Abstract

An aircraft engine having a longitudinal axis, including a wall surrounding a gas stream that is ejected at a downstream end of the wall along the longitudinal axis, wherein a plurality of conduits distributed at the periphery of the downstream end of the wall are each capable of ejecting, via an outlet orifice, a fluid jet in the form of a sheet, in such a way that the jets thus ejected each form a fluid perturbation around the ejected gas stream.
