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 ...
1. An aircraft jet engine, comprising: a nozzle including a nozzle outlet to eject a gas stream;at least one duct with a downstream end which opens downstream at the nozzle outlet so as to eject at least one fluid jet to interact with the ejected gas stream; andat least one pulsation means for ejecting a respective fluid jet from said at least one fluid jet at the nozzle outlet, the at least one pulsation means including two cowls which face each other along a first axis, the two cowls connected together defining at least part of a recess, the recess div...
