GAS TURBINE COMBUSTION CHAMBER Russian patent published in 2025 - IPC F23R3/28 F23R3/50 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to gas turbine engine building, in particular to designs of combustion chambers of gas turbine engines serving for drive of electric generator or supercharger of gas compressor unit. Combustion chamber of gas turbine engine, containing housing, on bosses of which fuel injectors are fixed with flanges, nozzle of the nozzle is installed in the opening of the swirler housing, which is included in the burner, fixed in the annular head of the flame tube by means of a threaded nut, plugs are installed in the rear part of the nozzles, characterized by that the nozzle nose has a hollow cylindrical section passing through the fillet into the larger diameter sprayer with a chamfer at the end, at the beginning of the sprayer the holes are arranged perpendicular to the axis of the nozzle of the nozzle, in the centre of the output part of the sprayer there is a hole, holes on the chamfer are located perpendicular to the angle of the chamfer, the diameter of the opening of the swirler body is greater than the diameter of the sprayer, annular channel is formed between the hole of the swirler body and the nozzle, plug is locked by means of locking plate having annular groove, one antennae of the locking plate are bent on the edge of the plug, and the other ones – on the nozzle body, in the rear part of the nozzle there is an annular groove with a groove in which a sealing gasket is installed, on the other side of the sealing gasket a metal ring with a groove is installed, located in the annular groove of the locking plate, compensation plates are installed in the joint between the casing bosses and the fuel injector flanges, the rings are attached to the ring head by means of welding.

EFFECT: higher reliability of combustion chamber and, consequently, engine life, simplified assembly and repair and reduced emissions of harmful pollutants.
