SYSTEMS AND METHODS FOR VANE COOLING |
| 摘要 |
An airfoil is disclosed comprising a distal edge, a proximal edge, a pressure side surface extending between the distal edge and the proximal edge and between a leading edge and a trailing edge, the leading edge forward of the trailing edge, wherein a first cooling hole and a second cooling hole are disposed in the pressure side surface, wherein the first cooling hole is oriented at a first angle relative to the distal edge and the second cooling hole is oriented at a second angle relative to the proximal edge, wherein the first angle and the second angle have bilateral symmetry about a plane, wherein the plane is located at a point at least one of more than or less than the midpoint between the distal edge and proximal edge. |

1. An airfoil comprising:
a distal edge; a proximal edge; a pressure side surface extending between the distal edge and the proximal edge and between a leading edge and a trailing edge, the leading edge forward of the trailing edge; wherein a first cooling hole and a second cooling hole are disposed in the pressure side surface, wherein the first cooling hole is oriented at a first angle relative to the distal edge and the second cooling hole is oriented at a second angle relative to the proximal edge, wherein the first angle and the second angle have bilateral symmetry about a plane, wherein the plane is located at a point at least one of more than or less than the midpoint between the distal edge and proximal edge. |
