The Curtiss-Bleecker Helicopter was an American prototype rotary wing aircraft, introduced in 1926. The thrust of the aircraft was distributed from a central mounted engine through shafts to propellers mounted on each rotor blade. ==Design and development== The Bleecker Helicopter was designed by Maitland B. Bleecker, a junior engineer from the National Advisory Committee for Aeronautics. The aircraft was constructed by Curtiss Wright for $250,000 over the course of four years at Garden City.〔("New Plane May Fly Straight Up in Air." ) ''Popular Science Monthly'', September 1930, pp. 20-21.〕 The aircraft featured a rotary wing design with a single engine. Each rotor, painted silver and yellow, had an individual propeller for thrust and a trailing control surface called a "stabovator" to change pitch of the rotor. The aircraft was controlled by a stick that operated like a modern helicopter collective control. Yaw was controlled with a "Spin Vane" that used downwash from the rotor to pivot the aircraft with foot pedals.〔
