Fred Landgraf formed the Landgraf Helicopter Company in September 1943 to develop and manufacture the H-2. It had an enclosed structure for one pilot and an 85 hp (63 kW) radial engine driving two rotors, each rotor fitted to a short boom on each side of the fuselage. It had a fixed tricycle landing gear. The H-2 first flew on 2 November 1944 and the company was awarded a development contract by the United States Army. It was not developed or bought and the company ceased operations by the end of the 1940s. |
