Abstract
An article of manufacture is disclosed. The article may have a nominal profile generally in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A. X and Y may correspond to distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the airfoil profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.

An article of manufacture, the article having a nominal profile generally in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the airfoil profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.
A rotor blade including an airfoil, the airfoil having a nominal profile generally in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the airfoil profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.
A compressor comprising:
- a rotor wheel;
- and
- a plurality of rotor blades mounted to the rotor wheel, each of the plurality of rotor blades including an airfoil, the airfoil having a nominal profile generally in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the airfoil profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.
