  • Method of repairing a stationary airfoil array directing three-dimensional flow
    Patent number: 7761990
    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.
    Type: Grant
