PROBLEM TO BE SOLVED: To provide a system and method for manufacturing an airfoil that enables larger aspect ratios.SOLUTION: A system for manufacturing an airfoil includes an outer surface of the airfoil, a cavity inside the airfoil, and a collimator outside of the airfoil. The system further includes a fluid column flowing from the collimator toward the outer surface of the airfoil, and a laser beam inside the fluid column to create a confined laser beam directed at the outer surface of the airfoil. A method for manufacturing an airfoil includes confining a laser beam inside a fluid column to create a confined laser beam, directing the confined laser beam at an outer surface of the airfoil, and creating a passage through the outer surface of the airfoil with the confined laser beam. |
