A tiltrotor is an aircraft which utilizes a pair or more of powered rotors (sometimes called proprotors) mounted on rotating shafts or nacelles at the end of a fixed wing for lift and propulsion, and combines the vertical lift capability of a helicopter with the speed and range of a conventional fixed-wing aircraft. Models include the V-22, XV-15 and Bell 609
Tiltrotors are the future of military and civilian flight.
