ABSTRACT:
A turbine blade closure system composed of a closure member capable of being friction welded in an aperture in a hollow-cast turbine blade to prevent the escape of cooling fluids from an internal cavity in the turbine blade. In one embodiment, the aperture is formed in the turbine blade during the manufacturing process as a result of one or more support projections used to position a core block in a turbine blade mold.
