COMBUSTION CHAMBER OF MICROTURBO-CHARGED UNIT Russian patent published in 2015 - IPC F02C3/14 

FIELD: engines and pumps.

SUBSTANCE: gas-turbine engine includes an engine housing with a shaft assembly fixed in a turning manner on a bearing assembly, a combustion chamber enclosed in the engine housing, a compressor connected to the assembly for rotation about the longitudinal axis, a turbine attached to the shaft assembly for rotation about the above longitudinal axis, a fuel feeding system for supply of a fuel-air mixture to the combustion chamber. The fuel feeding system includes a fuel reflector unit fixed in a turning manner on the shaft assembly, including the fuel reflector housing and an impeller of the fuel reflector. The impeller of the fuel reflector includes a discharge channel hydraulically connected to the combustion chamber. A fuel deflector is rigidly fixed inside the engine housing. The fuel deflector has an inner surface located at a certain distance and opposite the outer surface of the fuel reflector housing, thus forming a fuel feed channel. The latter has an inlet hydraulically connected to a fuel line, is diverted along the longitudinal axis and ends with an outlet adjacent to the discharge channel of the above impeller of the reflector. The inner surface has a shaped surface formed with a number of concentric irregularities on it.

EFFECT: invention is aimed at improvement of economy and reduction of engine prime cost.
