Abstract: An air cooled turbine blade with a trailing edge cooling circuit that is formed by casting the airfoil with a pressure side trailing edge lip being oversized, and then machining away material from the pressure side wall to leave a pressure side bleed slot with a smaller (t/s) ratio than can be formed by casting alone. In another embodiment, the airfoil is cast with a trailing edge exit hole, and then the material on the pressure side wall in the trailing edge region is machined away to leave a pressure side bleed slot instead of an exit hole.

Abstract: An air cooled turbine airfoil with a leading edge region having rows of diffusion slots opening onto the airfoil surface. Each diffusion slot is connected to a plurality of metering and diffusion holes that meter the cooling air flow and provide for a first diffusion of the cooling air. The metering holes and diffusion holes are angled in order to improve the cooling effectiveness of the passages. The metering and diffusion holes and diffusion slots are formed from a metal printing process that can produce features that cannot be formed from an investment casting process that uses a ceramic core.

Abstract: A turbine blade having an internal cooling system with incremental serpentine cooling channels in near walls forming an outer surface of the turbine blade is disclosed. The turbine blade may be formed from an internal structural spar that is covered with a thermal skin. The incremental serpentine cooling channels may be cut into the outer surface of the spar to which the thermal skin may be attached. The incremental serpentine cooling channels may be formed from two or more serpentine cooling channels aligned along an axis that extends generally spanwise throughout the turbine blade. A row of incremental serpentine cooling channels may extend from a root to a tip of the blade, but a single incremental cooling channel does not.

Abstract: A cooling fluid feed system for a turbine engine for directing cooling fluids from a compressor, through one or more impellers, and into row one turbine vanes and one or more rows of turbine blades for increasing the cooling capacity of the turbine vanes and blades. Such a configuration increases cooling capacity, which in turn increases the capacity for growth within the turbine engine, creates a larger cooling fluid to gas side pressure differential and reduces amount of bleed off of cooling fluids from the compressor, thereby increasing efficiency of the turbine engine.
