  • Thermographic detection of internal passageway blockages
    Patent number: 8287183
    Abstract: A method of thermal inspection of a component defining at least one internal passageway. The method includes receiving a continuous sequence of thermal images of at least an exit hole defined by the at least one internal passageway at a surface of the component. The method also includes delivering a pressurized airflow pulse into the at least one internal passageway, receiving a temperature response signal as function of time based on the received thermal images, determining a first derivative of the temperature response signal, and determining a level of blockage of the at least one internal passageway based on the first derivative of the temperature response signal.
    Type: Grant
