Beschreibung
Zusammenfassung:A jet engine comprising a primary flow of hot gas and a secondary air flow which are separated, up to the entrance to an afterburner duct provided with annular flame-holders by a wall which is supported, on the upstream side, on the rear end of a turbine casing and which corrugates progressively up to a rear edge, the said primary flow or secondary flow, or both, being affected, upstream of the said wall, by disturbances which change the velocity ratio of the two flows in areas located downstream of the disturbances, in which the radius of the said rear edge of the wall is relatively great in the areas in which the ratio between the velocity of the primary flow and the velocity of the secondary flow is relatively small, and vice versa.
