Compressor stator chord restoration repair method and apparatus

摘要

A method for defining an airfoil with a radiused shape edge includes joining a filler material to the airfoil such that the filler material defines excess material that extends beyond an operational condition edge location of the edge of the airfoil, placing the airfoil within a barrel, providing an abrasive finishing media in the barrel with the airfoil, rotating the barrel to produce relative motion between the abrasive finishing media and the airfoil. Contact between the abrasive finishing material and the airfoil facilitates removing the excess material that extended beyond the operational condition edge location of the edge of the airfoil.

1. A method for defining an airfoil with a radiused shape edge, the method comprising:
joining a filler material to the airfoil, wherein the filler material defines excess material that extends beyond an operational condition edge location of the edge of the airfoil, wherein the operational condition edge location comprises at least one of an original blueprint edge location and engine manual serviceable limit edge location; performing a cold working process on the filler material joined to the airfoil; after the cold working process, machining a portion of the filler material such that remaining excess filler material extends beyond the operational condition edge location of the airfoil to a planar face; securing the airfoil within a barrel; providing an abrasive finishing media in the barrel with the airfoil; and rotating the barrel to produce relative motion between the abrasive finishing media and the airfoil, wherein contact between the abrasive finishing material and the airfoil removes the excess material that extended beyond the operational condition edge location of the edge of the airfoil to the planar face to produce the radiused shape edge.
