to as longline because of the long, single sling line used to carry the load. In military service helicopters are often useful for delivery of outsized slung loads that would not fit inside ordinary cargo aircraft: artillery pieces, large machinery (field radars, communications gear, electrical generators), or pallets of bulk cargo. In military operations these payloads are often delivered to remote locations made inaccessible by mountainous or riverine terrain, or naval vessels at sea. In electronic news gathering , helicopters have provided aerial views of some major news stories, and have been doing so, from
9702-424: The coast, the area available to the Beothuk to harvest the marine resources they relied upon was diminished. By the beginning of the 19th century, few Beothuk remained. Most died due to infectious diseases carried by Europeans, to which they had no immunity , and starvation. Government attempts to engage with the Beothuk and aid them came too late. The Beothuk did not have friendly relations with foreigners, unlike
9828-406: The cockpit from overhead. The control is called the cyclic because it changes cyclic pitch of the main blades. The result is to tilt the rotor disk in a particular direction, resulting in the helicopter moving in that direction. If the pilot pushes the cyclic forward, the rotor disk tilts forward, and the rotor produces a thrust in the forward direction. If the pilot pushes the cyclic to the side,
9954-470: The cyclic, the collective, the anti-torque pedals, and the throttle. The cyclic control is usually located between the pilot's legs and is commonly called the cyclic stick or just cyclic . On most helicopters, the cyclic is similar to a joystick. However, the Robinson R22 and Robinson R44 have a unique teetering bar cyclic control system and a few helicopters have a cyclic control that descends into
10080-429: The design. An active vibration system ensures comfortable flight and acoustic levels are well below certification requirements. The Cyclone will feature a modified main gearbox, which has been redesigned since a March 2009 accident. The CH-148 is equipped with devices to search and locate submarines during ASW, and is equipped with countermeasures to protect itself against missile strikes. The Integrated Mission System
10206-674: The early 2000s and another procurement competition was initiated. On 23 November 2004, Canada's Department of National Defence announced the award of a CA$ 1.8 billion contract to Sikorsky to produce 28 helicopters, with deliveries scheduled to start in January 2009. In addition, Sikorsky's subcontractors, General Dynamics Canada and L-3 MAS are responsible for in-service maintenance and the Maritime Helicopter Training Centre including two Operational Mission Simulators. Other elements of in-service support include
10332-483: The early 21st century, as well as recently weaponized utilities such as artillery spotting , aerial bombing and suicide attacks . The English word helicopter is adapted from the French word hélicoptère , coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix ( ἕλιξ ), genitive helikos (ἕλῐκος), "helix, spiral, whirl, convolution" and pteron ( πτερόν ) "wing". In
10458-439: The early years of the 19th century. The French name for the island is Terre-Neuve . The name Newfoundland is one of the oldest European place names in Canada in continuous geographical and cartographical use, dating from a 1502 letter. It was stated in the following 1628 poem: A Skeltonicall continued ryme, in praise of my New-found-Land After the 1783 independence of the thirteen continental colonies that became
10584-439: The event was taken by Max Skladanowsky , but it remains lost . In 1885, Thomas Edison was given US$ 1,000 (equivalent to $ 34,000 today) by James Gordon Bennett, Jr. , to conduct experiments towards developing flight. Edison built a helicopter and used the paper for a stock ticker to create guncotton , with which he attempted to power an internal combustion engine. The helicopter was damaged by explosions and one of his workers
10710-719: The first European since the Norse settlers to set foot on Newfoundland, working under commission of King Henry VII of England . His landing site is unknown but popularly believed to be Cape Bonavista , along the island's East coast. Another site claimed is Cape Bauld , at the tip of the Great Northern Peninsula . A document found in the Spanish National Archives, written by a Bristol merchant, reports that Cabot's crew landed 1,800 miles or 2,900 kilometres west of Dursey Head , Ireland (latitude 51°35′N), which would put Cabot within sight of Cape Bauld. This document mentions an island that Cabot sailed past to go ashore on
