Abstract

The efficiency of the precision spraying application employing Unmanned Aircraft Systems (UAS) is significantly influenced by disturbances that impact the system, consequently affecting trajectory accuracy. For this purpose, a hexagonal tank with a capacity of 10 L, featuring two perforated plates, has emerged as the most optimal solution for UAS with an MTOW of 25 kg, aimed at minimizing the adverse effect of liquid sloshing. Computational Fluid Dynamics (CFD) analysis is conducted using SolidWorks Flow Simulation software. In order to identify the forces and moments acting inside the tank and their impact on UAS dynamics, a simulated scenario involving a sudden change in flight path is employed. The results show that the introduction of perforated plates, combined with the control system's work, effectively mitigates fluid motion, leading to improvements in trajectory tracking, spray performance, and overall safety.
