ANNULAR COMBUSTION CHAMBER OF GAS TURBINE ENGINE AND METHOD OF ARRANGEMENT OF WORKING PROCESS THEREIN Russian patent published in 2020 - IPC F23R3/50 

FIELD: machine building.

SUBSTANCE: annular combustion chamber of gas turbine engine includes external and internal walls, which are made in the form of curvilinear surfaces, corner flame stabilizer. On the angular flame stabilizer rear side there is profiling in the form of two curvilinear surfaces. Outlet part of combustion chamber includes gas flow collector, which is a channel formed by collector blades and walls of combustion chamber. Gas collector consists of a cascade of separate outlet branch pipes restricted with housings which, as they approach the turbine, are combined into a single annular channel.

EFFECT: invention is aimed at possibility to change excess air factor in annular combustion chamber with transverse system of reverse current zones formation and preventing formation of stagnant zones.
