초록

An aircraft jet engine comprising a nozzle to eject a gas stream, and a system for reducing the noise generated by the ejection of the gas stream. This system comprises several ducts which each are connected upstream to a recess divided into several chambers and open, downstream, at the outlet of nozzle. In this way, each duct ejects a fluid jet deriving from the recess and which interacts with the gas stream of the engine. The system also comprises a pulsation means for the fluid jet which brings about its ejection at the nozzle outlet and/or modulates ...
