Quad Tilt Rotor
From Wikipedia, the free encyclopedia
A Quad Tilt Rotor (QTR) is a larger four rotor version of a Tiltrotor aircraft. It has 2 sets of fixed wings and 4 tilting rotors mounted at the tips of the wings. The program has been nicknamed the V-44 Tiltrotor for the four Tiltrotor version and V-66 Tiltrotor for the six tiltrotor version. These poly-tiltrotor aircraft have also been called "The Flying Freight Train" for their large capacity almost the size of a railcar. These may carry as many as 100 passengers or troops or heavy cargo over 50,000 pounds. They would use uprated versions of the tiltrotor engines used for the V-22 Osprey. These designs have been seen in Popular Science and Popular Mechanics.
