The present invention provides a single seat aircraft having the capabilities of vertical takeoff, landing and hovering operations utilizing the X-Wing as a conventional helicopter rotating wing. After transition to forward flight following takeoff, the rotating wing is stopped and becomes a fixed wing of “X”configuration. The aircraft utilizes two engines within the fuselage, one engine being positioned vertically above the other along the longitudinal axis of the aircraft, the particular arrangement of engines allowing aircraft size and weight to be substantially reduced.

In an X-wing helicopter aircraft, a fuselage defining a longitudinal axis of said aircraft, a rotor assembly mounted on said fuselage for rotation at speeds below a predetermined value during helicopter phase operations and adpated to be stopped above said value to provide fixed X-wing airfoil, supplemental fixed wings attached to the fuselage, first, upper and second, lower jet engines mounted vertically one above the other and aligned vertically with respect to the longitudinal axis of the fuselage to provide symmetric and redundant flight control functions including yaw and pitch control, each of said engines providing a jet stream emanating therefrom rearwardly of said fuselage, said fuselage having a tail section including upper and lower exhaust nozzles through which said jet streams pass in straight lines, said nozzles each including means for controlling the direction of ejection of portions of the respective jet stream from said aircraft including upper engine movable upper and lower vectoring flaps and upper engine movable, port and starboard vectoring cascades, said cascades being equally proximate said upper engine jet stream, and lower engine movable upper and lower vectoring flaps and lower engine movable, port and starboard vectoring cascades, said lower engine cascades being equally proximate said lower engine jet stream, movement of said vectoring flaps in unison serving as pitch control for said aircraft, movement of vectoring flaps to close the nozzle serving as a nozzle blocker to activate the vectoring cascades for yaw control, movement of said cascades to open either port or starboard serving as primary yaw control, the movement of said vectoring flaps and cascades being equally functional in a lateral direction during helicopter phase maneuvers for either dual or engine-out operations.
