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.

2003年9月11日 · 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 Tilt Rotor technology demonstrator was the culmination of efforts begun in the early 1950s to produce an aircraft that could takeoff, land, and hover like a helicopter, but with the speed of an airplane.

Designated XV-15, the Model 301 looked like a high-wing monoplane with two wingtip-mounted 1.550shp Avco Lycoming LTC1K-4K turboshafts, each fitted with 25ft diameter three-blade propeller-rotors able to be tilted from vertical take-off configuration to …

2015年8月21日 · 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 rotor pylons tilt from vertical to horizontal to eliminate the speed barriers imposed on conventional helicopters by retreating-blade stall and allowed the XV-15 to operate at speeds of 550 kph (345 mph TAS). This is the second of the two XV-15s built by Bell under a …
