Abstract
A diffusion cone for the rear part of a jet engine has a base and, on an opposite side, a truncated tip defining an annular trailing edge, and comprises a flame-holder ring with a cross section comprising an external branch and an internal branch which are connected to one another on the base side and such that the external branch extends around the internal branch, whereby the external and internal branches delimit between them an internal space opening on the opposite side to the base. One of the branches is made up of the annular trailing edge. The flame-holder ring comprises at least one fuel inlet designed to let fuel into the internal space. Such a flame-holder ring makes it possible to ensure and to control the propagation of the flame within the afterburner channel.
