XV-15

Bell 301



In 1972, with funding from NASA and the US Army, Bell Helicopter Textron started development of the XV-15, a twin-engine tiltrotor research aircraft.

The first flight was on May 3rd, 1977. Two aircraft were built to prove the tilt-rotor design and explore the operational flight envelope for military and civil applications.

The first prototype, N702NA, crash in 1992 but the second, N703NA, continue to perform test flights until 2003 when was donated to the Smithsonian museum. All the experience gained with this aircraft lead to the BA609 and V-22 Osprey programs .
