Fairey FB-1 Gyrodyne
The Fairey FB-1 Gyrodyne is an experimental British rotorcraft that used single lifting rotor and a tractor propeller mounted on the tip of the starboard stub wing to provide both propulsion and anti-torque reaction. Design and development In April 1946, Fairey announced a private-venture project for a rotary-wing aircraft, to be built to a design developed by Dr. J.A.J. Bennett while he was chief technical officer at the Cierva Autogiro Company in 1936–1939. The Gyrodyne, constituting a third distinct type of rotorcraft and designated C.41 by the Cierva Autogiro Company, was in 1938 successfully tendered to the Royal Navy in response to Specification S.22/38 for a naval helicopter. Though preliminary work started on the project, it was abandoned with the outbreak of the Second World War, and G & J Weir, Ltd., the financiers of the Cierva Autogiro Company, declined to undertake further development in addition to their successful experiments with the W.5 and W.6 later ...

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 522/2
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 ...

Jet Gyrodyne
The Fairey Jet Gyrodyne is a British experimental compound gyroplane built by the Fairey Aviation Company that incorporated helicopter, gyrodyne and autogyro characteristics. The Jet Gyrodyne was the subject of a Ministry of Supply (MoS) research contract to gather data for the follow-up design, the Rotodyne. Design and development The Jet Gyrodyne was a modification of the second prototype FB-1 Gyrodyne aircraft registered ''G-AJJP''. The Jet Gyrodyne was built specifically to develop the pressure-jet rotor drive system and operational procedures used on the later Rotodyne. The Jet Gyrodyne utilised the fuselage, undercarriage and engine of the FB-1 Gyrodyne. The Alvis Leonides nine-cylinder radial engine was situated in the middle of the fuselage and drove a pusher propeller at the tip of each stub wing and two Rolls-Royce Merlin engine superchargers. The original three-blade tilting hub rotor system was replaced by a two-blade rotor controlled with swashplate-actuated cy ...

Bristol Sycamore
The Bristol Type 171 Sycamore was an early helicopter developed and built by the helicopter division of the Bristol Aeroplane Company. The name refers to the seeds of the sycamore tree, '' Acer pseudoplatanus'', which fall with a rotating motion. It has the distinction of being the first British helicopter to receive a certificate of airworthiness, as well as being the first British-designed helicopter to be introduced by and to serve with the Royal Air Force (RAF). Typically capable of seating up to three passengers, the type was often used as a transport for both passengers and cargo alike. In RAF service, the Sycamore was normally used in the search and rescue and casualty evacuation roles. The type proved the value of rotorcraft to easily traverse inhospitable or otherwise inaccessible terrain; the Sycamore made valuable contributions to British military activities during the Malayan Emergency, the Cyprus Emergency, and the Aden Emergency, in addition to other operations. ...

Westland WS-51 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 Roy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malayan Emergency
The Malayan Emergency, also known as the Anti–British National Liberation War was a guerrilla war fought in British Malaya between communist pro-independence fighters of the Malayan National Liberation Army (MNLA) and the military forces of the British Empire and Commonwealth. The communists fought to win independence for Malaya from the British Empire and to establish a socialist economy, while the Commonwealth forces fought to combat communism and protect British economic and colonial interests.Siver, Christi L. "The other forgotten war: understanding atrocities during the Malayan Emergency." In APSA 2009 Toronto Meeting Paper. 2009., p.36 The conflict was called the "Anti–British National Liberation War" by the MNLA, but an "Emergency" by the British, as London-based insurers would not have paid out in instances of civil wars. On 17 June 1948, Britain declared a state of emergency in Malaya following attacks on plantations, which in turn were revenge attacks for the ...

British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
