ABSTRACT:
A method and apparatus for selectively generating a noise suppressing hot gas shield are described. A portion of the jet engine exhaust flow is selectively directed to a nozzle which at least partially surrounds the circumference of the jet engine exhaust. Prior to exiting the nozzle the flow is passed through a pressure, and therefore density, loss producing device to provide a shield flow of optimum noise suppression properties.
