Abstract:
A high-speed vertical take-off and land aircraft comprising:a disk-shaped body; a jet engine supported by said body; a feed duct for receiving and redirecting the exhaust gases from the jet engine; an annular rotor having a rotatable fan assembly concentric with the body; said fan assembly including a plurality of blades to provide vertical lift for said aircraft; said blades being airfoil-shaped and operative to scoop ambient air causing a downwash to maximize the lifting forces; and a nozzle ring on said rotor providing an annular nozzle array separate from said blades for receiving the exhaust gases from said feed duct and ejection to generate reaction thrust to said nozzle ring and said fan assembly, for rotation thereof, whereby enhanced primary lift for said aircraft is provided.
