Abstract (en)
[origin: EP2500458A1] The blade has an internal cooling cavity (24) extended in a radial direction within the blade. The internal cooling cavity is extended along a rear edge (14) of the blade. The rear edge is provided with coolant discharge openings (26) that are extended along the rear edge. Swirl generators (32) are formed on an inner surface (30) at a pressure side (18) and/or a suction side (16) of the blade. The generators are radially arranged at a distance to the internal cooling cavity, are parallel to the cooling cavity and are extended in proximity to the discharge openings.
