Disposed at or toward the trailing edge of one or more nozzles associated with a jet engine are injection ports which can selectively be made to discharge a water stream into a nozzle flow stream for the purpose of increasing turbulence in somewhat of a similar fashion as mechanically disposed chevrons have done in the known art. Unlike mechanically disposed chevrons of the known art, the fluid flow may be secured thereby increasing the engine efficiency. Various flow patterns, water pressures, orifice designs or other factors can be made operative to pr...
Having thus set forth the nature of the invention, what is claimed herein is: 1. A jet noise reduction system for use with a jet engine, said jet engine having a first nozzle with a trailing edge, said system comprising:a fluid supply;an injector operably coupled to an orifice proximate to the trailing edge of the first nozzle;said jet noise reduction system having at least a first configuration in which said fluid supply is in fluid communication with said injector and said orifice to thereby direct a stream of fluid with a momentum into a first flow st...
