Sopwith Snapper
The Sopwith Snapper was a prototype British fighter aircraft of the First World War. A single-engined biplane designed by the Sopwith Aviation Company to replace the Sopwith Snipe fighter, it first flew after the end of the war, but did not enter service owing to the failure of its engine, only three aircraft being built. Development and design In 1918, the British Air Ministry developed a requirement for a single-seat fighter to replace the Royal Air Force's Sopwith Snipes, even though the Snipe had yet to enter service. This requirement, RAF Type 1, specified the new ABC Dragonfly air-cooled radial engine, which had been ordered into production in large numbers on the basis of excellent promised performance and ease of production despite the fact that it had yet to complete testing. To meet this requirement, Sopwith produced two new and completely different designs, a triplane (the Sopwith Snark) and a more conventional biplane, which was named the Snapper. The Air Minist ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Westland Wagtail
The Westland Wagtail was a prototype British fighter aircraft of the First World War. A single-engined tractor biplane, the Wagtail was a failure owing to the unreliability of its engine, only five being built. Development and design The Westland Wagtail was designed by Westland Aircraft of Yeovil in 1917 to meet the Royal Air Force Specification IA for a light fighter with superior performance to the Sopwith Camel. Westland's design team, led by Robert Bruce, the Company's manager and Arthur Davenport, Chief Draughtsman, came up with a design for a small single bay biplane, powered (like the other competitors for the Specification, the BAT Bantam and the Sopwith Snail) by the 170 hp (127 kW) ABC Wasp radial engine. The Wagtail was of conventional wood and fabric construction, with the upper wing centre-section having a large cut-out to improve the pilot's view, and carrying an armament of two Vickers machine guns mounted over the nose.Bruce 1969, pp.132–133.Mason ...

Nieuport Nighthawk
The Nieuport Nighthawk was a British fighter aircraft developed by the Nieuport & General Aircraft company for the Royal Air Force towards the end of the First World War. Although ordered into production before the aircraft first flew, it did not enter large scale service with the RAF owing to unreliable engines. Re-engined aircraft did see service in Greece, serving from 1923 to 1938. Design and development The Nieuport & General Aircraft Co. Ltd. was formed on 16 November 1916 to produce French Nieuport aircraft under licence.Bruce August 1963, p. 248. During 1917, hiring Henry Folland as chief designer, the company started to design its own aircraft, with the first type, the Nieuport B.N.1 fighter (the designation signifying British Nieuport) flying early in 1918. To produce a fighter to replace the Sopwith Snipe in service with the RAF, the Air Ministry produced RAF Specification Type 1 for a single-seat fighter to be powered by the ABC Dragonfly engine. This was a radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BAT Basilisk
The BAT F.K.25 Basilisk was a prototype British fighter aircraft of the First World War. A single engined biplane intended to meet a requirement to replace the Sopwith Snipe, the Basilisk was unsuccessful, only three being built. Development and design In 1918, the British Air Ministry issued the RAF Type 1 specification for a single-seat fighter, powered by the new (and untried) ABC Dragonfly air cooled radial engine to replace the Sopwith Snipe. To meet this requirement, Frederick Koolhoven, (formerly of Armstrong Whitworth Aircraft and before that Deperdussin) chief designer of the British Aerial Transport Company of London, designed the F.K. 25 Basilisk.Lewis 1979, pp.128, 130. Like Koolhovens earlier F.K.23 Bantam, the Basilisk was a two-bay biplane with a wooden monocoque fuselage, but was larger and heavier to accommodate the larger engine and the equipment required by the Specification. Armament was two Vickers machine guns mounted ahead of the pilot, and enclosed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong Whitworth Ara
The Armstrong Whitworth Ara was an unsuccessful British single-seat biplane fighter aircraft of the First World War built by Armstrong Whitworth. Design and development In early 1918, the British Air Ministry wrote RAF Specification Type 1 for a single-seat fighter to replace the Sopwith Snipe. The specified engine was the ABC Dragonfly, a new radial engine which had been ordered into production based on promised performance before any testing had been carried out. To meet this specification, Armstrong Whitworth's chief designer, Fred Murphy, produced the Armstrong Whitworth Ara, three prototypes being ordered.Bruce 1965, p.20. The Ara was a two-bay biplane. It had a square fuselage, the engine was covered in a pointed cowling, but with the cylinder heads exposed. The upper wing was low to give the pilot a better upwards view.Taylor 1990, p.48. As with the other fighters built to meet the Type 1 specification, the Dragonfly engine proved to be the Ara's undoing, demonstrating ...

