ABSTRACT:
A flying disc capable of vertical takeoff, hovering, or powered horizontal flight. The disc includes a discoidal wing that is circular and includes a convex surface on an upper side and a concave lower surface. The wing also includes an inward leading edge that defines a circular opening centered on an upright central axis. The arcuate surfaces converge at the leading edge and at an outer concentric trailing edge. The discoidal wing is freely rotatable on a central support structure that also supports a cockpit. Two sets of turbine blades are affixed to the discoidal wing adjacent the leading edge. Thrust producing engines are mounted to the central support structure to direct thrust radially outward through the turbine blades. This results in rotation of the discoidal wing and produces lift. The angle of thrust may be adjusted such that the thrust is directed only across one or the other set of turbine blades or any selected variation between extreme positions to change the lift characteristics. A set of compressor blades is provided about an upper surface of the disc adjacent the cockpit. The compressor blades rotate with the discoidal wing to receive and direct air downwardly into the central support structure. They supply combustion air for the engine and reduce the air pressure above the disc. Horizontal thrust engines are supplied below the concave wing surface to provide horizontal thrust. Steering and rotational stabilization of the cockpit and central support structure is provided by a thrust diverting mechanism.
