ANNULAR COMBUSTION CHAMBER FOR TURBO-MACHINE WITH IMPROVED INTERNAL MOUNTING FLANGE

摘要

FIELD: machine building.;SUBSTANCE: annular combustion chamber for turbo-machine contains an inner annular wall and an outer annular wall, joined by a frontal wall. The inner and outer walls are extended in the direction of flow gases by an internal mounting flange and an external mounting flange, attached respectively to the inner cover and outer cover of the turbo-machine housing for holding the combustion chamber. The internal flange has openings for inlet of cooling air into the high-pressure turbine of the turbo-machine. Openings for letting in cooling air on the internal flange lie on at least two rows in checkered order.;EFFECT: invention is aimed at increasing resistance to vibrations resulting from combustion of the air-fuel mixture in the combustion chamber.;5 cl, 5 dwg
