ABSTRACT:
A turbine blade for a turbine engine having a leading edge cooling system formed from a suction side cooling channel and a pressure side cooling channel. Cooling fluids flow into the leading edge cooling channels through impingement orifices that meter cooling fluid flow. The cooling fluids may form vortices in the cooling channels before being released from the turbine blade through gill holes. The cooling fluids then form a boundary layer of film cooling fluids on an outer surface of the turbine blade.
