PROBLEM TO BE SOLVED: To deflect the exhaust gas stream of an aircraft engine from an aircraft's fuselage structure. SOLUTION: Nozzles (3, 5) for discharging high velocity air are positioned on each side of an exit of an aircraft engine duct (1) exit. High velocity air is discharged tangential to an outer surface of each nozzle (3, 5) and follows the contour thereof. Each nozzle (3, 5) is positioned so that when the high velocity air separates from the outer surface of the respective nozzles (3, 5), it flows outwardly relative to the aircraft's fuselage structure. The high velocity air from the nozzle (3) closest to the aircraft's fuselage structure impinges on the exhaust gas stream (35, 57), deflecting the stream in a direction (43) away from the fuselage. The high velocity air from the nozzle (5) furthest from the fuselage creates a low pressure area which deflects the exhaust gas stream (35, 37) away from the fuselage. In combination, the two nozzles (3, 5) deflect the exhaust gas stream (35, 37) away from the fuselage to some extent. COPYRIGHT: (C)2005,JPO&NCIPI
