  • Fluorescent inspection of airfoil cooling holes
    Patent number: 7095495
    Abstract: A system and method are provided for inspecting cooling holes of a completed, lasered, and deburred turbine airfoil. The cooling holes are covered with a very porous tape before placing the turbine airfoil into an air fixture that has a metered amount of fluorescent liquid dripped into the airline. The atomized fluorescent liquid flows through the turbine airfoil internal cavities, exiting through the open cooling holes, where it is absorbed by the porous tape. A pattern will appear on the tape surface, in the area of the open holes, indicative of the presence of not-through or plugged cooling holes.
    Type: Grant
