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.
