Paul Cornu (June 15, 1881 – 6 June 1944) was a French engineer.
French engineer Paul Cornu made history by designing the world's first sucessful manned rotary wing aircraft.
Cornu first built an unmanned experimental design powere by a 2 hp Buchet engine.
It was powered by a 24 horsepower (18 kW) Antoinette engine. 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.
Paul Cornu died in 1944 in Lisieux -France, when his home was destroyed during the bombardment that accompanied the Normandy landings.
