Research on the Influence of UAV Anti-collision Device on Aerodynamic Shape

Abstract With the widespread use of UAVs, accidents with UAVs are inevitable. It is necessary to design an anti-collision UAV suitable for aircraft inspection. CFD simulation software is used to study the effect of adding anti-collision device on the hovering, flow field characteristics and aerodynamic shape of the UAV. The model parameters are set according to the actual situation, and the flow field characteristics of a single propeller, UAV and anti-collision UAV are simulated and analyzed in the hovering state. The analysis of the flow field determines the aerodynamic interference of the UAV anti-collision device, which provides a basis for verifying the feasibility of the design scheme.
