摘　　要：为了充分发挥共轴双旋翼的气动性能,减少不必要的功率损耗,基于XFlow软件,对共轴旋翼无人机机翼翼型、攻角及叶片数量进行了仿真分析。在初始设计及初步分析的基础上,通过控制变量来修改和控制旋翼叶片的数量、外形、角度和长度对无人机进行气动优化设计,从而达到一个较为满意的升力。研究结果表明,8-16叶片混合优化方案可以较有效地减少上下旋翼间的相互影响,优化后的模型相比初始模型的升力提高了18.54%,扭矩提高了9.60%,功率提升了17.67%,各项气动特性数值都达到了较为理想的状态,优化效果较为明显。In view of a full utilization of the aerodynamic performance of coaxial twin rotors and a reduction of unnecessary power losses,based on XFlow software,a simulation analysis has thus been conducted on the wing profile,angle of attack,and number of blades of coaxial rotor unmanned aerial vehicles.On the basis of the initial design and analysis,the aerodynamic optimization design of the drone is carried out by controlling variables to modify and control the number,shape,angle,and length of the rotor blades,so as to achieve a satisfactory lift.The research results show that the 8-16 blade hybrid optimization scheme can effectively reduce the mutual influence between the upper and lower rotors.The optimized model has increased lift by 18.54%,torque by 9.60%,and power by 17.67%compared to the initial model.All the aerodynamic characteristics of the optimized model have reached a relatively ideal state,with an more evident optimization effect.
