Abstract

An airfoil includes internal cooling air passages arranged in a serpentine manner with one or more radially outward and radially inward extending passages. The passages are in fluid connection through turns of approximately 180°. The turns near the platform of the airfoil connecting a radially inward extending passage with a radially outward extending passage are realized by a root turn defined by the passage sidewalls, which extend radially inward to the radially inner end of the root section of the airfoil, and by an end plate attached to the radially inner ends of the walls.
