Abstract:
1. A turbine blade including an airfoil, said airfoil having an uncoated nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in millimeters in Table 1 wherein Z is a perpendicular distance from a plane containing said X and Y values with said Z value commencing at zero in said X, Y plane at a radially innermost aerodynamic section of said airfoil and X and Y are coordinate values defining said airfoil profile at each distance Z which, when connected by smooth continuing arcs, define profile sections at each distance Z, said profile sections at said Z distances being joined smoothly with one another to form the complete airfoil shape and wherein said airfoil shape is defined in an envelope within about 1% of a maximum Z value in a direction normal to any airfoil surface location.
