摘要:
针对四旋翼无人机噪声控制与气动效能提升的双重需求,基于猫头鹰羽翼的形态特征,提取前缘锯齿结构、后缘梳状结构和下表面阵列结构,开展四旋翼无人机旋翼耦合仿生研究。应用Fluent软件进行参数化CFD仿真,研究旋翼在悬停工况下不同转速的噪声和升力,仿真结果表明,下表面阵列结构和后缘梳状结构均能改善旋翼的降噪性能和气动性能。将下表面阵列结构分别与后缘梳状和前缘锯齿结构耦合,其性能可进一步改善,且实验结果表明,下表面阵列结构与后缘梳状结构耦合性能最佳,相对于原型旋翼升力提升了约18.6 %,噪声最大降低4.5 dB。该研究结果可为四旋翼无人机旋翼结构设计提供理论参考。
Abstract:
 To address the dual requirements of noise control and aerodynamic efficiency enhancement for quadrotor Unmanned Aerial Vehicles (UAVs),the study of bionic coupling for quadrotor rotors is conducted based on the morphological characteristics of owl feathers.Key features including the serrated leading edge structure,fringed trailing edge structure,and ventral array structure are extracted.Parametric Computational Fluid Dynamics (CFD) simulations using Fluent software are performed to investigate the noise and lift performance of the rotors under hovering conditions with different rotational speeds.The simulation results indicate that both the ventral array structure and the fringed trailing edge structure can improve the noise reduction and aerodynamic performance of the rotor.Coupling the ventral array structure with the fringed trailing edge structure and the serrated leading edge structure,respectively,leads to further performance enhancements.Experimental results demonstrate that the coupling of the ventral array structure and the fringed trailing edge structure yields the optimal performance,achieving approximately an 18.6 % increase in lift and a maximum noise reduction of 4.5 dB compared to the prototype rotor.These findings can provide theoretical reference for the structural design of quadrotor UAV rotors.
