FIELD: mechanical engineering; gas-turbine engine. SUBSTANCE: proposed gas-turbine engine has main gas duct passing through engine and device to supply cooling air from compressor section of gas-turbine engine to profile part of blade. Flanges of blades are provided with holes arranged below inner channel in direction of gas flow to let pass air used for cooling the flanges by directed flow into profile part below inner channel to increase pressure in rear zone of profile part. EFFECT: improved temperature gradient in height of blade profile part. 3 cl, 3 dwg
