Abstract
A vane includes a pair of airfoils that have a plurality of film cooling holes that extend through an exterior surface of the airfoils. Each plurality of film cooling holes break through the exterior surface at geometric coordinates in accordance with Cartesian coordinate values of X, Y and Z as set forth in Table 1. Each geometric coordinates is measured from a reference point on a leading edge rail of a platform of the vane.
Claims8
A vane comprising:
- a pair of airfoils having a plurality of film cooling holes that extend through an exterior surface of said airfoils, wherein each of said plurality of film cooling holes break through said exterior surface at geometric coordinates in accordance with Cartesian coordinate values of X, Y and Z as set forth in Table 1, wherein each of said geometric coordinates is measured from a reference point on a leading edge rail of a platform of the vane;
- and wherein said Cartesian coordinate values of Table 1 are expressed in inches.
A vane comprising:
- a pair of airfoils extending between inner and outer platforms, the inner and outer platforms include a plurality of film cooling holes that extend through an exterior surface of said platforms, wherein each of said plurality of film cooling holes break through said exterior surface at geometric coordinates in accordance with Cartesian coordinate values of X, Y and Z as set forth in Table 2, wherein each of said geometric coordinates is measured from a reference point on a leading edge rail of a platform of the vane;
- and wherein said Cartesian coordinate values of Table 2 are expressed in inches.
