A device for reducing engine exhaust noise in an aircraft engine includes a number of oscillating jets which direct an oscillating flow into the engine exhaust. The oscillating jets are connected via channels to a turbomachinery source of high pressure gas, where the source is located upstream from the engine exhaust portion. The high pressure gas passes through the oscillating jets, which have a nozzle with a triangular shaped orifice and an exhaust pipe, and exits the oscillating jets having a oscillating flow. The oscillating flow mixes with the engin...
What is clamed is: 1. A device for reducing jet engine exhaust noise, comprising: at least one oscillating jet coupled to an engine exhaust portion, said oscillating jet comprising: a nozzle with a triangular shaped orifice formed therein, and an exhaust pipe coupled to said nozzle, wherein a flow of gas passes through said triangular shaped orifice and exits from said exhaust pipe, having an oscillating flow, and wherein at least a portion of said gas from said exhaust pipe mixes with engine exhaust passing through said engine exhaust portion. 2.
