Cyril Uwins
Cyril Frank Uwins OBE, AFC, FRAeS (1896–1972) was a British test pilot who worked for Bristol Aeroplane Company, where he made the first flight of 58 types of aircraft. On 16 September 1932 he broke the world aeroplane height record by climbing to (nearly miles). He eventually became the Deputy Chairman of Bristol Aircraft. He was also Chairman of the Society of British Aircraft Manufacturer between 1956 and 1958, and he was awarded the Royal Aeronautical Society silver medal for aeronautics. Early life Cyril Uwins was born at 2 Carmichael Road, South Norwood, Croydon, on 2 August 1896, the eldest son of Frank Uwins, a wood broker, and his wife, Annie Henton. He was educated at the Whitgift School, Croydon, where he developed an interest in kites. Aviation career On the outbreak of the First World War, Uwins joined the Army and served with the London Irish Rifles. In November 1915 he was promoted to second lieutenant. After active service in France he transferred to the RFC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Norwood
South Norwood is a district of south-east London, England, within the London Borough of Croydon, Greater London and formerly in the historic county of Surrey. It is located 7.8 miles (12.5 km) south-east of Charing Cross, north of Woodside and Addiscombe, east of Selhurst and Thornton Heath, south of Crystal Palace/ Upper Norwood and Anerley, and west of Elmers End and Penge. Together with Norwood New Town, it forms the electoral ward of South Norwood in the local authority of Croydon. The ward as a whole had a resident population in 2001 of just over 14,000. The south-eastern side of the district is dominated by the country park which opened in 1989. At the northern end of the town is South Norwood Lake, which was created after the reservoir for the unsuccessful Croydon Canal went out of use. It is used by the Croydon Sailing Club and local anglers who fish for carp, bream and perch. There are two secondary schools in the area along with a public leisure ce ...

Filton
Filton is a town and civil parish in South Gloucestershire, England, north of Bristol. Along with nearby Patchway and Bradley Stoke, Filton forms part of the Bristol urban area and has become an overflow settlement for the city. Filton Church dates back to the 12th century and is designated a Grade II listed building. The name of the town comes from the Old English language, Old English ''feleþe'' (hay), and ''tūn'' (farm, field). The name dates back to at least 1187. Filton has large areas of open space which include several playing fields, a golf course and the former Filton Airport (closed in 2012). Connections, districts and facilities Filton can be reached from Junction 1 of the M32 motorway, or from Junction 16 of the M5 motorway. The town is well served by rail with Filton Abbey Wood railway station, Filton Abbey Wood serving areas in the south of the town, Bristol Parkway railway station, Bristol Parkway serving areas to the north and east and Patchway railway statio ...

Bristol Pegasus
The Bristol Pegasus is a British nine-cylinder, single-row, air-cooled radial aero engine. Designed by Roy Fedden of the Bristol Aeroplane Company, it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Mercury and Jupiter engines, later variants could produce 1,000 horsepower (750 kW) from its capacity of 1,750 cubic inches (28 L) by use of a geared supercharger. Further developments of the Pegasus created the fuel-injected Bristol Draco and the diesel cycle Bristol Phoenix, both types being produced in limited numbers. In contrast, by the end of production over 30,000 Pegasus engines had been built. Aircraft applications ranged from single-engine biplanes to the four-engined Short Sandringham and Sunderland flying boats. Several altitude and distance records were set by aircraft using the Pegasus. The Bristol Siddeley company reused the name many years later for the turbofan engine used in the Hawker Siddeley Harrier a ...

Vickers Vespa
The Vickers Vespa was a British army cooperation biplane designed and built by Vickers Limited in the 1920s. While not adopted by Britain's Royal Air Force, small numbers were bought by the Irish Free State and Bolivia, the latter of which used the type during the Chaco War. One modified Vespa was used to set a world altitude record of 43,976 ft (13,407 m) in September 1932. Design and development The Vespa was designed by Vickers as a private venture to meet the requirements of Air Ministry Specification 30/24, the first prototype, the Vespa I being flown in September 1925.Mason 1994, p.173. The Vespa, which was a single-engine biplane with a slim fuselage suspended between closely spaced and highly staggered two-bay wooden wings, was delivered for evaluation by the Royal Air Force, but crash landed owing to engine trouble on 24 June 1926 and was badly damaged.Andrews and Morgan 1988, p.200. It was then rebuilt with steel, fabric-covered wings as the Vespa II, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bristol Bagshot
The Bristol Bagshot, also known as the Type 95, was a prototype heavily armed British fighter built by the Bristol Aeroplane Company and first flown in 1927. Flight testing revealed serious problems, and the project was abandoned. Development The Bagshot was built to Air Ministry Specification F.4/24 in December 1924. This called for a large twin-engined fighter aircraft with a crew of three (pilot and two gunners), a maximum speed of and a landing speed of .Mason 1992, p. 191. Initially the details of the required armament were not specified. Frank Barnwell's design to meet this requirement, the Bagshot, was a high-wing all-metal monoplane with an unusual triangular-section fabric-covered steel-tube fuselage with two upper longerons and a single lower member. The pilot sat in line with the wing's leading edge, with one gun position in the nose and another just behind the wing. The two-spar wing had a steel primary structure and duralumin nose ribs and end-members, and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroelasticity
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow; and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight and withstand large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the angle of attack of a wing which further increases the force; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases, reverses the control effectiveness; and # flutter which is the uncontained vibration that can lead ...

