The Bell XV-15 Tilt Rotor was an aircraft that could takeoff, land, and hover like a helicopter, but with the speed of an airplane. The proprotor engines tilt from vertical to horizontal to allow the XV-15 to operate at speeds of 550 kph (345 mph). The success of the XV-15 lead to the development of the MV-22 Osprey as a replacement for Marine transport helicopters.
