PROBLEM TO BE SOLVED: To provide a turbine bucket having a bucket airfoil having an airfoil shape, having high aerodynamic, thermodynamic and mechanical properties. SOLUTION: This airfoil shape has a nominal profile according to the tables set forth in the specification. The X and Y coordinates are smoothly joined by an arc of radius R defining airfoil profile sections at each distance Z. The profile sections at the Z distances are joined smoothly with one another to form a complete airfoil shape. This airfoil profile results in improved efficiency and airfoil loading capability.