10836-476: The first deliveries, involving six initial helicopters (designated as Block 1), occurred during June 2015. Three years later, the Cyclone Block 2 achieved initial operating capability (IOC). The fleet was briefly grounded in early 2020 following a crash that was attributed to poor documentation and software flaws. Canada began to seek a replacement for the Sea King maritime helicopter in 1986 when it issued
10962-486: The first half of the 20th century was that the amount of power produced by an engine was not able to overcome the engine's weight in vertical flight. This was overcome in early successful helicopters by using the smallest engines available. When the compact, flat engine was developed, the helicopter industry found a lighter-weight powerplant easily adapted to small helicopters, although radial engines continued to be used for larger helicopters. Turbine engines revolutionized
11088-600: The first places in the New World where Europeans settled, Newfoundland also has a history of European colonization. St. John's is the oldest city in Canada and the oldest continuously settled location in English-speaking North America. The St. John's census metropolitan area includes 12 suburban communities, the largest of which are the city of Mount Pearl and the towns of Conception Bay South and Paradise . The province's third-largest city
11214-460: The high operating cost of helicopters cost-effective in ensuring that oil platforms continue to operate. Various companies specialize in this type of operation. NASA developed Ingenuity , a 1.8 kg (4.0 lb) helicopter used to survey Mars (along with a rover). It began service in February 2021 and was retired due to sustained rotor blade damage in January 2024 after 73 sorties. As
11340-480: The idea of vertical flight. In July 1754, Russian Mikhail Lomonosov had developed a small coaxial modeled after the Chinese top but powered by a wound-up spring device and demonstrated it to the Russian Academy of Sciences . It was powered by a spring, and was suggested as a method to lift meteorological instruments. In 1783, Christian de Launoy , and his mechanic , Bienvenu, used a coaxial version of
11466-504: The in-service and stored helicopter fleet of 38,570 with civil or government operators was led Robinson Helicopter with 24.7% followed by Airbus Helicopters with 24.4%, then Bell with 20.5 and Leonardo with 8.4%, Russian Helicopters with 7.7%, Sikorsky Aircraft with 7.2%, MD Helicopters with 3.4% and other with 2.2%. The most widespread model is the piston Robinson R44 with 5,600, then the H125/ AS350 with 3,600 units, followed by
11592-561: The island prior to the arrival of the Norse . After this period, the Beothuk settled in Newfoundland, migrating from Labrador on the mainland. There is no evidence that the Beothuk inhabited the island before Norse settlement. Scholars believe that the Beothuk are related closely to the Innu of Labrador. The tribe later was declared "extinct" although people of partial Beothuk descent have been documented. The name Beothuk meant 'people' in
11718-662: The lack of an airstrip would make transport via fixed-wing aircraft impossible. The use of transport helicopters to deliver troops as an attack force on an objective is referred to as " air assault ". Unmanned aerial systems (UAS) helicopter systems of varying sizes are developed by companies for military reconnaissance and surveillance duties. Naval forces also use helicopters equipped with dipping sonar for anti-submarine warfare , since they can operate from small ships. Oil companies charter helicopters to move workers and parts quickly to remote drilling sites located at sea or in remote locations. The speed advantage over boats makes
11844-564: The last full-blood Beothuk, died in St. John's in 1829 of tuberculosis . However, Santu Toney, born around 1835 and died in 1910, was a woman of mixed Mi'kmaq and Beothuk descent, meaning some Beothuk must have lived on beyond 1829. She described her father as Beothuk and mother as Mi'kmaq, both from Newfoundland. The Beothuk may have intermingled and assimilated with Innu in Labrador and Mi'kmaq in Newfoundland. European histories also suggest potential historical competition and hostility between
11970-581: The late 1960s. Helicopters have also been used in films, both in front and behind the camera. The largest single non-combat helicopter operation in history was the disaster management operation following the 1986 Chernobyl nuclear disaster . Hundreds of pilots were involved in airdrop and observation missions, making dozens of sorties a day for several months. " Helitack " is the use of helicopters to combat wildland fires . The helicopters are used for aerial firefighting (water bombing) and may be fitted with tanks or carry helibuckets . Helibuckets, such as
