| 摘 要： | 用热膜测模型表面摩擦应力，在风洞试验中已得到广泛的应用，但在飞行试验中，由于大气温度与地面温度有很大差异，因此传统的校准方法无法应用。本文通过对热膜的传热机理进行分析，找到一种温度修正方法。此方法用于飞行试验中，得到较好的结果。

A STUDY OF TEMPERATURE EFFECT OF HOT FILM SENSORS |

| Abstract: | The measurement of skin friction stress using Hot Film has been used in wind tunnel.But,if want to measure local skin friction stress in flight ,the old calibration method can't be used,because of the difference between the atmosphere temperature and the wind tunnel temperature.This paper find a new temperature correction method through analyzing thermal conduction and convection of Hot Film.The better results are attained by using this method in flight test. |
