Abstract：As the unmanned aerial vehicle(UAV)is a new artificial cloud-seeding operation tech-nological means,studying the anti-icing and deicing of UAV is of great significance for business.Based on the flight ice accumulation report,field observation data,radiosonde and reanalysis data,this article statistically analyzes the meteorological conditions for the distribution of large UAV ice accumulation in Qilian Mountains.Combined with the electric heating anti-ice deicing test,a technical route for UAV an-ti-ice deicing in Qilian Mountains is developed.The results show that the temperature of intense ice accu-mulation area is-8 ℃ to-2 ℃ for the artificial cloud-seeding operation carried out by the large UAV,and ice accumulation is more likely when the cloud particle concentration is greater than 0.93 cm-3 and the cloud water content is greater than 0.0043 g·m-3.In the Qilian Mountains,the height of ice accumu-lation is about 4000-5500 m in spring,autumn and winter,and about 5000-5500 m in summer.The height of ice accumulation center is about 5000 m.The electric heating anti-ice deicing system can effec-tively solve the ice accumulation problem of large UAVs.
