摘要： A thermal inspection system includes a fluid source configured to supply a warm flow and a cool flow, indirectly or directly, to internal passage(s) of a component. The system includes an imager 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 configured to measure the warm and cool flows supplied to the component and a processor 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 baseline values or with an acceptable range of values to determine if the component meets a desired specification.
