The Curtiss-Wright X-19 was an experimental American VTOL - changing aircraft .
development
In March 1960, the Curtiss-Wright Corporation developed the prototype for a new type of vertical take-off transport aircraft called the X-100 . The X-100 had a single engine that powered two tilt rotors on the wing tips; at the stern there were movable exhaust nozzles for controlling slow flight.
Curtiss-Wright developed the much larger X-200 from the X-100, of which the US Air Force ordered two copies as the X-19A .
The X-19 was a shoulder -wing aircraft with two wings attached one behind the other with a wingspan of 5.94 m (front) and 6.55 m (rear). At their tips there were a total of 4 propellers with a diameter of almost 4 m. These and the gondola could be turned upwards by 90 degrees so that the aircraft could take off and land like a helicopter. The propellers were driven by two Avco- Lycoming T55-L-5 shaft engines with 1640 kW (2230 hp) each, housed in the fuselage .
The first flight of the X-19 took place in November 1963 (according to other sources on June 26, 1964). The top speed was 730 km / h, the payload was around 500 kg.
Originally, the X-19 was to be further developed into a vertical take-off transport aircraft. However, after the crash of the first prototype on August 25, 1965, the program was discontinued. The second example (S / N 62-12198A) has been in the possession of the National Museum of the United States Air Force in Dayton, Ohio since 2007 and is due for restoration.
It was not until the Bell Boeing V-22 Osprey that a comparable aircraft went into series production, but it is significantly larger than the X-19 and only has two propellers that can be swiveled together with the engines.
