Abstract
The present invention relates to a cooled turbine blade for a gas-turbine engine having at least one cooling duct () extending radially, relative to a rotary axis of the gas-turbine engine, inside the airfoil and air-supply ducts () issuing into said cooling duct, characterized in that the cooling duct () extends into the blade root () in order to generate close to the wall a cooling airflow moved at high circumferential velocity and radially in helical form and that in the area of the blade root () at least one nozzle-shaped air-supply duct () issues into the cooling duct () tangentially or with a tangential velocity component.
