非致命电击武器是非致命武器领域的研究热点，近年来对无线远程电击子弹的研究是热点问题中的重点，因此针对非致命远程低速电击子弹尾翼设计，选取了Clark Y、Eppler 387、NACA-66共3种在低速有较好气动特性的翼型，使用CFD软件用NACA0012翼型在30 m/s下的仿真结果与文献仿真结果和风洞试验结果对比，验证了算法的有效性，然后对3种翼型低速的气动特性进行仿真，分别得到了在30、35、40 m/s飞行速度下对应不同迎角的升力系数、阻力系数和升阻比。结果表明在同一飞行速度下，3种翼型的升力系数和阻力系数都随攻角的增加逐渐增大，但升力系数的增长幅度逐渐变小，阻力系数的增长幅度逐渐变大，升阻比随攻角的增加先增大后减小，经过对比发现翼型Eppler 387的气动性能优于另外两种翼型，速度为40 m/s、攻角4°~6°为最佳工况，既能满足非致命远程低速电击子弹的结构设计的要求，又能在提供尽可能大滚转力矩的同时产生较小的阻力。

The non-lethal electric shock weapon is a research hotspot in the field of non-lethal weapons. In recent years, the research on wireless long-range electric shock bullets has become a key issue within this field. Therefore, aiming at the design of non-lethal long-range low-velocity electric shock bullet empennage, three airfoils of Clark Y, Eppler 387 and NACA-66 with good aerodynamic characteristics at low velocity were selected. The simulation results of NACA0012 airfoil at 30 m/s using CFD software were compared with the literature simulation results and wind tunnel test results to verify the algorithm's effectiveness. Subsequently, the aerodynamic characteristics of the three airfoils at low velocity were simulated, and the lift coefficient, drag coefficient and lift-drag ratio corresponding to different angles of attack at 30, 35 and 40 m/s were obtained respectively. The results show that at the same flight velocity, the lift coefficient and drag coefficient of the three airfoils gradually increase with the increase of the angle of attack, but the growth rate of the lift coefficient gradually decreases, and the growth rate of the drag coefficient gradually increases. The lift-to-drag ratio increases first and then decreases with the increase of the angle of attack. After comparison, it is found that the aerodynamic performance of the airfoil Eppler 387 is better than that of the other two airfoils. The velocity of 40 m/s and the angle of attack between 4° and 6° are the best working conditions, which can not only meet the structural design requirements of non-lethal long-range low-velocity electric shock bullets, but also produce less drag while providing as much rolling moment as possible.
