Abstract: A gas turbine blade including a root and an air foil with a leading edge and a trailing edge, a cooling air channel system extending from a cooling air opening in the root via a winding serpentine channel to a trailing edge channel at the trailing edge including an air outlet at the trailing edge is provided. For efficiently cooling the trailing edge of the blade it is proposed that the cooling air channel system includes an air bypass channel connecting the cooling air opening in the root with the trailing edge channel bypassing the serpentine channel.
Abstract: A gas turbine blade including a root, an airfoil with a leading edge and a trailing edge, a radial outer tip, and a pressure side and a suction side between the leading edge and the trailing edge, and a cooling air channel system extending from an air inlet opening in the root throughout the airfoil to a plurality of air outlets at the pressure side and the leading edge of the top of the tip of the airfoil.
