Westland Widgeon (helicopter)
The Westland Widgeon was a helicopter developed by Westland Aircraft as a private venture improvement on the Westland WS-51 Dragonfly. Design and development Westland Aircraft decided to make a private venture improvement on the Westland WS-51 Dragonfly helicopter, which was a licensed Sikorsky Aircraft design, by increasing the cabin capacity and replacing the Dragonfly's rotor head, blades and gearbox with the units used in the Westland Whirlwind. Three Dragonfly Series 1As were converted to WS-51 Series 2 Widgeon specifications and the first one flew on 23 August 1955. One of these conversions, registration G-ANLW, was the first helicopter to land at the London Heliport on 8 April 1959, and later appeared in the 1971 film, ''When Eight Bells Toll''. In 1957, there was a plan to take up to 24 existing Fleet Air Arm Dragonflies to Dragonfly HC.7 standard (as the Naval Widgeon was to become) but this was abandoned and it contributed to the decision to stop progress.

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 ...

Alvis Leonides 521/1
The Alvis Leonides was a British air-cooled nine-cylinder radial aero engine first developed by Alvis Car and Engineering Company in 1936. Design and development Development of the nine-cylinder engine was led by Capt. George Thomas Smith-Clarke. The prototype engine, called 9ARS and which weighed 693 lb and developed 450 hp, was run in December 1936. In 1938 Airspeed (1934) Ltd lent their test pilot, George Errington, and their much rebuilt Bristol Bulldog (''K3183''), to carry out test flights. Development was continued at a reduced pace during the Second World War and following testing in an Airspeed Oxford and an Airspeed Consul (''VX587''). Alvis was ready to market the engine in 1947 as the Series 500 (502, 503 and sub-types) for aeroplanes and Series 520 for helicopters. (Most helicopter engines were direct drive — no reduction gearbox — with a centrifugal clutch and fan cooling). The first production use was the Percival Prince, which flew in Jul ...

Bristow Helicopters
Bristow Helicopters Limited is a British civil helicopter operator originally based at Aberdeen Airport, Scotland, which is currently a part of the U.S.-based Bristow Group (, S&P 600 component) which in turn has its corporate headquarters in Houston, Texas, U.S. In 2020, Bristow Group was merged with Era Helicopters, a large U.S.-based commercial helicopter operator that was previously a division of Era Aviation, with the two companies then continuing to use the Bristow name. Bristow Helicopters was established by Alan Bristow in June 1955; two years later, it acquired its first pair of helicopters in the form of the Westland Widgeon. The company quickly expanded overseas as well as various services, including helicopter training, oil exploration, search and rescue, and charter flights. Having entered the African market in 1960, Nigeria became Bristow's biggest profit centre during the 1970s. Entering the North Sea market, also during the 1960s, Bristow became Aberdeen Airp ...

Biafran War
The Nigerian Civil War (6 July 1967 – 15 January 1970), also known as the Nigerian–Biafran War or the Biafran War, was a civil war fought between Nigeria and the Republic of Biafra, a secessionist state which had declared its independence from Nigeria in 1967. Nigeria was led by General Yakubu Gowon, while Biafra was led by Lieutenant Colonel Chukwuemeka "Emeka" Odumegwu Ojukwu. Biafra represented the nationalist aspirations of the Igbo ethnic group, whose leadership felt they could no longer coexist with the federal government dominated by the interests of the Muslim Hausa-Fulanis of Northern Nigeria. The conflict resulted from political, economic, ethnic, cultural and religious tensions which preceded the United Kingdom's formal decolonization of Nigeria from 1960 to 1963. Immediate causes of the war in 1966 included a military coup, a counter-coup, and anti-Igbo pogroms in Northern Nigeria. Control over the lucrative oil production in the Niger Delta also played a vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigerian Air Force
The Nigerian Air Force (NAF) is the air branch of the Nigerian Armed Forces. It is the youngest branch of the Nigerian Armed Forces. It is one of the largest in Africa, consisting of about 15,000 personnel and aircraft including eight Chinese Chengdu F-7s, 12 Dassault-Dornier Alpha Jets, three JF-17 Thunder Block II and 12 Super Tucano aircraft, 24 M-346 FAs on order, Helicopter gunships, armed attack drones, and military transport aircraft. History Although an Air Force was originally proposed in 1958, many lawmakers preferred to rely on the United Kingdom for air defense. But during peacekeeping operations in Congo and Tanganyika, the Nigerian Army had no air transport of its own, and so in 1962, the government began to recruit cadets for pilot training in various foreign countries, with the first ten being taught by the Egyptian Air Force. 1960s The Nigerian Air Force was formally established on 18 April 1964 with the passage of the Air Force Act 1964 by the National Ass ...

Royal Jordanian Air Force
The Royal Jordanian Air Force (RJAF; ar, سلاح الجو الملكي الأردني, Silāḥ ul-Jawu al-Malakī 'al-Urdunī) is the aerial warfare branch of the Jordanian Armed Forces. History Early days Jordan gained independence in 1946, but its first air bases had been set up in 1931 by the Royal Air Force. By 1948, Jordan began to develop a small air arm which came to be known as the Arab Legion Air Force (ALAF). The Royal Air Force assisted in training this small air arm and provided equipment. The ALAF's primary fighter was the de Havilland Vampire and a Vickers VC.1 Viking was operated as a VIP aircraft for use by the King of Jordan. By 1955 King Hussein realized the need for Jordan to have a more modern air force, and on 25 September 1955 the RJAF was established. By 1958 the Royal Air Force had left Jordan and the RJAF had taken control of the airfields in the country. 1960s In 1967, in the Six-Day War, the Israeli Air Force relentlessly attacked Jordan's Air ...

Royal Hong Kong Auxiliary Air Force
The Royal Hong Kong Auxiliary Air Force (RHKAAF) was a Hong Kong Government department based in Hong Kong. It was formed as an air force in 1949 as part of the Hong Kong Defence Force. In preparation for the transfer of sovereignty from the United Kingdom to the People's Republic of China, the Unit was disbanded on 31 March 1993. History The history of the Unit goes way back to the early days of Hong Kong as a British colony. On 30 May 1854, with the departure from Hong Kong of the British men-of-war on anti-piracy duties in the north, following the Shanghai precedent, an appeal was made by the Lieutenant-Governor, Sir William Caine, for willing citizens to assemble for the purpose of forming an auxiliary police force to protect the lives and property of Hong Kong’s inhabitants. Ninety-nine worthy men turned up and the Hong Kong Volunteer Corps was formed. Following numerous incarnations, the Royal Hong Kong Regiment (The Volunteers) and the Royal Hong Kong Auxiliary Air Force ...
