Abstract:
A cooling system for a turbine airfoil of a turbine engine having suction side platform cooling channels and pressure side platform cooling channels for cooling hot spots in a platform attached to a turbine blade. The cooling system may include one or more pressure side platform cooling chambers having a diffusion slot for cooling downstream platforms on the suction side of the turbine blade. The diffusion slots reduce the velocity of the cooling fluids released from the platform to increase the capacity of the film cooling of downstream platforms.
