Abstract

A turbine vane for a gas turbine engine, including: a first airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from an inner platform in a radial direction to an outer platform, wherein a portion of the exterior airfoil surface of the first airfoil is formed in conformance with a set of Cartesian coordinates set forth in Table 1 as offset by corresponding values in Table 4, and wherein the values of Table 4 are offset from a point of origin that is a point where a radially outward surface of the inner platform meets a surface of a trailing edge of the inner platform and a surface of a mate face of the inner platform.

Claims (28)

1. A turbine vane for a gas turbine engine, comprising:

a first airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from an inner platform in a radial direction to an outer platform, wherein a portion of the exterior airfoil surface of the first airfoil is formed in conformance with a set of Cartesian coordinates set forth in Table 1 as offset by corresponding values in Table 4, and wherein the values of Table 4 are offset from a point of origin that is a point where a radially outward surface of the inner platform meets a surface of a trailing edge of the inner platform and a surface of a mate face of the inner platform, wherein the set of Cartesian coordinates in Table 1 have a tolerance of ±0.020 inches (±0.508 mm).

2. The turbine vane according to claim 1 , wherein the turbine vane is a second stage turbine vane.

3. The turbine vane of claim 1 , wherein the inner platform, the first airfoil and the outer platform are cast as a single part.

4. The turbine vane of claim 1 , wherein other portions of the exterior airfoil surface of the first airfoil are formed in conformance with a set of Cartesian coordinates set forth in Tables 2 and 3 as offset by corresponding values in Table 4.

5. The turbine vane of claim 1 , further comprising:

a second airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from the inner platform in a radial direction to the outer platform.

6. A turbine stator assembly for a gas turbine engine, comprising:

a plurality of turbine vanes secured about an axis, each of the plurality of turbine vanes having:

a first airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from an inner platform in a radial direction to an outer platform, wherein a portion of the exterior airfoil surface of the first airfoil is formed in conformance with a set of Cartesian coordinates set forth in Table 1 as offset by corresponding values in Table 4, and wherein the values of Table 4 are offset from a point of origin that is a point where a radially outward surface of the inner platform meets a surface of a trailing edge of the inner platform and a surface of a mate face of the inner platform, wherein the set of Cartesian coordinates in Table 1 have a tolerance of ±0.020 inches (±0.508 mm).

7. The turbine stator assembly of claim 6 , wherein the turbine stator assembly is a second stage turbine stator assembly of a high pressure turbine of the gas turbine engine.

8. The turbine stator assembly of claim 6 , wherein each of the plurality of turbine vanes further comprises:

a second airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from the inner platform in a radial direction to the outer platform.

9. The turbine stator assembly of claim 8 , wherein the inner platform, the first airfoil, the second airfoil and the outer platform are cast as a single part.

10. The turbine stator assembly of claim 6 , wherein other portions of the exterior airfoil surface of the first airfoil are formed in conformance with a set of Cartesian coordinates set forth in Tables 2 and 3 as offset by corresponding values in Table 4.

11. A gas turbine engine comprising:

a compressor section;

a combustor fluidly connected to the compressor section;

a turbine section fluidly connected to the combustor, the turbine section comprising:

a high pressure turbine coupled to a high pressure compressor of the compressor section via a shaft;

a low pressure turbine; and

wherein the high pressure turbine includes a turbine stator assembly comprising:

a plurality of turbine vanes secured about an axis, each of the plurality of turbine vanes having:

a first airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from an inner platform in a radial direction to an outer platform, wherein a portion of the exterior airfoil surface of the first airfoil is formed in conformance with a set of Cartesian coordinates set forth in Table 1 as offset by corresponding values in Table 4, and wherein the values of Table 4 are offset from a point of origin that is a point where a radially outward surface of the inner platform meets a surface of a trailing edge of the inner platform and a surface of a mate face of the inner platform, wherein the set of Cartesian coordinates in Table 1 have a tolerance of ±0.020 inches (±0.508 mm).

12. The gas turbine engine of claim 11 , wherein the turbine stator assembly is a second stage turbine stator assembly of the gas turbine engine.

13. The gas turbine engine of claim 11 , wherein the inner platform, the first airfoil, and the outer platform are cast as a single part.

14. The gas turbine engine of claim 11 , further comprising:

a second airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending from the inner platform in a radial direction to the outer platform.