303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns a ...

Radial Piston Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added in ...

Royal Aircraft Establishment
The Royal Aircraft Establishment (RAE) was a British research establishment, known by several different names during its history, that eventually came under the aegis of the Ministry of Defence (United Kingdom), UK Ministry of Defence (MoD), before finally losing its identity in mergers with other institutions. The first site was at Farnborough Airfield ("RAE Farnborough") in Hampshire to which was added a second site RAE Bedford (Bedfordshire) in 1946. In 1988 it was renamed the Royal Aerospace Establishment (RAE) before merging with other research entities to become part of the new Defence Research Agency in 1991. History In 1904–1906 the Army Balloon Factory, which was part of the Army School of Ballooning, under the command of Colonel James Templer (balloon aviator), James Templer, relocated from Aldershot to the edge of Farnborough Common in order to have enough space to inflate the new "dirigible balloon" or airship which was then under construction.Walker, P; Early Avi ...

Harry Hawker
Harry George Hawker, MBE, AFC (22 January 1889 – 12 July 1921) was an Australian aviation pioneer. He was the chief test pilot for Sopwith and was also involved in the design of many of their aircraft. After the First World War, he co-founded Hawker Aircraft, the firm that would later be responsible for a long series of successful military aircraft. He died on 12 July 1921 when the aircraft he was to fly in the Aerial Derby crashed in a park at Burnt Oak, Edgware, not far from Hendon Aerodrome. Early life Hawker was born on 22 January 1889 at Moorabbin, Victoria in Australia, the second son of George Hawker, a blacksmith, and Mary Ann Gilliard Anderson.''The Automobile'' September 2007 Harry Hawker - Automobilist. author Bruce Lindsay He attended Moorabbin Primary School.

Aerial Derby
The Aerial Derby was an air race in the United Kingdom sponsored by the '' Daily Mail'' in which the competitors flew a circuit around London. It was first held in 1912, with subsequent races in 1913 and 1914. Suspended during the First World War, the event was revived in 1919 with a "Victory Aerial Derby". Further races were held in 1920, 1921,1922 and 1923. Although a race was scheduled for 1924 there were insufficient entries, and the event was cancelled and not held again. 1912 The first race, held on Saturday 8 June consisted of a single circuit of an course, starting and finishing at Hendon Aerodrome with control points at Kempton Park, Esher, Purley and Purfleet. At these contestants had to fly low enough for the judges to see the race number of their aircraft. The first prize was £250 and a gold cup. The first competition was the subject of enormous public interest, with around 45,000 people paying to view the start and finish at Hendon and enormous crowds gather ...

Brooklands
Brooklands was a motor racing circuit and aerodrome built near Weybridge in Surrey, England, United Kingdom. It opened in 1907 and was the world's first purpose-built 'banked' motor racing circuit as well as one of Britain's first airfields, which also became Britain's largest aircraft manufacturing centre by 1918, producing military aircraft such as the Wellington and civil airliners like the Viscount and VC-10. The circuit hosted its last race in August 1939 and today part of it forms the Brooklands Museum, a major aviation and motoring museum, as well as a venue for vintage car, motorcycle and other transport-related events. History Brooklands motor circuit The Brooklands motor circuit was the brainchild of Hugh Fortescue Locke-King, and was the first purpose-built banked motor race circuit in the world. Following the Motor Car Act 1903, Britain was subject to a blanket speed limit on public roads: at a time when nearly 50% of the world's new cars were produced in ...
