Abstract：To address the technical issues such as weak carrying capacity and small downwash flow field existing in current agricultural unmanned aerial vehicle,a coaxial dual-rotor system is introduced to enhance operational efficiency and pesticide application quality.The research focused on the aerodynamic principles of this system,using computational fluid dynamics(CFD)methods to numerically simulate and analyze the downwash flow field of the rotors,and exploring the flow field structure and droplet movement characteristics.The results show that the coaxial dual-rotor design can significantly enhance the downwash airflow,improve the penetration power and uniformity of pesticide spraying,and effectively enhance the carrying capacity.The optimal operating height determined through parameter optimization is 1.5 m.The proposed scheme has the characteristics of high efficiency,precision,and strong adaptability,and can provide technical references for modern agricultural pest control operations.