12096-555: The limited power did not allow for manned flight. The introduction of the internal combustion engine at the end of the 19th century became the watershed for helicopter development as engines began to be developed and produced that were powerful enough to allow for helicopters able to lift humans. Early helicopter designs utilized custom-built engines or rotary engines designed for airplanes, but these were soon replaced by more powerful automobile engines and radial engines . The single, most-limiting factor of helicopter development during
12222-549: The mainland. This description fits with the Cape Bauld theory, as Belle Isle is not far offshore. After Cabot, the first European visitors to Newfoundland were Portuguese, Spanish, Basque, French and English migratory fishermen. In 1501, Portuguese explorers Gaspar Corte-Real and his brother Miguel Corte-Real charted part of the coast of Newfoundland in a failed attempt to find the Northwest Passage . Late in
12348-485: The monorotor design, and coaxial-rotor , tiltrotor and compound helicopters are also all flying today. Four-rotor helicopters ( quadcopters ) were pioneered as early as 1907 in France, and along with other types of multicopters , have been developed mainly for specialized applications such as commercial unmanned aerial vehicles (drones) due to the rapid expansion of drone racing and aerial photography markets in
12474-601: The nearby park, the Parco Forlanini. Emmanuel Dieuaide's steam-powered design featured counter-rotating rotors powered through a hose from a boiler on the ground. In 1887 Parisian inventor, Gustave Trouvé , built and flew a tethered electric model helicopter. In July 1901, the maiden flight of Hermann Ganswindt 's helicopter took place in Berlin-Schöneberg; this was probably the first heavier-than-air motor-driven flight carrying humans. A movie covering
12600-464: The nose to pitch down, with a resultant increase in airspeed and loss of altitude. Aft cyclic will cause the nose to pitch up, slowing the helicopter and causing it to climb. Increasing collective (power) while maintaining a constant airspeed will induce a climb while decreasing collective will cause a descent. Coordinating these two inputs, down collective plus aft cyclic or up collective plus forward cyclic, will result in airspeed changes while maintaining
12726-399: The original RFQ and one of 7 concessions made to Sikorsky. The Canadian government stated that these concessions would not affect the safety of Armed Forces personnel. However, oil loss in the main gearbox followed by several other factors caused the 2009 crash of a S-92 , a civil version of the helicopter, off the coast of Newfoundland . Sikorsky added an oil cooler bypass switch and stated
12852-525: The original contract requirements. This allows operational testing and training to begin before the end of the year. In March 2010, the first CH-148 was embarked on HMCS Montréal for an intensive open seas trials including landing and takeoff. In June 2010, Sikorsky announced the Canadian Forces would receive six interim CH-148 Cyclones in November 2010. In July 2010, Sikorsky reached an agreement on delay payments and deliveries; deliveries of
12978-411: The power normally required to be diverted for the tail rotor to be applied fully to the main rotors, increasing the aircraft's power efficiency and lifting capacity. There are several common configurations that use the counter-rotating effect to benefit the rotorcraft: Tip jet designs let the rotor push itself through the air and avoid generating torque. The number, size and type of engine(s) used on
13104-471: The program, and restrictions from US government International Traffic in Arms Regulations delayed initial aircraft deliveries until 2010. Further delays resulted in expected delivery pushed to 2015. In 2013 Canada rejected the delivery of "interim" helicopters offered by Sikorsky that lacked critical mission systems. In September 2013, the Canadian government announced that they were reevaluating
13230-607: The remaining CH-148s with full capabilities were to begin in June 2012. All interim-standard helicopters were to be retrofitted by December 2013. On 22 February 2011, the Office of the Prime Minister of Canada announced the proposed arrival of nine Cyclones on Canada's west coast in the spring of 2014. By March 2011 the six interim CH-148s had not been delivered. On 3 March 2011, the federal government announced that it would impose
