The V-22 Osprey is a joint service, multimission, military tiltrotor aircraft with both a vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capability. It is designed to perform missions like a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
The V-22 was developed by Bell Helicopter Textron, which manufactures it in partnership with Boeing Helicopters. The initial operators are the U.S. Marine Corps and United States Air Force. The FAA classifies the Osprey as a model of powered lift aircraft.
The Osprey is the world's first production tiltrotor aircraft, with one three-bladed proprotor, turboprop engine, and transmission nacelle mounted on each wingtip. For takeoff and landing, it typically operates as a helicopter with the nacelles vertical (rotors horizontal). Once airborne, the nacelles rotate forward 90° in as little as 12 seconds for horizontal flight, converting the V-22 to a more fuel-efficient, higher-speed turboprop airplane.
STOL rolling-takeoff and landing capability is achieved by having the nacelles tilted forward up to 45°. For compact storage and transport, the V-22's wing rotates to align, front-to-back, with the fuselage. The proprotors can also fold in a sequence taking 90 seconds.
