Design and developmentEdit
In March 1960 the Curtiss-Wright Corporation developed the X-100, a prototype for a new, vertical take-off transport aircraft. The X-100 had a single turboshaft engine, which propelled two tilting-rotors, while at the tail swivelling nozzles used the engine's exhaust gases to give additional control in hovering or slow flight.
From the X-100 Curtiss-Wright developed the larger X-200, of which the United States Air Force ordered two prototypes designated the X-19A.
The X-19 had high-mounted tandem wings. Each wing mounted a 13 ft (4.0 m) propeller that could be rotated through 90 degrees allowing the aircraft to take off and land like a helicopter. The propellers were driven by twin Avco Lycoming T55-L-5 turboshaft engines mounted in the fuselage.
The first flight of the X-19 took place in November 1963 (other sources give 26 June 1964). It was intended that the X-19 would be developed into a VTOL transport aircraft. However the first X-19 was destroyed in a crash on 25 August 1965, and the program was subsequently cancelled. The second prototype is currently being stored in the restoration facilities at the National Museum of the United States Air Force in Dayton, Ohio.
