多旋翼无人机旋翼风场分布情况研究

Research on the Distribution of Rotor Wind Field in Multi-rotor UAV

具有较高探测精度是对多旋翼无人机气象探测平台的基本要求,而旋翼风场是影响探测精度的重要方面,因此研究旋翼风场、确定风场影响范围变得尤为必要。论文基于CFD方法,通过标定转速、统一间距比、统一桨叶数目及形状,利用Fluent软件重点对四旋翼及六旋翼无人机旋翼特定转速情况下产生的风场进行研究,为确定风探测设备最佳安装位置提供了依据,并指出了下步的研究重点。

High detection accuracy is a basic requirement for multi-rotor UAV weather detection platform,and rotor wind field is an important aspect that affects detection accuracy.Therefore,it is particularly necessary to study rotor wind field and deter⁃mine the influence range of the wind field.Based on the CFD method,this thesis focuses on the research on the wind field generated by the quad-rotor and the hexa-rotor at specific speeds by calibrating the speed,the uniform pitch ratio,the number and shape of the blades,and the use of fluent software,which provides a basis for determining the best installation location of wind detection equip⁃ment,and points out the next step of the research focus.