13356-436: The rotor disk tilts to that side and produces thrust in that direction, causing the helicopter to hover sideways. The collective pitch control or collective is located on the left side of the pilot's seat with a settable friction control to prevent inadvertent movement. The collective changes the pitch angle of all the main rotor blades collectively (i.e. all at the same time) and independently of their position. Therefore, if
13482-406: The rotor in cruise, which allows its rotation to be slowed down , thus increasing the maximum speed of the aircraft. The Lockheed AH-56A Cheyenne diverted up to 90% of its engine power to a pusher propeller during forward flight. There are three basic flight conditions for a helicopter: hover, forward flight and the transition between the two. Hovering is the most challenging part of flying
13608-422: The rotor throughout normal flight. The rotor system, or more simply rotor , is the rotating part of a helicopter that generates lift . A rotor system may be mounted horizontally, as main rotors are, providing lift vertically, or it may be mounted vertically, such as a tail rotor, to provide horizontal thrust to counteract torque from the main rotors. The rotor consists of a mast, hub and rotor blades. The mast
13734-418: The size of the helicopter being designed, so that all but the lightest of helicopter models are powered by turbine engines today. Special jet engines developed to drive the rotor from the rotor tips are referred to as tip jets . Tip jets powered by a remote compressor are referred to as cold tip jets, while those powered by combustion exhaust are referred to as hot tip jets. An example of a cold jet helicopter
13860-483: The skies. Since helicopters can achieve a unique aerial view, they are often used in conjunction with police on the ground to report on suspects' locations and movements. They are often mounted with lighting and heat-sensing equipment for night pursuits. Military forces use attack helicopters to conduct aerial attacks on ground targets. Such helicopters are mounted with missile launchers and miniguns . Transport helicopters are used to ferry troops and supplies where
13986-632: The southernmost part of the Inuit's territorial range. When Europeans arrived from 1497 and later, starting with John Cabot , they established contact with the Beothuk. Estimates of the number of Beothuk on the island at this time vary, typically around 700. Later both the English and French settled the island. They were followed by the Mi'kmaq , an Algonquian -speaking indigenous people from eastern Canada and present-day Nova Scotia. As European and Mi'kmaq settlement became year-round and expanded to new areas of
14112-479: The tail rotor, such as the ducted fan (called Fenestron or FANTAIL ) and NOTAR . NOTAR provides anti-torque similar to the way a wing develops lift through the use of the Coandă effect on the tail boom. The use of two or more horizontal rotors turning in opposite directions is another configuration used to counteract the effects of torque on the aircraft without relying on an anti-torque tail rotor. This allows
14238-448: The throttle is to maintain enough engine power to keep the rotor RPM within allowable limits so that the rotor produces enough lift for flight. In single-engine helicopters, the throttle control is a motorcycle-style twist grip mounted on the collective control, while dual-engine helicopters have a power lever for each engine. A compound helicopter has an additional system for thrust and, typically, small stub fixed wings . This offloads
14364-417: The thrust produced by the tail rotor and causing the nose to yaw in the direction of the applied pedal. The pedals mechanically change the pitch of the tail rotor altering the amount of thrust produced. Helicopter rotors are designed to operate in a narrow range of RPM . The throttle controls the power produced by the engine, which is connected to the rotor by a fixed ratio transmission. The purpose of
14490-520: The top of a trench. The next morning, only 68 men answered the roll-call. Even now, when the rest of Canada celebrates the founding of the country on July 1, many Newfoundlanders take part in solemn ceremonies of remembrance. The Second World War also had a lasting effect on Newfoundland. In particular, the United States assigned forces to the military bases at Argentia, Gander, Stephenville, Goose Bay, and St. John's. Newfoundland and Labrador
14616-573: The verge of cancellation with the Canadian government ordering a possible change to the maritime helicopter requirements. In June 2015, it was reported that Sikorsky was ready to begin deliveries of the first interim Cyclones to the Royal Canadian Air Force. Six helicopters were delivered on 19 June 2015, and two "Block 1.1" Cyclones were delivered in November–December 2015. These eight helicopters will allow for RCAF training on
