TURBINE BLADE |
| 摘要 |
A turbine blade includes an airfoil having an internal cooling circuit. The cooling circuit includes a body cooling passage with at least one turn, and a tip cooling channel that forms a cooling barrier to thermally isolate the turn from at least a portion of the exterior surface of the airfoil. |

1. A turbine blade comprising:
an airfoil extending between a root and a tip, and having a pressure sidewall and a suction sidewall joined together to define a leading edge and a trailing edge; a body cooling passage located within the airfoil and having at least one tip turn located proximate the tip; and a tip cooling channel extending along the tip and enveloping the at least one tip turn to form a cooling barrier between the at least one tip turn and an exterior surface of the airfoil on all sides of the at least one tip turn. |
