摘要： A gas exhaust nozzle for aircraft propulsion includes at least a downstream part with a trailing edge of chevron type formed of chevrons distributed along the periphery of the nozzle. Each chevron extends downstream between an upstream transverse plane and a downstream transverse plane with free edges oriented in two converging downstream directions and defining the trailing edge. The chevrons generate vortices at the boundary of the jet emitted by the nozzle. The gas exhaust nozzle includes a device to inject auxiliary gas jets upstream of the free edges of the chevrons in the main jet through orifices placed upstream of the upstream plane in such a way as to discharge upstream of the upstream plane of the chevrons to generate the vortices upstream of the free edges of the chevrons.
摘要翻译：用于飞行器推进的排气喷嘴至少包括具有由沿着喷嘴的周边分布的人字形形成的人字形的后缘的下游部分。每个人字形在上游横向平面和下游横向平面之间的下游延伸，其中自由边缘在两个会聚的下游方向上定向并限定后缘。人字纹在喷嘴发射的喷嘴的边界处产生涡流。气体排气喷嘴包括一个装置，用于通过设置在上游平面上游的孔口在主射流中的人字形自由边缘的上游注入辅助气体喷射，以便在人字形的上游平面的上游排放，以产生漩涡在人字纹的自由边缘的上游。

摘要： The invention relates to a variable-section flow mixer for a double-flow turbojet for a supersonic airplane, the mixer comprising a central body, a primary cover, a secondary cover, and a nozzle extending the secondary cover. The nozzle has a plurality of external-air admission openings having mounted therein lobes that are movable between two positions: a closed position in which they close the openings; and a deployed position in which they disengage said openings and deploy into the nozzle so as to allow external air to be admitted. All of the lobes present a common azimuth component in a common direction, and the mixer further includes a plurality of longitudinal grooves occupying at least a portion of the central body, all of the grooves presenting a common azimuth component in a common direction that is opposite to the direction of the azimuth component of the lobes.
