Vickers R.E.P. Type Monoplane
The Vickers R.E.P. Type Monoplanes were a series of single-engined monoplane aircraft built by Vickers prior to the outbreak of the First World War. They were developed from a French design for which Vickers had purchased a license, with eight being built.
Design and development
On 1 January 1911 Vickers, Sons and Maxim, entered into a license agreement to build aircraft and aero-engines designed by the Frenchman Robert Esnault-Pelterie, and sell them in Britain and its Empire. Following the agreement, Vickers purchased a French-built R.E.P. monoplane for use as a demonstrator together with an R.E.P.-built rear fuselage.The design was redrawn from metric to imperial measurements by Vickers, while the first example was built at the Vickers factory at Erith, Kent, using the French-built rear fuselage and a French-built engine, but was otherwise the rest of the components were Vickers-built. It made its maiden flight from Vickers' new airfield at Joyce Green, near Dartford in July 1911, piloted by Captain Herbert F. Wood, the manager of Vickers' aviation department.
The aircraft was a shoulder-winged monoplane, with a deep but narrow fuselage of fabric-covered steel-tube construction, accommodating two people in tandem. A single five-cylinder air-cooled R.E.P. "fan" engine rated at driving a two-bladed propeller was fitted in the aircraft's nose, while the aircraft had a conventional landing gear, with both wheels and skids. The wings were of wood and steel construction, with lateral control by wing-warping, with the pilot operating a joystick.
The first five monoplanes were basically similar, and were powered by R.E.P engines, with the fifth one having a deeper fuselage. The sixth aircraft, built for the 1912 British Military Aeroplane Competition was noticeably different, with side-by-side seating for its two crew, a shorter wingspan, while a Viale radial engine was fitted.
The seventh aircraft reverted to the tandem layout and longer wingspan of the first five aircraft, but replaced the R.E.P. engine with a Gnome rotary engine, while the eighth, and final example, was similar to the sixth aircraft, with a 70–80 hp Gnome rotary.
