  • Method for manufacturing an airfoil
    Patent number: 9415468
    Abstract: A method for manufacturing an airfoil includes confining an unfocused laser beam inside a first fluid column to create a confined laser beam, directing the confined laser beam at a surface of the airfoil, and penetrating the surface of the airfoil with the confined laser beam. The method further includes detecting penetration of the confined laser beam through the surface of the airfoil via an optical sensor disposed within a cavity defined within the airfoil.
    Type: Grant

  • SYSTEM AND METHOD FOR MANUFACTURING AN AIRFOIL
    Publication number: 20150052751
    Abstract: A system for manufacturing an airfoil includes an unfocused laser beam and a first fluid column surrounding the unfocused laser beam to create a confined laser beam directed at the airfoil. A sensor inside the airfoil detects penetration of the confined laser beam through the surface of the airfoil.
