Aerodynamic Simulation Analysis of Tandem Rotor UAV
In order to address the reduced rotor efficiency caused by the aerodynamic interference from the overlapping rotor blades in a tandem coaxial unmanned aerial vehicle(UAV),this study conducted a simulation analysis of the aerodynamic characteristics of the tandem coaxial UAV using computational fluid dynamics(CFD)methods.The analysis included different angles of attack,variations in the relative positions of the two rotor blades,and aerodynamic shape optimization of the fairing.The research results indicate that the angle of attack has a greater influence on the lift coefficient than the drag coefficient at different angles of attack.The interference of the rotor is minimized and the efficiency is maximized when the two rotor blades have a longitudinal distance of 3420 mm and an axial distance of 540 mm.Subsequently,an optimization of the fairing was performed,resulting in a more favorable aerodynamic shape.The findings of this study provide important references and guidance for the aerodynamic design of tandem coaxial UAVs,while also offering valuable practical experience for the development and application of UAVs.
