The Bell Boeing Quad TiltRotor (QTR) is a proposed four-rotor derivative of the V-22 Osprey tiltrotor developed jointly by Bell Helicopter and Boeing. The concept is a contender in the U.S. Army’s Joint Heavy 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.
