FIELD: engine devices and pumps.
SUBSTANCE: gas turbine engine comprises a compressor, a casing between the compressor and the turbine, a turbine, a stand between the compressor and a combustion chamber with an annular air supply channel from the compressor to the combustion chamber, and a combustion chamber that has a flame tube, the outer and inner combustion chamber housings, blade swirlers of a charge, a nozzle with fuel supply pipe. At the entrance to the flame tube, a device is installed in the form of a tube with cone-shaped micro-swirls in the inner diameter in the form of a closed circle or a screw with a conical part and a rounded edge. This device is located behind the annular channel of air supply from the compressor to the combustion chamber.
EFFECT: stability, speed and completeness of fuel combustion in the flame tube.
