Cone of ejection of the gases for turbojet of 371 relates to a device for generation of turbulence of the primary flow limiting the jet noise

摘要

The present invention relates to an exhaust cone of the gases (8) for aircraft turboreactor, the cone with a main hollow body (30) externally defining a radially inner skin (36) of an annular channel of the primary flow. According to the invention, it also comprises a device (34) for the generation of turbulence of the primary flow limiting the jet noise, which is mounted movably on the main body so as to be able to be displaced from an extended position in which it projects towards the downstream direction with respect to a downstream end of the main hollow body, and a retracted position in which it is retracted into the main hollow body, and vice versa.
