| Abstract: | Structure surface temperature is an important parameter in aircraft thermal test.The technology of IHCP was brought into flight test to identify structure surface temperature.Heat transfer model for thin-wall structure of aircraft was built.The temperature identification method was proposed based on the model.Flight test data was used to check the method.Results show that the method has engineering application value. |
