Abstract: A method for repairing one or more holes in a near wall of a component is provided. The method includes determining updated hole information, including an updated location, of a first hole in the near wall of the component. The method also includes directing a confined laser beam of the confined laser drill towards the near wall of the component at the updated location of the first hole to drill through a coating of the component extending over and/or positioned in the first hole. The method also includes sensing a characteristic of light reflected from the updated location of the first hole and determining the confined laser beam of the confined laser drill has drilled through a portion of the coating of the component extending over and/or positioned in the first hole based on the sensed characteristic of light.

Abstract: A system for forming a passage in an airfoil includes a liquid-jet guided laser that generates a laser beam confined within a fluid column, and a purge medium supply that is fluidly coupled to an aperture of the airfoil. A purge medium flows from the purge medium supply in a flow direction that is substantially parallel to an inner surface of the inner cavity. A controller is configured to direct the liquid-jet guided laser to cut a first passage through the outer surface. A centerline of the passage forms an acute angle with respect to the purge medium flow direction. The first passage is formed at a first radial position that is radially distal to the aperture. A method for forming passages in an airfoil using the system described herein is also disclosed.

Abstract: A system for forming a cooling hole in an airfoil includes a liquid-jet guided laser. The liquid-jet guided laser generates a laser beam confined within a fluid column. The fluid column/laser beam is directed at an outer surface of the airfoil. The system also includes a purge medium supply that is fluidly coupled to an aperture of the airfoil. The purge medium supply provides a purge medium into an inner cavity of the airfoil. The purge medium flow is oriented to flow in a flow direction that is substantially parallel to an inner surface of the cavity. A cooling hole is formed in the airfoil and extends through the outer surface and penetrates the inner surface of the cavity. A centerline of the cooling hole forms an acute angle with respect to the purge medium flow direction. The system described herein provides a method for manufacturing an airfoil.

Abstract: This disclosure provides a shield for use in a liquid guided laser system and related method of use. The shield comprises a rigid body with a target facing surface. The rigid body defines a through hole with a diameter that accommodates a liquid guided laser path. The rigid body has a thickness that defines a length of the liquid guided laser path through the rigid body. The thickness of the rigid body is at least twice the diameter of the through hole. The rigid body is positioned in the liquid guided laser path of the liquid guided laser system between a discharge nozzle of the liquid guided laser system and a target.
