Design and development

The first Gordon England design, the G.E.1, was a two-bay equal-span tractor configuration biplane powered by a Clerget four-cylinder water-cooled engine, driving the two-bladed propeller via a

s 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. 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. The tailplane was enlarged and mounted in a mid-fuselage position. Two examples were built, one powered by a 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 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 .Bruce 1982, pp. 13–14, 200. Bristol did have some success, however: their monoplane design being placed equal third. The design was further refined in the G.E.3, of which two were built for the

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.Barnes 1988, p. 68.
