Abstract
Disclosed is a propulsive lift mechanism which improves the short takeoff and landing capabilities of an aircraft by generating transverse thrust lift augmentation by exhausting gasses ported from the main exhaust through a nozzle, close behind and parallel with the trailing edges of the wings of the aircraft, which transverse jet together with thrust vectoring means of the aircraft, provide improved aerodynamic lift on the wings of the aircraft. The transverse nozzle, having means adjustable for creating reverse thrust, and optionally for discharging said exhaust gasses with a swirling motion, may provide both increased circulation of air over the wings as well as improved flow separation control on the trailing edge flaps of the wings. Exhaust gas from the jet engine of the aircraft is ported to the transverse nozzles by flap valves operating in the exhaust of the jet engine.
