FIELD: gas turbines.
SUBSTANCE: cooling the blades of high-temperature gas turbines. The cooled turbine blade includes an internal cavity with the possibility of cooling air entering it and holes for air outlet. On the inner surface of the blade there is a honeycomb and socket surface, wherein the blade is made by stamping from a sheet metal plate with a constant width, while the spherical cavities, honeycomb surface, holes are made at the stage of preparing the plate before stamping.
EFFECT: increasing the cooling intensity of the blade while simplifying its manufacture.
