Paul Cornu
Paul Cornu (June 15, 1881 – 6 June 1944) was a French engineer. ==Career== French engineer Paul Cornu made history by designing the world's first successful manned rotary wing aircraft. Cornu first built an unmanned experimental design powere by a 2 hp Buchet engine. It was powered by a Antoinette engine.〔(eurocopter.com )〕 He piloted this construction himself at Normandy, France on November 13, 1907. Previously, a French helicopter, the Breguet-Richet Gyroplane I, had managed to lift off under its own power, but it had been held in position by men standing on the ground. Cornu's performance was a considerable progress because his aircraft flew without additional support and lifted Cornu about 30 cm (1 ft) for 20 seconds . Unfortunately this early helicopter was scarcely maneuverable and had only a few additional flights. The construction was not much further developed by this technical pioneer, who had to keep on making a living by manufacturing bicycles.
