Flighted beetles have deployable hindwings, which enable them to directly reduce their body size, and thus are excellent bioinspired prototypes for microair vehicles (MAVs). The wing shape of MAVs has an important influence on their aerodynamics. In this paper, wing shapes, inspired from three beetle species' hindwings and designed in terms of the wing camber angle, geometry (including wing length, aspect ratio (AR), and taper ratio (TR)) and wing area, were selected and varied to optimize lift together with the efficiency of wing. All the wings were fabricated by a Tyvek membrane and tested in a wind tunnel. The camber angle and AR were found to have a critical role in force production. The best performance was obtained by a wing with a camber angle of 10°, wing length of 125 mm, AR of 7.06, TR of 0.40 and wing area of 4115 mm.
有翅甲虫具有可展开的后翅，这使它们能够直接减小身体尺寸，因此是微飞行器 (MAV) 的极佳仿生原型。MAV 的机翼形状对其空气动力学性能有重要影响。在本文中，从三种甲虫的后翅获得的机翼形状，根据翼型弯度角、几何形状（包括翼展长、展弦比 (AR) 和锥比 (TR)）和机翼面积进行了选择和变化，以优化升力和机翼效率。所有机翼均由 Tyvek 膜制成，并在风洞中进行了测试。结果发现，弯度角和 AR 对力的产生起着关键作用。通过具有 10°弯度角、125 毫米翼展长、7.06 的展弦比、0.40 的锥比和 4115 毫米机翼面积的机翼，获得了最佳性能。