Control Reversal
Control reversal is an adverse effect on the controllability of aircraft. The flight controls reverse themselves in a way that is not intuitive, so pilots may not be aware of the situation and therefore provide the wrong inputs; in order to roll to the left, for instance, they have to push the control stick to the right, the opposite of the normal direction. Causes There are several causes for this problem: pilot error, effects of high-speed flight, incorrectly connected controls, and various coupling forces on the aircraft. Equipment malfunction Equipment failure may cause flight controls to behave unexpectedly, for example the possible rudder reversal experienced onboard United Airlines Flight 585. Pilot error Pilot error is the most common cause of control reversal. In unusual attitudes it is not uncommon for the pilot to become disoriented and start feeding in incorrect control movements in order to regain level flight. This is particularly common when using helmet-mounted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lympne Light Aircraft Trials
The Lympne Light Aircraft Trials were held to encourage the development of practical light aircraft for private ownership, with a strong but not exclusive emphasis on fuel economy. They were held in 1923, 1924 and 1926. Each year saw different restrictions on engine size, framed initially in terms of capacity and then weight. The ''Daily Mail'' newspaper provided cash prizes throughout though the initiating donation came from the Duke of Sutherland. The Air Ministry were prize givers in the 1924 event. The trials were held at Lympne in Kent, England. The background The Lympne events had their origin in the post-World War I state of aviation in Britain and in Germany. Military aircraft production stopped immediately after the war ended. In Britain there were large stocks of surplus aircraft available at low prices, making it hard for manufacturers to develop new models. Airlines were only slowly emerging, largely using converted military aeroplanes and having not found a certain eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Brownie
The Bristol Type 91 Brownie was a light sports aircraft produced in the United Kingdom by the Bristol Aeroplane Company in 1924. It was a low-wing cantilever monoplane aircraft of conventional configuration with fixed tailskid undercarriage. The pilot and passenger sat in tandem open cockpits. It won the £1,000 pound prize for second place at the Lympne light aircraft trials in October 1924. Design Bristol had not built an aircraft to compete in the 1923 Lympne light aircraft trials, which had been for aircraft with engines of 750 cc or less, making use of Bristol's Cherub engine impossible. The rules were changed for the 1924 trials, permitting engines of up to 1,100 cc to be used, and accordingly Frank Barnwell started design work on a competitor early in 1924. He produced studies for alternative wood and metal aircraft, and after consideration of these the Board of Bristol Aircraft authorised the production of two aircraft on 4 February, adding a third on 5 May. All three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Tourer
The Bristol Tourer was a British civil utility biplane produced in the years following the First World War, using as much as possible from the design of the Bristol Fighter aircraft. Bristol Tourers were delivered with a variety of engines, subject to availability and customer desires; these included the Rolls-Royce Falcon, Siddeley Puma, Hispano-Suiza 8, and Wolseley Viper. Many Tourers were fitted with a canopy to cover the one or two passenger seats in the rear cockpit, giving the type its original name of Coupé. The pilot's cockpit, however, remained open. Bristol Tourers operated by Western Australian Airways made the first scheduled airline services in Australia, commencing on 4 December 1921 between Perth and Geraldton. Variants ;Type 27 :First Tourers for the British Controller of Civil Aviation, fitted with Rolls-Royce Falcon engines and dual controls (3 built) ;Type 28 :Similar to Type 27 with canopy for rear seat ;Type 29 :Siddeley Puma-engined version for Bri ...

Bristol Scout F
The Bristol Scout E and F were a British single-seat biplane fighters built in 1916 to use newer and more powerful engines. It was initially powered by the Sunbeam Arab, but the third prototype was used as a testbed for the Cosmos Mercury, marking the start of Roy Fedden's association with the Bristol Aeroplane Company. The Armistice ended hopes of production. Development By the end of 1916 there was a shortage of suitably powerful engines for single-seat fighters needed for air superiority. One of the few available was the Hispano-Suiza 8, but it was unreliable and production was being absorbed by the need to power the Royal Aircraft Factory S.E.5A that was entering service. Frank Barnwell of the Bristol Aeroplane Company designed a single-seat biplane, called the Scout E, around a proposed ten-cylinder water-cooled radial engine designed by Harry Ricardo and Frank Halford, but this failed to materialise and another powerplant was sought. The Company gained an Air Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
