McDonnell XV-1

The McDonnell XV -1 was an autogyro, the possessed to start a switchable drive the main rotor blade tip.

History

The experimental aircraft was developed in the 1950s by Kurt Friedrich von Hohenems and Doblhoff at the McDonnell Aircraft Corporation to investigate technically possible speeds for rotor flight. The speed of classical helicopters in level flight is limited by the one-sided loss of lift, as the blades move back in the rotation. Propulsion was by a normal piston engine ( a radial engine R -975 from Continental Motors ) worried that powered a mounted behind the hull propeller. To start the engine power was, however, coupled to two compressors. The empennage was supported by two booms. For the first time flew the XV -1 on February 11, 1954 without restraint. On October 10, 1955, exceeded (320 km / h) for the first time in an autogyro 200 mph. Two aircraft were built before the program was discontinued in 1957.
