<p>Nozzles (3, 5) for discharging high velocity air are positioned on either side of an aircraft engine exhaust duct (1) exit. High velocity air is discharged tangential to an outer surface of each nozzle (3, 5) and follows the contour thereof. The nozzles (3, 5) are 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, 37), deflecting the stream away from the fuselage (43). 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 a significant degree.</p> |
