ABSTRACT:
A lift generating method and apparatus for aircraft is provided which generates lift in forward flight, in vertical flight or while hovering. A disk (24) is positioned between first and second counterrotating blade assemblies (22 and 36). The disk (24) generates lift in vertical flight or while hovering due to radial flow of air over an upper surface (28) thereof. In forward flight, the disk (24) functions as a fixed wing to generate lift. The assemblies (22 and 36) may be rotated to provide equal and opposite torques so that a torque compensating tail rotor is unnecessary.
