초록

A method for operating a gas turbine engine includes channeling compressed air from the gas turbine engine to a noise suppression system, and selectively operating the noise suppression system such that air discharged from the noise suppression system generates a plurality of flow control mechanisms in the gas turbine exhaust flowpath.

청구항

What is claimed is: 1. A method for operating a gas turbine engine, said method comprising: positioning a noise suppression system comprising a manifold and a plurality of tubes within the gas turbine engine such that the plurality of tubes are coupled azimuthally around an outer periphery of a nozzle; coupling one end of each of the plurality of tubes to the manifold and coupling an opposite end of each of the plurality of tubes to the nozzle such that the plurality of tubes each extend away from the manifold; channeling compressed air from the gas tur...
