An exhaust flow nozzle for use with a jet engine. The exhaust flow nozzle includes a beveled downstream edge portion that helps to direct noise generated by the jet engine upwardly away from a ground surface during takeoff and landing operations. One specific embodiment makes use of a linearly moveable flow altering component that is positioned outside the final flow nozzle. When the flow altering component is in its retracted position it has no effect on the exhaust flow leaving the flow nozzle. Alternative embodiments involve the use of varying edge sh...
What is claimed is: 1. A mixed flow exhaust nozzle for a jet engine, comprising: a tubular final nozzle having a downstream edge portion through which exhaust flow from said jet engine exits said tubular final nozzle; a primary nozzle disposed within the tubular final nozzle; said downstream edge of said tubular final nozzle forming a non-linear edge; and wherein the non-linear edge comprises a beveled portion over a portion of said downstream edge, when viewing said downstream edge from a side view. 2. The mixed flow exhaust nozzle of claim 1, where...
