Cierva C.29

The Cierva C.29 was a five-seat British cabin autogyro built in 1934 as a joint venture between Westland Aircraft and Cierva.^[1] The rotor system and rotors were designed by Cierva and the fuselage by Westland. It was powered by a 600 hp (447 kW) Armstrong Siddeley Panther II engine with a two-bladed tractor propeller; the engine also drove the three-bladed rotor via a clutched shaft. The C.29 suffered from ground resonance during ground running and was not flown.^[1] It was later acquired for evaluation by the Royal Aircraft Establishment but it was unable to cure the resonance problem and the autogiro was scrapped in 1939.
