Vickers Vendace
The Vickers Vendace was a 1920s British trainer aircraft. It was originally designed as a floatplane trainer for the Royal Air Force. Background In October 1924, the British Air Ministry issued Specification 5A/24 for a floatplane trainer. To meet this requirement, Vickers designed a two-seat biplane, the Vickers Type 120 Vendace I. In August 1925, the Air Ministry placed an order for a single prototype, in addition to competing aircraft from Parnall and Blackburn, (the Parnall Perch and Blackburn Sprat).Andrews and Morgan 1988, p. 194Jackson 1968, p. 233 Design and development The Vendace I was a two-bay biplane with folding wooden wings and a steel tube fuselage, powered by a Rolls-Royce Falcon engine. Its undercarriage could be changed from floats to wheels in ten minutes, while its fuel supply was held in two streamlined tanks above the upper wing. The first Vendace first flew at Brooklands by March 1926, and then underwent successful trials as a landplane, including o ...

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 ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Military Aircraft Serials
United Kingdom military aircraft serial numbers are aircraft registration numbers used to identify individual military aircraft in the United Kingdom (UK). All UK military aircraft are allocated and display a unique registration number. A unified registration number system, maintained initially by the Air Ministry (AM), and its successor the Ministry of Defence (MoD), is used for aircraft operated by the Royal Air Force (RAF), Fleet Air Arm (FAA), and Army Air Corps (AAC). Military aircraft operated by government agencies and civilian contractors (for example QinetiQ) are also assigned registration numbers from this system. When the Royal Flying Corps (RFC) was formed in 1912, its aircraft were identified by a letter/number system related to the manufacturer. The prefix 'A' was allocated to balloons of No.1 Company, Air Battalion, Royal Engineers, the prefix 'B' to aeroplanes of No.2 Company, and the prefix 'F' to aeroplanes of the Central Flying School.Bruce 1956, p.922 ...

Hispano-Suiza 8
The Hispano-Suiza 8 was a water-cooled V8 SOHC aero engine introduced by Hispano-Suiza in 1914, and was the most commonly used liquid-cooled engine in the aircraft of the Entente Powers during the First World War. The original Hispano-Suiza 8A was rated at and the later, larger displacement Hispano-Suiza 8F reached . Hispano-Suiza 8 engines and variants produced by Hispano-Suiza and other companies under licence were built in twenty-one factories in Spain, France, Britain, Italy, and the U.S. Derivatives of the engine were also used abroad to power numerous aircraft types and the engine can be considered as the ancestor of another successful engine by the same designer, the Hispano-Suiza 12Y (and Soviet Klimov V12 derivative aero-engines) which was in service during the Second World War. Design and development Origins At the beginning of World War I, the production lines of the Barcelona based Hispano-Suiza automobile and engine company were switched to the production of ...

Aircraft Operating Company
The Aircraft Operating Company was a British aerial photography company, that took over Aerofilms in 1925. In 1940, its staff and equipment were requisitioned by the Air Ministry, and in 1944 the company itself was taken over by Hunting Aerosurveys. History The Aircraft Operating Company Ltd (AOC) was founded by Harold Hemming AFC (also known as Major 'Lemnos' Hemming), a former Royal Flying Corps pilot, aerial survey pilot and amateur air racing pilot. Hemming was managing director, and his business partner Alan S. Butler was chairman of the board. In 1925, AOC took over Aerofilms Ltd, and continued to employ Francis L. Wills as managing director of that company, that expanded its operations based at Hendon. In 1925, Ordnance Survey awarded to AOC the first contracts for the development of aerial photography in the production of its surveying and map-making operations. Throughout the 1920s and 1930s, AOC was employed by Ordnance Survey for surveying in many British overseas c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siddeley Puma
The Siddeley Puma was a British aero engine developed towards the end of World War I and produced by Siddeley-Deasy. The first engines left the production lines of Siddeley-Deasy in Coventry in August 1917, production continued until December 1918. At least 4,288 of the 11,500 ordered engines were delivered, orders were cancelled following the Armistice with Germany (Compiègne), Armistice. Production was continued under the name Armstrong Siddeley Puma when the manufacturer was bought by Armstrong Whitworth and became Armstrong Siddeley. The engine was based on a previous Beardmore Halford Pullinger, B.H.P engine which was also developed as the Galloway "Adriatic." Applications *The Puma engine was used in the British World War I bomber aircraft, the Airco D.H.9. In use it proved to be highly troublesome, making the aircraft significantly inferior to the type it replaced. The engine was also installed untidily, with the cylinder heads protruding. The D.H.9, as a type, was impr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ADC Nimbus
The ADC Nimbus was a British inline aero engine that first ran in 1926. The Nimbus was developed from the Siddeley Puma aero engine by Frank Halford of the Aircraft Disposal Company, the goal was to develop the Puma to produce its intended power output which Halford eventually achieved. The Nimbus was further developed into an air-cooled version known as the ADC Airsix which did not enter production and was not flown.Lumsden 2003, p. 55.
