Abstract:
An aircraft suited for vertical flying motion comprising:a cabin, containing a prime mover for powering a rotatable rotor assembly, wherein the prime mover imparts a torque to the cabin during flying operation;a rotatable shaft, extending upwardly from the cabin, driven by the prime mover;a rotor assembly, mounted above the cabin, connected to the shaft, and adapted to rotate in a desired direction relative to the cabin; comprising a truncated cone shaped top having a central inlet opening; a circular bottom spaced apart from the top; and, rotor vanes, running radially between the top and the bottom of the rotor assembly, from vicinity of the central inlet opening to vicinity of the outer circumferences of said top and bottom;wherein, the exterior circular edges of the top and the bottom form a downward facing annular nozzle for discharge of air from within the rotor assembly;the combination of top, bottom and vanes forming an air-moving impeller so that when the top assembly is rotated, air is flowed through the inlet opening of the top, radially outward past the vanes, and then downward through said nozzle; and,means for countering said torque, on the cabin.
