Abstract
An exhaust nozzle used in conjunction with an upper surface blown aircraft for directing the exhaust gases from the aircraft engine over the wing and flap surfaces of the aircraft. The nozzle can occupy two positions. The first position, for use in cruise mode, directs the exhaust gases rearwardly in a normal manner. In the second position, used for takeoff and landing, the nozzle outlet area is slightly increased and the nozzle tilted to direct the exhaust gases rearwardly and downwardly across the wing and flap surfaces thereby increasing lift due to the Coanda effect.
