Abstract
The invention is a short/vertical takeoff and landing aircraft. In detail, it comprises an airframe having aerodynamic lift and flight control surfaces. An engine is mounted in the airframe in a reversed position having the inlet facing toward the rear of the aircraft and the exhaust nozzle assembly, having a pair of exhaust nozzles, facing toward the front. The exhaust nozzles extend outward from the sides of the aircraft and are rotatable from a vertically downward position to provide upward thrust to a horizontally rearward direction to provide forward thrust. The thrust axis when in the vertical position is approximately through the center of gravity. A generally U-shaped engine inlet duct is mounted in the airframe having an inlet opening facing forward and an outlet coupled to the inlet of the engine.
