Abstract:
1. An air cooled turbine airfoil comprising: a pressure side wall and a suction side wall; a serpentine flow cooling circuit formed within the pressure side and suction side walls to provide cooling for the airfoil; a radial extending cooling air channel formed adjacent to a trailing edge region of the airfoil; a plurality of serpentine flow channels formed within the trailing edge region of the airfoil and connected to the radial extending cooling air channel; the serpentine flow channels having a plurality of radial upward legs and a plurality of radial downward legs; the airfoil includes a plurality of modules extending along the trailing edge of the airfoil; each module being separated by a partition rib; and, each module having a plurality of serpentine shaped ribs to form a plurality of serpentine flow channels within the trailing edge region of the airfoil.
