FIELD: engine building.
SUBSTANCE: invention relates to gas turbine engines. Annular combustion chamber of a gas turbine engine comprises a body, a nozzle plate with nozzles, a flue tube with an external flue tube casing, an annular gap between the external flue tube casing and the combustion chamber body, in communication with the cavity of the heat pipe; the flue tube is provided with holes for the supply of cooling air and pockets for air supply, and is configured to swirl the combustion products relative to the longitudinal axis of the combustion chamber. The possibility of swirling the combustion products is provided by the simultaneous placement of the nozzles on the nozzle plate and the holes for the supply of cooling air at an angle to the plane passing through the longitudinal axis of the annular combustion chamber.
EFFECT: reduced circumferential unevenness of the temperature field at the output of the combustion chamber.
