AIRFOIL SHAPE FOR COMPRESSOR INLET GUIDE VANE
First Claim
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 inlet guide vane airfoil shape.

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 inlet guide vane airfoil shape.

4. A compressor comprising a compressor wheel having a plurality of blades, each of said blades cooperating with a plurality of stator vanes, the compressor comprising an inlet guide vane 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 inlet guide vane airfoil shape.
- 5. A compressor comprising a compressor wheel having a plurality of blades, each of said blades cooperating with a plurality of stator vanes, the compressor comprising an inlet guide vane 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 inlet guide vane 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 inlet guide vane airfoil and scaled down inlet guide vane airfoil.
