多旋翼无人飞行器螺旋桨雷诺数的变化范围在104-105左右,属于低雷诺数范围,桨叶的气动性能由翼型决定,雷诺数的大小对翼型性能有着重要影响。基于动量叶素理论,考虑粘性作用,对理论公式进行修正,利用MATLAB、XFOIL软件编制程序并进行计算与分析。
Multi-rotor UAV propeller Reynolds number range of about 104-105, belonging to the low Reynolds number range, the aerodynamic performance of the blade is determined by the airfoil, Reynolds number of the size of the airfoil has an important impact on performance. Based on the momentum valerian theory, considering the viscous effect, the theoretical formula is modified, and the program is programmed and analyzed by using MATLAB and XFOIL software.
