Doak VZ-4DA V-STOL (1958)
About the Design
Conceived in 1956 and first test flown in 1958, the Doak VZ-4DA was the first experimental VTOL to employ the tilt-duct-fan concept (Wing tip-mounted fans were positioned vertically for take-off and landing, then turned horizontally for conventional flight). Because of budget constraints, the VZ-4DA used many parts cannibalized from other aircraft, including the landing gear of a Cessna 1982, the seats of an F-51, and the duct actuators from a T-33. Powered by a Lycoming T-53-L-1 turboshaft engine, the VZ-4DA had a top speed of 370 mph.
In the late 1950s the Doak VZ-4DA VTOL was transferred to the control of NASA, which continued experiments until 1972. It was then retired to the US Amy Transportation Museum in Ft. Eustis, Va.
