基于热传导反问题结构表面温度辨识

Structure surface temperature identification based on inverse heat conduction problem

结构表面温度是飞机热试验的重要参数。将热传导反问题技术引入飞行试验辨识结构表面温度,建立了飞机薄壁结构换热模型,提出了温度辨识算法,并进行了飞行实测验证。结果表明,该方法具有一定的工程应用价值。

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 thinwall 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.
