COOLED COMPOSITE SHEETS FOR GAS TURBINE Russian patent published in 2017 - IPC F01D5/18 

FIELD: metallurgy.

SUBSTANCE: laminated sheet for a gas turbine component includes the first and second coating layers and the first intermediate layer. The first coating layer, second coating layer and the first intermediate layer are stacked together one on top of the other. The first intermediate layer is disposed between the first coating layer and the second coating layer. The first intermediate layer comprises at least one first elongated through hole, through which cooling fluid can flow. Wherein the first intermediate layer comprises at least one additional first elongated through hole which is located at a distance from the first elongated through hole. The cooling fluid can flow through the mentioned additional first elongated through hole and in the plane of the laminated sheet. The first elongated through hole and the first additional elongated through hole are connected so that the cooling fluid can move between the first elongated through hole and the additional first elongated through hole.

EFFECT: reduced cost and lowered complexity of manufacturing the laminated sheet.
