The V-22 Osprey is a joint-service, medium-lift, multimission tilt-rotor aircraft developed by Boeing and Bell Helicopters.
A total of 112 V-22s are currently operated by the US Air Force (USAF) and the US Marine Corps (USMC).
The aircraft operates as a helicopter when taking off and landing vertically. The nacelles rotate 90° forward once airborne, converting the aircraft into a turboprop aircraft.
The aircraft can provide VTOL (vertical take-off and landing) with a payload of 24 troops, or 6,000lb of cargo at 430nm combat range, or VTOL with a payload of 8,300lb of cargo for a range of 220nm.
The helicopter is self-deployable worldwide, with a ferry range over 2,100nm. Normal operating range is up to 1,100nm.
The tilt-rotor aircraft is available in three configurations: the Combat Assault and Assault Support MV-22 for the USMC and the US Army; the long-range special operations CV-22 for US Special Operations Command (US SOCOM); and the US Navy HV-22, for combat search and rescue, special warfare and fleet logistic support.
V22 dual tilt rotor design
The V-22 is fully shipboard compatible, with the world’s first complete blade fold and wing stowage system. It is able to operate off all US Navy L-class amphibious ships, the LHA/LHD assault carriers, and can be stowed on full-size CV/CVN carriers.
For stowage, the wings are rotated to lie above and parallel to the fuselage to create a compact rectangular volume.
The automatic wing and rotor folding sequence, which can be completed in 90 seconds in a 60kt wind, is as follows: the aircraft lands in helicopter mode; the two outboard blades of each rotor are folded inboard; the nacelles are rotated forward to cruise mode; and the wings are rotated by 90° clockwise.
