Abstract
Compressor components, such as blades and vanes, having an airfoil portion with an uncoated, nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in Table 1. X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each Z distance in inches. The profile sections at the Z distances are joined smoothly with one another to form a complete airfoil shape.
Claims17
A compressor component comprising:
- a root portion;
- and
- an airfoil portion extending from the root portion, the airfoil portion having an uncoated nominal profile in accordance with Cartesian coordinate values of X, Y, and Z set forth in Table 1,
- wherein the X, Y, and Z coordinates are distances in inches measured in a Cartesian coordinate system,
- wherein at each Z distance, corresponding X and Y coordinates are connected by a smooth continuous arc to define one of a plurality of airfoil profile sections, and
- wherein the plurality of airfoil profile sections are joined together by smooth continuous arcs to form the airfoil profile.
A compressor blade, comprising:
- an airfoil portion having an uncoated nominal profile in accordance with Cartesian coordinate values of X, Y, and Z set forth in Table 1,
- wherein the X, Y, and Z coordinate values are distances in inches measured in a Cartesian coordinate system,
- wherein at each Z distance, corresponding X and Y coordinates are connected by a smooth continuous arc to define one of a plurality of airfoil profile sections, and
- wherein the plurality of airfoil profile sections are joined together by smooth continuous arcs to define the airfoil profile.
A compressor, comprising:
- a casing;
- a rotor disc positioned within the casing;
- and
- a plurality of compressor blades coupled to the rotor disc, the plurality of compressor blades circumferentially spaced around the rotor disc about a center axis of the compressor, wherein each compressor blade of the plurality of compressor blades has an airfoil comprising:
- an airfoil portion having an uncoated nominal profile in accordance with Cartesian coordinate values of X, Y, and Z set forth in Table 1,
- wherein the X, Y, and Z coordinate values are distances in inches measured in a Cartesian coordinate system,
- wherein at each Z distance, corresponding X and Y coordinates are connected by a smooth continuous arc to define one of a plurality of airfoil profile sections, and
- wherein the plurality of airfoil profile sections are joined together by smooth continuous arcs to define the airfoil profile.
