    Abstract: CURVED VARIABLE PITCH WEDGE RETENTION IN VANE OUTER BASE 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.

    Abstract: A method for filling cooling holes in a component of a gas turbine engine is disclosed. The component may include a plurality of first cooling holes extending through the wall of the component. The method may comprise the steps of exposing the outer surface of the component, filling the plurality of first cooling holes with a polyimide, curing the polyimide to block the passage of cooling fluid through the plurality of first cooling holes, and applying a thermal bather coating over the outer surface of the component. The method may further include the step of installing a second plurality of cooling holes in the wall of the component wherein the plurality of second cooling holes penetrate the thermal barrier coating and the wall of the component and allow cooling fluid to pass therethrough.

    Abstract: A method for repairing or replacing a mechanically retained vane is provided. The method comprises the steps of forming an oversized cavity (50) in an outer base (52), inserting a flared end (18) of a vane in the oversized cavity (50), and inserting a wedge (70) for mechanically retaining the flared end (18) of the vane in the oversized cavity (50). The wedge (70) has a first surface (72) with a constant pitch angle to match the outer base cavity (50) and a second surface (74) with a variable pitch angle to match the vane tip dovetail.
