| description | A turbine blade for a gas turbine engine may include an outer, peripheral wall extending along a suction side and a pressure side of the blade from a leading edge to a trailing edge of the blade and from a root end to a tip end of the blade, a substantially vertical bifurcating internal wall extending between the leading edge and the trailing edge of the blade in between the suction side and the pressure side of the blade, a plurality of pressure side cooling fluid passages defined between the peripheral wall on the pressure side of the blade and the bifurcating internal wall and extending at least part way from the root end to the tip end of the blade, and a plurality of suction side cooling fluid passages defined between the peripheral wall on the suction side of the blade and the bifurcating internal wall and extending at least part way from the tip end to the root end of the blade. At least one of the pressure side cooling fluid passages may receive fresh cooling fluid from a cooling fluid inlet opening at the root end of the blade and direct the cooling fluid radially upwardly toward the tip end of the blade, across a top side of the bifurcating internal wall, and down through at least one of the plurality of suction side cooling fluid passages. |
