COOLED WALL OF TURBINE COMPONENT AND COOLING METHOD OF THIS WALL Russian patent published in 2019 - IPC F01D5/18 

FIELD: machine building.

SUBSTANCE: cooled wall of turbine component includes the first layer of channels for cooling agent, which is located along side of wall facing to flow of hot gas, at that the first layer has a serpentine shape, and each channel has inlet and outlet. Second layer of coolant channels is located further from the flow of hot gas than the first layer. Each channel of the second layer has an inlet and an outlet. Release of each channel of the first layer is fluidly communicated with the corresponding inlet of the associated channel of the second layer, creating a bend to change the direction of the coolant leaving said channel of the first layer when the second layer gets into the channel. Serpentine form of channels of the first layer forms multiple bends in longitudinal direction of the first layer, and channels of the first layer have a repeating pattern of curves along axial extension of channels of the first layer.

EFFECT: invention is aimed at increasing service life of heat shield and tips of blades, reducing consumption of cooling agent.
