A method and device for reducing the amount of noise generated by a supersonic jet engine is provided. The method creates an envelope of air around the supersonic jet exhaust. The temperature and velocity of this envelope is controlled to eliminate or reduce the formation of noise making Mach waves.
A method of avoiding the generation of Mach waves from an operating jet engine, said method comprising the steps of: (a) intaking air into a first end of a jet engine; (b) heating a first stream of said air to a first temperature; accelerating said first stream of said air to supersonic speeds and expelling said first stream out a second end of said jet engine; (c) heating a second stream of said air to a calculated second temperature; (d) maintaining the velocity of, accelerating or decelerating said second stream of air to a predetermined air velocity;...
