Pasted from Wikipedia: Bell-Boeing V-22 Osprey
The Bell-Boeing V-22 Osprey is a multi-mission, military, tiltrotor aircraft with both a vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capability. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
The V-22 originated from the U.S. Department of Defense Joint-service Vertical take-off/landing Experimental (JVX) aircraft program started in 1981. It was developed jointly by the Bell Helicopter, and Boeing Helicopters team, known as Bell Boeing, which produce the aircraft.[4] The V-22 first flew in 1989, and began years of flight testing and design alterations.
The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007. The Osprey’s other operator, the U.S. Air Force fielded their version of the tiltrotor in 2009. Since entering service with the U.S. Marine Corps and Air Force, the Osprey has been deployed for combat operations in Iraq and Afghanistan.

Development
Early development
The failure of the Iran hostage rescue mission in 1980 demonstrated to the United States military a need[5] for "a new type of aircraft, that could not only take off and land vertically but also could carry combat troops, and do so at speed."[6] The U.S. Department of Defense began the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program in 1981, under U.S. Army leadership. Later the U.S. Navy/Marine Corps took the lead.[7][8] The JVX combined requirements from the Marine Corps, Air Force, Army and Navy.[9][10] A request for proposals (RFP) was issued in December 1982 for JVX preliminary design work. Interest in the program was expressed by Arospatiale, Bell Helicopter, Boeing Vertol, Grumman, Lockheed, and Westland. The DoD pushed for contractors to form teams. Bell partnered with Boeing Vertol. The Bell Boeing team submitted a proposal for a enlarged version of the Bell XV-15 prototype on 17 February 1983. This was the only proposal received and a preliminary design contract was awarded on 26 April 1983.[11][12]
The JVX aircraft was designated V-22 Osprey on 15 January 1985; by March that same year the first six prototypes were being produced, and Boeing Vertol was expanded to deal with the project workload.[13][14] Work has been split evenly between Bell and Boeing. Bell Helicopter manufactures and integrates the wing, nacelles, rotors, drive system, tail surfaces, and aft ramp, as well as integrates the Rolls-Royce engines and performs final assembly. Boeing Helicopters manufactures and integrates the fuselage, cockpit, avionics, and flight controls.
| Why people choose sea cruises? And why once having visited cruise, it would be desirable to come back there again and again? From year to year, the ships in swimming from century to century leave, and always strangers wave to leaving liners, say goodbye to them. And proud handsome men salute to them in the answer, as though telling «thanks for a shelter and good-bye!». |
