Patent abstract
A method of replacing an individual damaged compressor stator airfoil includes machining an oversized slot through the stator casing, removing the damaged airfoil, and joining a sleeve to the replacement airfoil and stator casing. The oversized slot creates sufficient clearance for removal of a three-dimensional airfoil, while the sleeve creates a sufficiently tight fit to allow the pieces to be brazed together.
