XV-1 Convertiplane Photos

 XV-1-01XV-1-03 The McDonnell XV-1(XH-35) was an experimental compound helicopter, developed for a joint research program with the United States Air Force and the United States Army. It was designated a "convertiplane" and explored technologies to develop an aircraft that could take off and land like a helicopter but fly at faster airspeeds, similar to a conventional airplane. The XV-1 would reach a speed of 200 mph (322 km/h), faster than any previous rotorcraft, but the program was terminated due to the complexity of the technology which gave only a modest gain in performance.
