FIELD: machine building.
SUBSTANCE: blade of a bladed wheel of a gas-turbine engine includes an aerodynamic shaped element having lower surface and a platform passing form one of the ends of the aerodynamic shaped element in the direction that is perpendicular in a whole to longitudinal direction of aerodynamic shaped element. Platform includes at least one air spraying channel and a groove passing along lower surface near at least the part of that surface, which is rear in flow direction. The groove passes at constant distance from lower surface and in close proximity to it. In that groove there is at least one air spraying channel.
EFFECT: higher cooling efficiency.