14742-517: The vertical flight he had envisioned. Steam power was popular with other inventors as well. In 1877, the Italian engineer, inventor and aeronautical pioneer Enrico Forlanini developed an unmanned helicopter powered by a steam engine . It rose to a height of 13 meters (43 feet), where it remained for 20 seconds, after a vertical take-off from a park in Milan . Milan has dedicated its city airport to Enrico Forlanini, also named Linate Airport , as well as
14868-467: The very earliest modern European population on the island. By 1620, the fishermen of England's West Country dominated the east coast of Newfoundland. French fishermen dominated the island's south coast and Northern Peninsula. The decline of the fisheries, the wasting of the shoreline forests, and an overstocking of liquor by local merchants influenced the Whitehall government in 1675 to decline to set up
14994-857: The winter for skiers in eastern Canada. Other major communities include the following towns: Educational institutions include the provincial university, Memorial University of Newfoundland whose main campus is situated in St. John's, along with the Grenfell Campus in Corner Brook, in addition to the College of the North Atlantic based in Stephenville and other communities. Bonavista , Placentia and Ferryland are all historic locations for various early European settlement or discovery activities. Tilting Harbour on Fogo Island
15120-491: Was an Irish Catholic fisherman who permanently settled in Newfoundland. He established the fishing town of Branch . He and his cousin Father Patrick Power of Callan , County Kilkenny, spread Catholicism in Newfoundland. This settlement attracted a major migration of Irish Catholic immigrants to Newfoundland in the early eighteenth century. By the late 18th century, permanent settlement increased, peaking in
15246-486: Was badly burned. Edison reported that it would take a motor with a ratio of three to four pounds per horsepower produced to be successful, based on his experiments. Ján Bahýľ , a Slovak inventor, adapted the internal combustion engine to power his helicopter model that reached a height of 0.5 meters (1.6 feet) in 1901. On 5 May 1905, his helicopter reached 4 meters (13 feet) in altitude and flew for over 1,500 meters (4,900 feet). In 1908, Edison patented his own design for
15372-568: Was by the Norse who built a temporary base at L'Anse aux Meadows , a Norse settlement near the northernmost tip of Newfoundland (Cape Norman), which has been dated to be approximately 1000 years old. The site is considered the only undisputed evidence of Pre-Columbian contact between the Old and New Worlds if the Norse– Inuit contact on Greenland is not counted. The next European visitors to Newfoundland were Portuguese and French fishermen. The island
15498-477: Was concentrated among residents of the capital St. John's and its surrounding hinterland on the Avalon Peninsula. Newfoundland joined Canada at one minute before midnight on March 31, 1949. Union with Canada has done little to reduce Newfoundlanders' self-image as a distinctive group. In 2003, 72% of residents responding identified first as Newfoundlanders, secondarily as Canadians. Separatist sentiment
15624-507: Was lost at sea during his return voyage, and plans of settlement were postponed. In July 1596 the Scottish vessel the "William" left Aberdeen for "new fund land" (Newfoundland) and returned in 1600. On 5 July 1610, John Guy set sail from Bristol , England, with 39 other colonists for Cuper's Cove . This, and other early attempts at permanent settlement failed to make a profit for the English investors, but some settlers remained, forming
15750-557: Was possibly visited by the Venetian navigator John Cabot (Giovanni Caboto), working under contract to Henry VII of England on his expedition from Bristol in 1497. In 1501 Portuguese brothers Gaspar Corte-Real and Miguel Corte-Real charted part of the coast of Newfoundland in an attempt to find the Northwest Passage . On 5 August 1583, Humphrey Gilbert claimed Newfoundland as England's first overseas colony under Royal Charter of Queen Elizabeth I , thus officially establishing
15876-453: Was spread widely around a rugged coastline in small outport settlements. Many were distant from larger centres of population and isolated for long periods by winter ice or bad weather. These conditions had an effect on the cultures of the immigrants. They generated new ways of thinking and acting. Newfoundland and Labrador developed a wide variety of distinctive customs, beliefs, stories, songs and dialects. A unique vocabulary arose focused on
