STATOR OF GAS TURBINE Russian patent published in 2018 - IPC F01D11/24 F01D25/14 

FIELD: turbines or turbomachines.

SUBSTANCE: invention relates to stators of gas turbines of gas turbine engines for aviation and ground applications. Stator of a gas turbine, the outer shell of which contains radial annular ribs forming annular air cavities, connected to each other by air channels. Air channels in the outer stator housing are made perpendicular to the outer surface of the outer shell, interconnected through an air cavity formed by an installed bypass flange on the outer surface of the outer stator housing. And L/d=4…10; L/M=0.5…4, where d is the air channel diameter; L – axial length of the flange; M is the flange size in the circumferential direction.

EFFECT: allows to increase reliability and reduce the cost of the stator of a gas turbine by performing air cooling air supply channels perpendicular to the outer surface of the outer stator housing.
