Miles Hawk
The Miles M.2 Hawk was a twin-seat light monoplane designed and produced by the British aircraft manufacturer Miles Aircraft Limited during the 1930s. It is the first of the company's aircraft to attain quantity production. The Hawk's development started in 1932 following a conversation between designer F.G. Miles and Charles Powis, the latter offering Miles hangar space at Woodley Aerodrome to build his proposed affordable twin-seat monoplane. The aircraft was designed by Miles and his wife, while construction of the prototype was mostly performed by the carpenter Harry Hull. On 29 March 1933, the prototype performed its maiden flight. The aircraft quickly proved its performance to be roughly 50 per cent greater than biplane contemporaries. Within 15 months, 47 Hawks had been sold to various domestic customers. An advanced derivative, the Miles Hawk Major, was also quickly developed, alongside several specialised versions of the original aircraft. Amongst other uses, the Haw ...

Miles Aircraft
Miles was the name used for aircraft and associated businesses of British engineer Frederick George Miles, who, with his wife – aviator and draughtswoman Maxine Blossom Miles, Maxine "Blossom" Miles (née Forbes-Robertson) – and his brother George Herbert Miles, designed numerous light civil and military aircraft and a range of curious prototypes, primarily between 1943 and 1947. History Phillips and Powis A company was founded in 1928 by Charles Powis and Jack Phillips as Phillips & Powis Aircraft (Reading) Ltd. In 1929 they opened Woodley Aerodrome, near the town of Reading, Berkshire, Reading, Berkshire. In 1936, Rolls-Royce Limited, Rolls-Royce bought into the company. Although aircraft were produced under the Miles name, it was not until 1943 that the firm became Miles Aircraft Limited when Rolls-Royce's interests were bought out. The company needed to increase production of the Miles Messenger and to do so it took over a former linen mill in Banbridge, County Dow ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the sou ...

1930s British Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

González Gil-Pazó GP-1
The González Gil-Pazó GP-1 was a single-engine, two-seat open cockpit training aircraft, built in Spain in the 1930s to compete for a government contract. Declared the winner, production was curtailed by the Spanish Civil War. Two cabin variants, the González Gil-Pazó GP-2 and GP-4, were also built. Design and development The first aircraft produced from the collaboration between Arturo González Gil y Santibañez and José Pazó was the Gil-Pazó No.1. It was, like all of their aircraft, a low-wing cantilever monoplane. It was built of wood and metal with plywood skinning, seated two and had an unfaired conventional undercarriage. Reportedly similar to the Miles Hawk, it was powered by an ADC Cirrus engine. Almost no specifications are known, apart from a loaded weight of 778 kg (1715 lb). It first flew in June 1932 and was last recorded at Cuatro Vientos, Madrid in July 1936. In 1934 the Director General de Aeronáutica issued a specification for a t ...

South African Air Force
The South African Air Force (SAAF) is the air warfare branch of South African National Defence Force, with its headquarters in Pretoria. The South African Air Force was established on 1 February 1920. The Air Force saw service in World War II and the Korean War. From 1966, the SAAF was involved in providing infantry support in the low-intensity South African Border War, Border War in Angola, South-West Africa and Rhodesia. As the war progressed, the intensity of air operations increased, until in the late 1980s when the SAAF were compelled to fly fighter missions against Angolan aircraft in order to maintain tactical air superiority. On conclusion of the Border War in 1990, aircraft numbers were severely reduced due to economic pressures as well as the cessation of hostilities with neighbouring states. History First World War After a visit to observe the 1912 military manoeuvres in Europe, Brig. Gen. Christian Frederick Beyers, C.F. Beyers (who was then Commandant-General of ...

The Royal New Zealand Air Force (RNZAF; ) is the aerial warfare, aerial military service, service branch of the New Zealand Defence Force. It was formed initially in 1923 as a branch of the New Zealand Army, being known as the New Zealand Permanent Air Force, becoming an independent air force on 1 April 1937. The RNZAF fought in World War II, Malayan Emergency, Malaya, the Korean War, Vietnam War, Vietnam and the Gulf War and has undertaken United Nations peacekeeping missions.

De Havilland Gipsy III
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre (300 cubic inch) capacity engine, later versions were designed to run inverted with increased capacity and power. The Gipsy went on to become one of the most popular sport aircraft engines of the inter-war period and was the engine of choice for various other light aircraft, trainers, liaison aircraft and air taxis, British as well as foreign, until long past World War II. Apart from helping to establish the de Havilland Aircraft Company as a manufacturer of light aircraft, it also established the company as an engine manufacturer in its own right. Gipsy engines remain in service powering vintage light aircraft. Design and development Like the ADC Cirrus, the Gipsy was born as a collaboration between aircraft manufacturer Geoffrey de ...

Dowty Group
Dowty Group was a leading British manufacturer of aircraft equipment. It was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index. The firm ceased operating as an individual entity following its acquisition by TI Group in 1992. The company has its origins as the ''Aircraft Components Company'' in 1931 and the work of British inventor and businessman George Dowty. In 1934, Dowty achieved its breakthrough sale of its innovative undercarriage designs, being contracted by the Gloster Aircraft Company to provide oleo struts for the Gloster Gauntlet biplane. In 1935, as the business expanded to meet demand, Dowty founded a new manufacturing venture to produce his aviation products, which was named ''Dowty Aviation''. It quickly secured numerous additional orders and manufacturing facilities to cope with the pressing demands of the Second World War, a significant majority of British aircraft production incorporating the firm's various products.

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. 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 Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.
