| 摘 要： | 实现了一种可用于低雷诺数小型折叠无人机翼型优化设计的方法。采用Ferguson曲线对翼型进行参数化描述，并引入折叠状态下截面的几何关系作为附加约束，使用遗传算法和序列二次规划相结合作为寻优算法，对翼型升阻比和折叠空间允许的最大弦长进行优化。在isight平台上集成xFoil和matlab实现了这一优化流程。实例表明了方法的有效性，优化结果可以作为此类无人机翼型设计的参考。

| Abstract: | This paper presents an optimization design method for low Reynolds number foldable UAV airfoil. Ferguson curve was used to describe the parametric airfoil,the geometric relationships in folding state were inducted as additional constrains, the combination of genetic algorithm and sequential quadratic programming was used as seeking optimization algorithm, the liftdrag ratio of airfoil and available chord of wing in folding state were objective functions. The optimization process was realized on platform iSight by integrating software xFoil and matlab. Practical example shows the efficiency of this optimization process, and the result can be used as reference for foldable UAV airfoil design. |
