STATOR THERMAL SHIELD FOR GAS TURBINE, GAS TURBINE WITH SUCH STATOR THERMAL SHIELD AND STATOR THERMAL SHIELD COOLING METHOD Russian patent published in 2019 - IPC F01D11/24 

FIELD: machine building.

SUBSTANCE: stator thermal screen for a gas turbine comprises a hot gas flow channel, a first surface configured to position a gas turbine facing the hot gas flow channel, a second surface, opposite to first surface, cooling channels intended to direct cooling fluid medium from second surface to first surface, cavities located on first surface to receive cooling fluid medium from at least part of cooling channels. At least a part of cavities each have at least two corresponding cooling channels opening into it. At least two corresponding cooling channels are inclined to each other. Each of the at least two corresponding cooling channels has an inlet for receiving a cooling fluid medium on the second surface and an outlet for discharging a jet of cooling fluid into the corresponding cavity. At least two corresponding cooling channels are located so that jets of cooling fluid medium, released from said at least two corresponding cooling channels, interact, providing swirling of cooling fluid medium in cavity.

EFFECT: invention is aimed at improving cooling efficiency.
