摘要： Aircraft jet engine with a longitudinal axis (XX'), comprising a wall (30) enclosing a gas flow which is ejected from a downstream end of the wall in the longitudinal axis, several ducts (32, 34, 36, 38, 40, 42, 44, 46) being distributed around the periphery of the downstream end (30a) of the wall each comprising a terminal section, provided with an outlet opening. Each duct can eject a fluid jet through the outlet opening thereof, characterised in that the ducts are designed to eject the fluid jets essentially parallel to each other, each fluid jet ejected through the corresponding outlet opening (32b) forming a lateral angle (d) with the longitudinal axis (XX') in a projection view in a plane with the longitudinal axis.
