Design and development
In March 1960 the Curtiss-Wright Corporation developed the X-100, a prototype for a new, vertical takeoff 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 for 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 two 13 ft (4.0 m) propellers 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.
