Abstract: SPLIT VANE REPAIR A method of repairing a vane cluster for a gas turbine engine includes attaching a first registration block to a salvageable airfoil segment of the vane cluster, machining a face of the first registration block relative to datum surfaces of the vane cluster, removing a damaged airfoil segment from the vane cluster, adding new material to the salvageable airfoil segment, joining a replacement airfoil segment having a second registration block to the salvageable airfoil segment to replace the damaged airfoil segment, removing the first registration block, and removing the second registration block. The respective first and second registration blocks of the salvageable airfoil segment and the replacement airfoil segment are aligned in a configuration substantially identical to a configuration of the vane cluster prior to undergoing repair.

Abstract: A method for working an airfoil cluster is disclosed. The method may include attaching a first datum to a first portion of the airfoil cluster and a second datum to a second portion of the airfoil cluster; adding material to at least one of the first portion and the second portion; and joining the first portion to the second portion, the first and second datums substantially aligned in a common plane spaced away from the first and second portions.

Abstract: 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.
