Abstract
An apparatus for identifying and clearing blockages in cooling orifices of an airfoil is described. The apparatus includes a processor for controlling the various functions of the apparatus. Light is directed into a cavity of the airfoil and a detector is used for detecting light passing through the orifices. The processor determines blockages of the orifices by comparing detected light pattern with a predetermined pattern. The apparatus further includes a nozzle controlled by the processor for directing pressurized water to open the blocked orifices.
