Gas turbine engine jet noise suppressor

摘要

The jet noise suppressor includes a nozzle (20; 30), having an arrangement thereon of trapezoidal tabs (40) disposed on the downstream end of the nozzle (20; 30), the tabs (40) having a length (L) and the angular offset with respect to the engine flow such that mixing occurs primarily at the interface of the engine flow and the ambient air. In addition, various construction details are developed for the tabs including tabs that are trapezoidal with tapered sides such that the tabs minimize adverse impact to engine performance. <IMAGE>
