SPLIT AIRFOIL CLUSTER AND METHOD THEREFOR |
| 摘要 |
A method of fabricating airfoil cluster includes providing an airfoil cluster that has a pair of spaced-apart airfoils that extend from a common platform wall. The airfoil cluster is then divided through the common platform wall to provide separate first and second airfoil segments. At least one cooling hole is then formed in at least one of the first and second airfoil segments. The segments are then metallurgically fused together in a distinct metallurgical joint in the common platform wall. |

1. A method of fabricating an airfoil cluster, the method comprising:
providing an airfoil cluster including a pair of spaced-apart airfoils that extend from a common platform wall; dividing the airfoil cluster through the common platform wall to provide separate first and second airfoil segments; forming at least one cooling hole in at least one of the first and second airfoil segments; and metallurgically fusing the first and second airfoil segments together in a distinct metallurgical joint in the common platform wall. |
