Role	Cargo tiltrotor Type of aircraft
Manufacturer	Bell and Boeing
Status	Study
Developed from	Bell Boeing V-22 Osprey

The Bell Boeing Quad TiltRotor (QTR) is a proposed four-rotor derivative of the Bell Boeing V-22 Osprey developed jointly by Bell Helicopter and Boeing. The concept is a contender in the U.S. Army's Joint Heavy Lift program (a part of Future Vertical Lift program). It would have a cargo capacity roughly equivalent to the C-130 Hercules, cruise at 250 knots, and land at unimproved sites vertically like a helicopter.^[1]
