Abstract

See full text

A method of thermal inspection of a component defining at least one internal passageway at a thermal equilibrium state with its surrounding environment, the method includes: capturing a sequence of thermal indications of a surface of the component, delivering an airflow pulse at the thermal equilibrium state of the at least one internal passageway into the at least one internal passageway, and receiving a temperature response signal as a function of time based on the received thermal indication. The method also includes determining a level of blockage of the at least one internal passageway based on the temperature response signal.
