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。 Structural surface temperature is an important parameter for aircraft thermal tests. The heat conduction inverse problem technology is introduced into the flight test to identify the surface temperature of the structure, the heat transfer model of the aircraft thin-walled structure is established, the temperature identification algorithm is proposed, and the flight verification is carried out. The results show that this method has some engineering application value.
