The Bristol Gordon England biplanes were a series of early British military biplane aircraft designed by Eric Gordon England for the Bristol Aeroplane Company that first flew in 1912. Designed for easy ground transport, the aircraft could be quickly disassembled.
The first Gordon England design, the G.E.1, was a two-bay equal-span tractor configuration biplane powered by a 50 hp (37 kW) Clerget four-cylinder water-cooled engine, driving the two-bladed propeller via a chain drive giving a 2:1 speed reduction. The crew of two were accommodated side-by-side in a single cockpit, fitted with dual controls. The empennage consisted of a small triangular tailplane and elevators mounted on top of the rectangular-section fuselage and elongated triangular fins above and below the fuselage with the unbalanced rudder mounted on the trailing edge.
After testing during May and June 1912 the fins were removed, and an enlarged aerodynamically balanced rudder fitted. The aircraft was sold to the Deutsche Bristol Werke. However it was found to be unsuitable for use as a trainer, and was returned to the Bristol works at Filton in September 1912 and scrapped. [1]
The G.E.2 was an enlargement and refinement of the previous design. The fuselage was carried on the innermost pairs of interplane struts, so that there was a gap between the fuselage and the lower wing, and a shallow curved fairing was added to the top and bottom of the fuselage. [2] The tailplane was enlarged and mounted in a mid-fuselage position. Two examples were built, one powered by a 100 hp (75 kW) Gnome double Omega twin-row rotary engine and the other with a 70 hp (53 kW) four-cylinder inline water-cooled Daimler. Both were entered in the British military aeroplane trials held in August 1912, the first to be flown by Gordon England and the other by Howard Pixton [3] [4] but were unsuccessful, completing only the quick-assembly tests. The Daimler-engined version proved underpowered, and the other aircraft was damaged in an accident early in the competition, which was won by the Cody V biplane . [5] Bristol did have some success, however: their monoplane design being placed equal third. [6]
The design was further refined in the G.E.3, of which two were built for the Turkish government. This had a fuselage faired to a circular cross-section with the crew in two tandem cockpits, with fuel and oil tanks sufficient for three hours flight between them, and was powered by an 80 hp (60 kW) Gnome Lambda single-row rotary engine threequarters enclosed in a circular cowling. The continuous inmost interplane struts were replaced by short struts between the lower longerons and the lower wing and a cabane consisting of two sets of inverted V struts supplemented by a single strut between the centre of the upper wing and the nose of the aircraft. Trials of the aircraft revealed that the wing spars were too flexible, and although an attempt was made to address this problem by adding short kingpost-bracing to the rear spar, by this time the Italian blockade of Turkey made delivery difficult, and no further development was carried out.

General characteristics
Performance
The Boxkite was the first aircraft produced by the British and Colonial Aeroplane Company. A pusher biplane based on the successful Farman III, it was one of the first aircraft types to be built in quantity. As the type was used by Bristol for instruction purposes at their flying schools at Larkhill and Brooklands many early British aviators learned to fly in a Boxkite. Four were purchased in 1911 by the War Office and examples were sold to Russia and Australia. It continued to be used for training purposes until after the outbreak of the First World War.
The Bristol Biplane Type 'T', sometimes called the Challenger-Dickson Biplane, was a derivative of the Bristol Boxkite. It was built in 1911 by the British and Colonial Aeroplane Company and was designed as a cross-country racing aircraft for Maurice Tabuteau.
The Vickers F.B.19 was a British single-seat fighting scout of the First World War, developed from the Barnwell Bullet prototype, and sometimes known as the Vickers Bullet. It served with the Royal Flying Corps and the Imperial Russian Air Service, which subsequently led to the Red Air Force adopting it during the Russian Civil War.
The Avro Type E, Type 500, and Type 502 made up a family of early British military aircraft, regarded by Alliott Verdon Roe as his firm's first truly successful design. It was a forerunner of the Avro 504, one of the outstanding aircraft of the First World War.
The Bristol T.B.8, or Bristol-Coanda T.B.8 was an early British biplane built by the Bristol Aeroplane Company and designed by the Romanian Henri Coandă. Fifty four Bristol T.B.8s were built, being mainly used as a trainer. A small number of Bristol T.B.8s were briefly used as bombers at the start of the World War I by the Royal Naval Air Service.
The Bristol Coanda Monoplanes were a series of monoplane trainers designed by the Romanian designer Henri Coandă for the British company British and Colonial Aeroplane Company.
The Blackburn Triplane was a single-engine pusher single-seater, designed specifically to attack Zeppelins. It flew in 1917, but was not successful.
The Hydro no.120 was a Romanian-designed two-seat, single-engine biplane configured as a single-float seaplane. Built by Bristol in 1913, it was lost on its first flight.
The Vickers Type 253 was a single-engined two-seat biplane general-purpose military machine built to a 1930 government specification. It won a production contract, but this was transferred to the same company's monoplane equivalent, the Wellesley. Only one Type 253 was built.
The Short S.41 was a British single-engined biplane built for the Royal Navy in 1912. Capable of being operated either on wheels or floats, it was successful enough for a further two similar aircraft to be built, with the type remaining in use until the early years of the First World War.
The Dunne D.8 of 1912 was a tailless swept wing biplane, designed by J. W. Dunne to have inherent stability. One example was supplied to RAE Farnborough. License-built Burgess-Dunne models were used by the US Signal Corps and United States Navy and the short-lived Canadian Aviation Corps. It was the latter's first and only warplane.
The ASL Viking was a single-engined two seater biplane aircraft designed and built by Horatio Barber's Aeronautical Syndicate Ltd. at Hendon. It was first flown in January 1912.
The Bristol Racing Biplane was a British single-seat biplane designed to combine the performance of a monoplane but using the strength of the biplane. It was designed by Robert Grandseigne and Léon Versepuy, who were supervised by George Challenger for the British & Colonial Aeroplane Company of Bristol, it crashed on its first flight.
The Bristol S.S.A.,, was an armoured scout built at Bristol in 1914 to fulfill a French government order.
The Paalson Type 1, (Pålson), was a Swedish single-seat sport aircraft built around 1920. It was of conventional single-seat biplane layout but had some unusual features such as girder type interplane struts, a novel main undercarriage axle mounting and a mechanism allowing adjustment of the angle of incidence of the upper wing.
The Spijker, Spyker V.1 or Spyker-Trompenburg V.1, was a single seat biplane fighter built in the Netherlands during World War I. It was underpowered and did not go into production.
The NVI F.K.32 was a tandem two seat biplane training aircraft designed and built in the Netherlands in the mid-1920s. It did not go into service.
The Ponnier L.1 was an early French biplane single seat scout, built just before World War I. It did not reach production.
The Bristol P.B.8, or Bristol-Coanda P.B.8', was an early British-built, Romanian-designed two-seat biplane trainer made by the Bristol Aeroplane Company in 1914. Only one was completed, which was never flown.
The Caudron Type D was a French pre-World War I single seat, twin-boom tractor biplane, a close but slightly smaller relative of the two seat Caudron Type C. More than a dozen were completed, one exported to the United Kingdom, where they may also have been licence built, and three to China.
