Abstract

An article of manufacture having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A. 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 profile sections at the Z distances can be joined smoothly with one another to form a complete airfoil shape.

Claims

1. An article of manufacture, the article having a nominal profile substantially 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 profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.

2. An article of manufacture according to claim 1, wherein the airfoil shape comprises an airfoil.

3. An article of manufacture according to claim 2, wherein said airfoil shape lies in an envelope within ±

0.160 inches in a direction normal to any article surface location.

4. An article of manufacture according to claim 1, wherein the airfoil shape comprises a stator vane.

5. A compressor comprising a compressor wheel having a plurality of blades, each of said blades cooperating with a plurality of stator vanes, the plurality of stator vanes comprising an airfoil having an airfoil shape, said airfoil shape having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A, wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define the airfoil profile sections at each distance Z in inches, the profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.

6. A compressor comprising a compressor wheel having a plurality of blades, each of said blades cooperating with a plurality of stator vanes, the plurality of stator vanes comprising an airfoil having an uncoated nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A, 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 profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape, the X and Y distances being scalable as a function of the same constant or number to provide at least one of a scaled up vane airfoil and scaled down vane airfoil.

7. A compressor according to claim 6 wherein the plurality of stator vanes comprise a Stage 1 stator vane.

8. A compressor according to claim 6 wherein said airfoil shape lies in an envelope within ±

0.160 inches in a direction normal to any airfoil surface location.
