Abstract

An article of manufacture having a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a scalable table, the scalable table selected from the group of tables consisting of TABLES 1-11, wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete airfoil shape.

Claims (22)

1. An article of manufacture having a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a scalable table, the scalable table selected from the group of tables consisting of TABLES 1-11, wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete airfoil shape.

2. The article of manufacture according to claim 1 , wherein the article of manufacture comprises a rotor blade configured for use with a compressor.

3. The article of manufacture according to claim 1 , wherein the airfoil shape lies in an envelope within:

+/−5% of a chord length in a direction normal to an airfoil surface location.

4. The article of manufacture according to claim 1 , wherein the number, used to convert the non-dimensional values to dimensional distances, is one of a fraction, decimal fraction, integer and mixed number.

5. The article of manufacture according to claim 1 , wherein a height of the article of manufacture is about 1 inch to about 20 inches.

6. An article of manufacture having a suction-side nominal airfoil profile substantially in accordance with suction-side Cartesian coordinate values of X, Y and Z set forth in a scalable table, the scalable table selected from the group of tables consisting of TABLES 1-11, wherein the Cartesian coordinate values of X, Y and Z are nondimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete suction-side airfoil shape, the X, Y and Z coordinate values being scalable as a function of the number to provide one of a non-scaled, scaled-up and scaled-down airfoil profile.

7. The article of manufacture according to claim 6 , wherein the article of manufacture comprises a rotor blade configured for use with a compressor.

8. The article of manufacture according to claim 6 , wherein the suction-side airfoil shape lies in an envelope within:

+/−5% of a chord length in a direction normal to a suction-side airfoil surface location.

9. The article of manufacture according to claim 6 , wherein the number, used to convert the non-dimensional values to dimensional distances, is one of a fraction, decimal fraction, integer and mixed number.

10. The article of manufacture according to claim 6 , wherein a height of the article of manufacture is about 1 inch to about 20 inches.

11. The article of manufacture according to claim 6 , further comprising the article of manufacture having a pressure-side nominal airfoil profile substantially in accordance with pressure-side Cartesian coordinate values of X, Y and Z set forth in the scalable table, wherein the Cartesian coordinate values of X, Y and Z are nondimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by the number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete pressure-side airfoil shape, the X, Y and Z values being scalable as a function of the number to provide one of a non-scaled, scaled-up and scaled-down airfoil.

12. A compressor comprising a plurality of rotor blades, each of the rotor blades including an airfoil having a suction-side airfoil shape, the airfoil having a nominal profile substantially in accordance with suction-side Cartesian coordinate values of X, Y and Z set forth in a scalable table, the scalable table selected from the group of tables consisting of TABLES 1-11, wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete suction-side airfoil shape.

13. The compressor according to claim 12 , wherein the suction-side airfoil shape lies in an envelope within:

+/−5% of a chord length in a direction normal to a suction-side airfoil surface location.

14. The compressor according to claim 12 , wherein the number, used to convert the non-dimensional values to dimensional distances, is one of a fraction, decimal fraction, integer and mixed number.

15. The compressor according to claim 12 , wherein a height of each rotor blade is about 1 inch to about 20 inches.

16. The compressor according to claim 12 , further comprising each of the plurality of rotor blades having a pressure-side nominal airfoil profile substantially in accordance with pressure-side Cartesian coordinate values of X, Y and Z set forth in the scalable table, wherein the Cartesian coordinate values of X, Y and Z are nondimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by the number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete pressure-side airfoil shape.

17. The compressor according to claim 16 , wherein the pressure-side airfoil shape lies in an envelope within:

+/−5% of a chord length in a direction normal to a pressure-side airfoil surface location.

18. The compressor according to claim 16 , wherein the number, used to convert the non-dimensional values to dimensional distances, is one of a fraction, decimal fraction, integer and mixed number.
