ABSTRACT:
An aircraft comprising an aerodynamic annulus and a fuselage coupled to the annulus by electromagnetic means to permit rotation of the annulus relative to the fuselage without mechanical engagement upon a "frictionless" bearing. Jets mounted on the annulus rotate the annulus to produce a gyroscopic precession. One or more jets or driven propeller units mounted on the fuselage drive the craft in a selected direction. Direction of the fuselage, and hence the aircraft, may be provided by computer control of the fuselage jets or jets or by means of a rudder. Pivotal jets mounted on the annulus and/or fuselage together with retractable flaps on the annulus provide lift for vertical take-off and hovering.
