ABSTRACT:
A noise suppression system for a jet engine of an aircraft having a device for blocking a flow of exhaust gases down the exhaust nozzle of the engine, and a device for separating the exhaust gases into a plurality of exhaust streams spaced a predetermined distance apart and having a smaller cross-sectional area than that of the original flow of exhaust gases. The separating device also directs the exhaust streams into the ambient air from points outside the periphery of a nacelle covering the engine. The aforementioned predetermined distance separating the exhaust streams, and the cross-sectional area of the exhaust streams, are chosen so that engine noise is shifted to a higher frequency spectrum than that of the original flow of exhaust gases, and then substantially dissipated within a short distance of the aircraft.
