Howard Wright 1909 Biplane
The Howard Wright 1909 Biplane was an early British experimental aircraft designed and built by Howard T Wright. It was displayed at the first Aero Show at Olympia in March 1909, and although only one was built, it was the first of a series of aircraft built by Wright that were to earn him brief fame as one of England's foremost aircraft manufacturers in the early years of flight.
==Development and design==
Howard Wright was an engineer who had previously worked with Hiram Maxim and built a number of experimental helicopters designed by Federico Capone. In December 1908 he was asked to build an aircraft by Malcolm Serr Keaton. Wright's design was of similar layout to the contemporary Voisin aircraft, being a pusher biplane with a front-mounted elevator and a rear-mounted box-like biplane tail with elongated fixed end-surfaces and a single central rudder.
Wright's aircraft differed in some details from Voisin's designs, most obviously in having biplane front elevators and an undercarriage consisting of a single wheel carried by a pyramid of struts in front of the wings, with supplementary wheels on either wingtip and a tailwheel. This arrangement resembled that of the REP monoplane which had been displayed along with examples of Voisin aircraft at the Paris Aero Salon that December, and was intended to provide a degree of experience in lateral control of the aircraft without actually lifting off.
The fuselage was a tapered box-girder fabricated from welded steel tubes, the pilot's seat being under the wings leading edge with the engine behind him. This was a 50 hp Metallurgique which drove the aircraft's most novel feature, a pair of contra-rotating two bladed propellers driven by a patented 3:1 reduction gearbox. The wings had ash spars and spruce ribs, with Voisin-style "side-curtains" between the ends of the wings. Lateral control was by means of four small ailerons fitted to the trailing edges of both wings, a feature not found on Voisin's aircraft. The fabric-covered wood tail assembly was carried on steel booms. Steel tube was also used for the interplane struts, these being of a special streamlined section.〔(Howard Wright )''Flight'' 27 March 1909〕
