摘要： 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 its speed by varying the volume contained in the recess.

摘要： The invention relates to an aircraft jet engine comprising a nozzle (2) intended to eject a gas stream, and a system for reducing the noise (3) generated by the ejection of the gas stream.This system comprises several ducts (11a) which each, on the one hand, are connected upstream to a recess divided into several chambers and, on the other hand, open, downstream, at the outlet of nozzle (2). 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 (12) for the fluid jet which brings about its ejection at the nozzle outlet and/or modulates its speed by varying the volume contained in the recess.The system is configured in particular for balancing static pressures between the chambers.
