FIELD: engine building.
SUBSTANCE: bypass turbofan engine afterburner combustion chamber comprises a housing with a heat shield installed therein with the cooling channel formation between them, diffuser, and the front-end device. Diffuser is formed by the chamber body and behind the turbine cuff. Front-end device includes rigidly fixed relative to the housing radial flame stabilizers and the annular flame stabilizer. Afterburner combustion chamber is additionally equipped with rigidly connected by the end face to the annular flame stabilizer outer diameter edge the annular shield with the formation between the annular and heat shields tapering in the main gas flow direction of the concentric annular channel. Annular shield is rigidly fixed relative to the heat shield.
EFFECT: invention is aimed at reduction in the thermal load on the heat shield, which increases its service life and increases the engine reliability.
