摘　　要：飞机除冰是影响民航冬季安全运行的重要因素之一,为了优化飞机除冰液参数,设计了飞机地面除冰室外实验。在冬季室外条件下通过对结冰的模拟机体表面喷射加热的除冰液进行除冰,在除冰过程中对除冰液流量、除冰液温度进行控制,通过安装在机体上的温度传感器和光纤传感器得到飞机机体表面温度变化和冰层厚度变化情况。通过分析实验结果可得:在一定范围内,除冰液温度升高能有效提高除冰速率;除冰液流量增加也能提高除冰速率,但当除冰液流量超过一定值时,射流冲击成为除冰的主要动力。Aircraft icing is one of the important factors that affect civil aviation safety in operation in winter. In order to optimize parameters of aircraft deicing fluid, aircraft ground deicing outdoor experiment is carried out. In winter outdoor conditions, aircraft deicing is operated by injecting heated deicing fluid to the aircraft surface. The temperature and the velocity of the flow must be changed regularly, and change of temperature and ice thickness can be detected by temperature sensor and fibre-optic sensor that are installed on the aircraft surface. By analyzing result of experiment, the conclusion is that, in certain range the temperature rise of deicing liquid increases apparently ice removal rate, but the jet impact force will be the main force of deicing when the velocity of flow exceeds certain value.
