The aerodynamic characteristics of the Coleopteran beetle species Epilachna quadricollis, a species with flexible hind wings and stiff elytra (fore wings), are investigated in terms of hovering flight. The flapping wing kinematics of the Coleopteran insect are modeled through experimental observations with a digital high-speed camera and curve fitting from an ideal harmonic kinematics model. This model numerically simulates flight by estimating a cross section of the wing as a two-dimensional elliptical plane. There is currently no detailed study on the role of the elytron or how the elytron-hind wing interaction affects aerodynamic performance. In the case of hovering flight, the relatively small vertical or horizontal forces generated by the elytron suggest that the elytron makes no significant contribution to aerodynamic force.
鞘翅目甲虫物种二十八星瓢虫(Epilachna quadricollis)的空气动力学特性,特别是其具有灵活的后翅和坚硬的鞘翅(前翅),在悬停飞行中进行了研究。通过使用数字高速摄像机进行实验观察并从理想的谐波运动学模型进行曲线拟合,对鞘翅目昆虫的扑翼运动学进行了建模。该模型通过将机翼的横截面估计为二维椭圆形平面来数值模拟飞行。目前还没有关于鞘翅的作用或鞘翅与后翅相互作用如何影响空气动力学性能的详细研究。在悬停飞行中,鞘翅产生的相对较小的垂直或水平力表明鞘翅对空气动力没有显著贡献。
