Abstract:
A method for repairing or replacing a mechanically retained vane is provided. The method comprises the steps of forming an oversized cavity in an outer base, inserting a flared end of a vane in the oversized cavity, and inserting a wedge for mechanically retaining the flared end of the vane in the oversized cavity. The wedge has a first surface with a constant pitch angle to match the outer base cavity and a second surface with a variable pitch angle to match the vane tip dovetail.
