Transcript of MV-22 Osprey
authorized funding for the development of the JVX (Joint-service Vertical Take-off/Landing Experimental) Program There were many competitors Including bell helicopter, which had been working on a prototype tiltrotor aircraft, the xv-15, since 1977 The xv-15 solved the issues inherent to past tiltrotor aircraft design. Previously, engineers had struggled with the problem of delivering the large amounts of power necessary to tilt the rotor of the aircraft from helicopter mode to "fixed-wing" mode. The xv-15 resolved this problem by taking the engines from the fuselage to the tip of the wing, in an engine/rotor,tilt-mechanism assembly called a "nacelle". But there is more to it than that... The United States had the need for a new type of aircraft... With the maneuverability of a helicopter... The troop carrying capacity of the aging CH-46... and the rapid deployment capabilities of a conventional propeller-driven aircraft. but the xv-15 was too small to meet the requirements of the project So bell partnered with boeing in 1983, Bell-boeing presented the only design, and were later awarded the design contract by the Department of the navy in 1986 By 1988, the army and airforce had backed out of the JVx program, now renamed the xv-22 program, leaving the navy and marine corps the only branches involved in the project that same year, dick cheney, the secretary of defense, pushed for the cancellation of the project dedicated development of the xv-22 began shortly after Bell-boeing received funding. the two companies evenly divided the work, including upscaling the design and modifying the structure to collapse for storage at sea but the congress decided to continue funding the program FLight testing was conducted from 1989 to 2005. During this period, it faced cancellation due to a number of crashes. two prototypes crashed during testing in New castle, deleware. and 19 marines were lost in two additional crashes in 2000 Upon completion of testing, the xv-22 was redesignated the mv-22. It entered service with the marine corps in 2007, at an average cost of 110 Million dollars per aircraft the final design:
can carry up to 24 combat troops
