TURBINE AIRFOIL |
| 摘要 |
A turbine airfoil includes a leading edge, a trailing edge, a root and a tip. Also included is a pressure side wall extending between the leading edge and the trailing edge and between the root and the tip. Further included is a suction side wall extending between the leading edge and the trailing edge and between the root and the tip. Yet further included is a non-circular cooling channel defined by the turbine airfoil and extending radially from the root to the tip, the non-circular cooling channel routing a cooling air to an outlet hole formed in the tip. Also included is an exhaust hole defined by the turbine airfoil and extending from the non-circular cooling channel to the suction side wall, the exhaust hole radially located between the root and the tip. |

1. A turbine airfoil comprising:
a leading edge; a trailing edge; a root; a tip; a pressure side wall extending between the leading edge and the trailing edge and between the root and the tip; a suction side wall extending between the leading edge and the trailing edge and between the root and the tip; a non-circular cooling channel defined by the turbine airfoil and extending radially from the root to the tip, the non-circular cooling channel routing a cooling air to an outlet hole formed in the tip; and an exhaust hole defined by the turbine airfoil and extending from the non-circular cooling channel to the suction side wall, the exhaust hole radially located between the root and the tip. |
