Abstract:
1. A gas ejection cone for an aircraft turbojet, comprising: a hollow main body defining, on the outside, a radially inner skin of an annular primary flow channel of the turbojet; and a device generating turbulence of the primary flow, mounted so as to move on the main body so as to be able to be displaced from an extracted position in which the device projects toward downstream in relation to a downstream end of the hollow main body, and a retracted position in which the device is retracted into the hollow main body, and vice versa, the device generating turbulence comprising a cylindrical support body having an axis parallel to an axis of the ejection cone, and at least one fin supported by the cylindrical support body, wherein the hollow main body comprises a slot for the housing of each fin of the device for generating turbulence in its retracted position.
