Westland Dragonfly
The Westland WS-51 Dragonfly helicopter was built by Westland Aircraft and was an Anglicised licence-built version of the American Sikorsky S-51. Design and development On 19 January 1947 an agreement was signed between Westland Aircraft and Sikorsky to allow a British version of the S-51 to be manufactured under licence in the United Kingdom. These would be powered by the 500 hp Alvis Leonides radial engine. A modified version was also developed by Westland as the Westland Widgeon, but it was commercially unsuccessful. After delays caused by the need to modify and convert American-drawings to reflect British-sourced items and to replace the engine with a British-built Alvis Leonides 50, the prototype was first flown from Yeovil on 5 October 1948 piloted by Alan Bristow. Only 16 months had elapsed since work had begun on building the prototype registered G-AKTW. After evaluation initial orders for the British military were placed, thirteen Dragonfly HR.1s for the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Westland Whirlwind (helicopter)
The Westland Whirlwind helicopter was a British licence-built version of the U.S. Sikorsky S-55/H-19 Chickasaw. It primarily served with the Royal Navy's Fleet Air Arm in anti-submarine and search and rescue roles. Design and development In 1950, Westland Aircraft, already building the American Sikorsky S-51 under licence as the Westland Dragonfly, purchased the rights to manufacture and sell Sikorsky's larger Sikorsky S-55 helicopter. While a Sikorsky-built pattern aircraft was flown by Westland in June 1951, converting the design to meet British standards (including the provision of a revised main-rotor gearbox), was time consuming,James 1991, pp.320–321. and the first prototype British aircraft, registered ''G-AMJT'', powered by the 600 hp Pratt & Whitney R-1340-40 Wasp did not fly until August 1953.James 1991, p.322. This was followed by ten Whirlwind HAR.1s, which entered service shortly afterwards. They served in non-combat roles, including search and rescue ...

Casualty Evacuation
Casualty evacuation, also known as CASEVAC or by the callsign Dustoff or colloquially Dust Off, is a military term for the emergency patient evacuation of casualties from a combat zone. Casevac can be done by both ground and air. "DUSTOFF" is the callsign specific to U.S. Army Air Ambulance units. CASEVACs by air today are almost exclusively done by helicopter, a practice begun on a small scale toward the end of World War II; before that, STOL aircraft, such as the Fieseler Fi 156 or Piper J-3 were used. The primary difference between a CASEVAC and a medical evacuation (MEDEVAC) is that a MEDEVAC uses a standardized and dedicated vehicle providing en route care, while a CASEVAC uses non-standardized and non-dedicated vehicles that may or may not provide en route care. CASEVACs are commonly referred to as "a lift/flight of opportunity". If a corpsman/medic on the ground calls for a CASEVAC, the closest available unit with space could be called to assist, regardless of its me ...

Iraqi Air Force
The Iraqi Air Force (IQAF or IrAF) ( ar, القوات الجوية العراقية, Al Quwwat al Jawwiyah al Iraqiyyah}) is the aerial warfare service branch of the Iraqi Armed Forces. It is responsible for the defense of Iraqi airspace as well as the policing of its international borders. The IQAF also acts as a support force for the Iraqi Navy and the Iraqi Army, which allows Iraq to rapidly deploy its military. It is headquartered in Baghdad; the current commander is Gen. Shihab Jahid Ali. The Iraqi Air Force was founded in 1931, during the period of British control in Iraq after their defeat of the Ottomans in the First World War, with only a few pilots. The Iraqi Air Force operated mostly British aircraft until the 14 July Revolution in 1958, when the new Iraqi government began increased diplomatic relationships with the Soviet Union. The air force used both Soviet and British aircraft throughout the 1950s and 1960s. When Saddam Hussein came to power in 1979, the air force ...

Pratt & Whitney R-985
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a bore and stroke of , giving a 27% lesser total displacement. The Wasp Junior used ...

Fairey Aviation
The Fairey Aviation Company Limited was a British aircraft manufacturer of the first half of the 20th century based in Hayes in Middlesex and Heaton Chapel and RAF Ringway in Cheshire. Notable for the design of a number of important military aircraft, including the Fairey III family, the Swordfish, Firefly, and Gannet, it had a strong presence in the supply of naval aircraft, and also built bombers for the RAF. After World War II the company diversified into mechanical engineering and boat-building. The aircraft manufacturing arm was taken over by Westland Aircraft in 1960. Following a series of mergers and takeovers, the principal successor businesses to the company now trade as FBM Babcock Marine Ltd, Spectris plc, and WFEL (formerly Williams Fairey Engineering Limited), the latter manufacturing portable bridges.

Silver City Airways
Silver City Airways was an airline, based in the United Kingdom, that operated mainly in Europe, between 1946 and 1962. Unlike many airlines at the time, it was independent of government-owned corporations; its parent company was Zinc Corporation, an Australian company involved mainly in mining and mineral processing. The name "Silver City" originated as a nickname of Broken Hill, Australia – an area famed for silver mines, including some owned by the airline's parent company. The first commercial flight by Silver City departed London Heathrow for Sydney via Johannesburg in late 1946. The following year, Silver City leased its first Bristol Freighter, moved its base to Blackbushe and participated in the airlift of Hindu and Muslim refugees between Pakistan and India.''Aircraft (Gone but not forgotten ...
