ABSTRACT:
A turbine blade with a cooling circuit that includes three separate 3-pass serpentine flow cooling circuits that each flow in the aft direction of the blade. Each of the three 3-pass serpentine circuits includes a first leg on the pressure side of the blade with a row of film cooling holes to discharge cooling air to the pressure side surface of the blade. The first and the second 3-pass serpentine circuits each include second and third legs located on the suction side of the blade, and the third legs include a row of film cooling holes to discharge cooling air onto the suction side wall surface. The third 3-pass serpentine circuit includes a second leg on the suction side and a third leg aft of the first and second legs and positioned between both the pressure side and suction side walls. Cooling air for a leading edge cavity and showerhead arrangement is supplied from the first leg of the first 3-pass serpentine circuit. The third leg of the third 3-pass serpentine circuit includes a row of exit holes to discharge cooling air out the trailing edge of the blade.
