Improved High Effectiveness Cooled Turbine Blade

摘要

An air-cooled turbine blade (100) is provided having an airfoil (104) shape defined by a convex suction side wall (120), a concave pressure side wall (118), a leading edge (114), a trailing edge (116), a root (108) and a tip (122), the walls and the tip each including an interior surface that defines an interior with the root (108), the trailing edge (116) including a plurality of slots formed thereon. The blade (100) includes a suction side flow circuit formed therein comprising a forward and an aft flow circuit. The blade also includes a tip flow circuit extending along the tip interior surface to at least one of the trailing edge slots (124) and including a first and a second opening, the first opening in flow communication with the suction side forward flow circuit outlet, and the second opening in flow communication with a cross-over hole of the suction side aft flow circuit. Methods of manufacturing the blade are also provided.
