ABSTRACT:
A cooling system for a turbine blade of a turbine engine having a leading edge impingement cooling channel in series with one or more pressure and suction side impingement cooling channels. The turbine blade may include a double outer wall with impingement cooling channels positioned between the walls. The impingement cooling channels may be adapted to match heat localized loads and hot side gas pressures across the turbine blade to maximize the efficiency of the cooling system.
