Abstract

An article of manufacture having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a table. The table selected from the group of tables consisting of TABLES 1S–16S, 1R–17R, and IGV. 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.

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 a table, the table selected from the group of tables consisting of TABLES 1S–

16S, 1R–

17R, and IGV, 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 article comprises an airfoil.

3. An article of manufacture according to claim 2, wherein said article 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 article comprises a rotor.

5. An article of manufacture according to claim 1, wherein the article comprises a stator.

6. An article of manufacture according to claim 1, wherein the article comprises an inlet guide vane.

7. A compressor comprising a compressor wheel having a plurality of articles of manufacture, each of said articles of manufacture including an airfoil having an airfoil shape, said airfoil having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a table, the table selected from the group of tables consisting of TABLES 1S–

16S, 1R–

17R, and IGV, 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.

8. A compressor according to claim 7, wherein the article of manufacture article comprises a rotor.

9. A compressor according to claim 7, wherein the article of manufacture comprises a stator.

10. A compressor according to claim 7, wherein the article of manufacture comprises an inlet guide vane.

11. A compressor comprising a compressor wheel having a plurality of articles of manufacture, each of said articles of manufacture including an airfoil having an uncoated nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a table, the table selected from the group of tables consisting of TABLES 1S–

16S, 1R–

17R, and IGV, 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 a scaled-up or scaled-down rotor blade airfoil.

12. A compressor according to claim 11, wherein the article of manufacture article comprises a rotor.

13. A compressor according to claim 11, wherein the article of manufacture comprises a stator.

14. A compressor according to claim 11, wherein the article of manufacture comprises an inlet guide vane.

15. A compressor according to claim 11 wherein said airfoil shape lies in an envelope within ±

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