The Bell XV-15 is an American tiltrotor VTOL aircraft. It was the second successful experimental tiltrotor aircraft and the first to demonstrate the concept's high speed performance relative to conventional helicopters.

Sep 11, 2003 · The unique XV-15 Tiltrotor aircraft is seen in vertical flight at NASA’s Dryden (now Armstrong) Flight Research Center. The XV-15s, manufactured by Bell, were involved in limited research at Dryden in 1980 and 1981.

The XV-15 was Bell's second successful experimental tiltrotor aircraft after the XV-3. Powered by two 1550 shps Textron Lycoming LTC1K-4K turboshaft / turboprop engines derivated of the T53-L-13B.

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.

Aug 21, 2015 · The Bell XV-15 tiltrotor demonstrator was the much-flown progenitor of today’s Bell-Boeing V-22 Osprey. The XV-15 could take off and land in confined spaces like a helicopter, but fly horizontally with the speed of a fixed-wing airplane. The VTOL aircraft first flew on …

The United States Bell XV-15 was the second successful experimental Tiltrotor VTOL aircraft and the first to demonstrate the concept’s high speed performance relative to conventional helicopters. Role: Experimental VTOL aircraft; Manufacturer: Bell Helicopter Textron; First flight: May 3, 1977; Status: Active service; Number built: 2

The two Bell XV-15 Tiltrotor aircraft were involved in limited research at the Hugh L. Dryden Flight Research Center in 1980 and 1981. The XV-15 combines standard aircraft cruise flight with vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities.
