The Grahame-White Type XI (also known as the "Naval and Military Biplane") was an early aircraft built in the United Kingdom and marketed as being particularly well-suited to military applications. An aerospace manufacturer is a company or individual involved in the various aspects of designing building testing selling and maintaining Aircraft, Aircraft parts The Grahame-White Aviation Company was an early British aircraft manufacturer and flying school established by Claude Grahame-White at Hendon in 1911 It was a two-bay biplane of pod-and-boom configuration with unstaggered wings of slightly unequal span. The pilot and an observer sat in tandem, open cockpits in a streamlined nacelle, with the engine mounted pusher-fashion behind them. Unusually for an aircraft of this period, the propeller was not driven directly by the engine, but rather, via a sprocket and chain system that geared it down in the ratio of 14/23. The undercarriage was of the fixed, tailskid type but was designed to be easily exchanged for pontoons. Construction throughout was fabric-covered wood, with the exception of a neat aluminium cowling for the engine and transmission. A sample was exhibited at the Olympia Aero Show in 1914. Olympia is an exhibition centre in West Kensington, London, W14, England.
