摘要： A method for repairing an airfoil is provided that includes the steps of: (a) determining repair regions of the airfoil that are likely to be damaged during a period of operation; (b) creating a stress profile for the airfoil that considers dynamic, steady-state, and residual stresses; (c) selecting a replacement section patch line using the stress profile and the determination of those regions likely to be damaged during operation; (d) providing an airfoil replacement section with a predetermined shape having a bond surface that substantially mates with the patch line; (e) removing a portion of the airfoil up to the patch line; (f) bonding the airfoil replacement section to the airfoil along the patch line; and (g) shaping the patched airfoil.

摘要： A method is disclosed for repairing damage to an airfoil. The method provides for the removal of a section of the airfoil that substantially encompasses the damaged area, which consequently leaves a void and a cut-away surface in the airfoil. A replacement piece larger than the residual void is provided for use in replacing the section removed from the airfoil. A joining operation welds or otherwise joins the replacement piece to the airfoil at the cut-away surface to form a joined airfoil. The joined airfoil has a seam between the airfoil and the replacement piece. At least a portion of the seam is processed by laser shock peening to induce compressive residual stresses therein.
