In the nearly one-hour flight demonstration event, TDN-01 completed a series of simulated plant protection operations, such as charge, takeoff, spraying, rotation, hovering, and return landing. This is China's first full-scale research and development. The 80-liter drug-loaded agricultural plant protection unmanned helicopter. The drone was independently developed and manufactured by Shenzhen United Aircraft Technology Co., Ltd.

According to Liu Yunling, a professor at the China Agricultural University, “At present, plant protection drones are mainly based on small motors. The drug load does not exceed 10 liters and takes off and take off every 15 minutes. This will seriously affect the efficiency of pesticide spraying. Visible Drug loading is a bottleneck restricting the development of plant protection drones and modern agriculture. However, the TDN-01, the largest drug-loaded plant protection drone in the country, has been introduced. This large-scale agricultural unmanned helicopter developed by the joint aircraft has been loaded with drugs. The volume has reached 80 litres. It is the model with the largest drug load and the longest life time in domestic agricultural drones. Calculated according to 20 minutes per rack, 8 hours of working time per day. Theoretically, it can work 2000 mu per day.

The world's largest plant protection company, Syngenta, has been paying attention to the latest development of agricultural drones. Liu De, director of marketing for Greater China of China, expressed confidence in the future of the TDN-01 model and will take the lead in applying the large-scale TDN-01. Plant protection drone.
