摘要： PROBLEM TO BE SOLVED: To develop systems of a composite IR inspection and air flow check, capable of inspecting a coated component as a thermal inspection system.
SOLUTION: The thermal inspection system (10) includes a fluid source (12) configured to indirectly or directly supply a warm flow and a cool flow to internal passages of a component. The system includes an imager (16) configured to capture a time series of images corresponding to a transient thermal response of the component to the warm and cool flows. The system further includes at least one flow meter (24) configured to measure the warm and cool flows supplied to the component, and a processor (22) operably connected to the imager. The processor determines the transient thermal response of the component around a transition time. The flow supplied to the component switches from the warm flow to the cool flow at the transition time. The processor compares the transient thermal response around the transition time with one or more basic values or with an acceptable range of values to determine if the component meets a desired specification.
