ABSTRACT:
A turbine blade used in a gas turbine engine, the blade having a dual triple pass serpentine flow cooling circuit to provide cooling to the blade. A first triple pass serpentine flow circuit includes a first leg located on the pressure side, a second leg located on the suction side and directly opposed to the first leg, and a third leg located aft of the first and second leg and between the pressure side and suction side walls. A showerhead cooling arrangement is supplied cooling air through metering holes connected to the third leg. A second triple pass serpentine flow circuit is located downstream from the first serpentine flow circuit and includes a first leg on the pressure side of the blade, a second leg on the suction side and directly opposed to the first leg, and a third leg downstream from the first and second leg and between the pressure side and suction side walls, the third leg including trailing edge exit cooling holes.
