Abstract: A thermal inspection method is disclosed. The inspection method includes disposing a component in a wind tunnel configured to create a predetermined Mach number distribution for an external surface of the component. A gas is supplied at a known temperature T into the wind tunnel to create an external flow of gas over the external surface of the component in accordance with the predetermined Mach number distribution. The inspection method further includes directly or indirectly measuring one or more external surface temperatures of the component to generate an external surface temperature distribution for the external surface of the component and using the external surface temperature distribution to perform a quality control inspection of the component. A thermal inspection system is also provided.

Abstract: A thermal inspection method is provided. The method includes measuring a transient thermal response of a cooled part installed in a turbine engine, wherein the transient thermal response results from operation of the turbine engine. The method also includes using the transient thermal response to determine one or more of a flow rate of a fluid flowing through one or more film cooling holes in the cooled part during operation of the turbine engine, at least one heat transfer coefficient for one or more internal passages in the cooled part, and a combined thermal response for the cooled part. The method further includes comparing at least one of the flow rate, the at least one heat transfer coefficient, and the combined thermal response of at least a portion of the cooled part to at least one baseline value to determine whether a thermal performance of the cooled part is satisfactory.

Abstract: 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.
