R&D history

V-22 Osprey tilt-rotor aircraft is a tilt-rotor aircraft jointly designed and manufactured by Bell Company and Boeing Company, and it is also a medium-sized transport aircraft. Tilting rotorcraft has the advantages of vertical lifting ability of helicopter and high speed, long distance and low fuel consumption of fixed-wing spiral award aircraft.

The design of V-22 is based on Bell's experimental machine XV- 15, which was developed in 1980s. In 2006, the V-22 began to serve in the US Marine Corps, replacing the CH-46 maritime knight transport helicopter for transportation and combat missions. In 2009, the US Air Force also began to equip the V-22.

operating characteristic

The V-22 has a steerable rotor propulsion device at both ends of the wing. Each device includes a rolls royce T406 turboshaft engine and a rotor with three blades. The whole propulsion device can rotate from top to front around the wing axis and can be fixed in the direction of the ticket. So that upward lift or forward thrust can be generated, and this conversion process can generally be completed in more than ten seconds.
