Some Coleoptera (popularly referred to as beetles) can fly at a low Reynolds number with their deployable hind wings, which directly enables a low body weight–a good bioinspiration strategy for miniaturization of micro-air vehicles (MAVs). The hind wing is a significant part of the body and has a folding/unfolding mechanism whose unique function benefits from different structures and materials. This review summarizes the actions, factors, and mechanisms of beetle flight and bioinspired MAVs with deployable wings. The elytron controlled by muscles is the protected part for the folded hind wing and influences flight performance. The resilin, the storage material for elasticity, is located in the folding parts. The hind wings’ folding/unfolding mechanism and flight performance can be influenced by vein structures of hollow, solid and wrinkled veins, the hemolymph that flows in hollow veins and its hydraulic mechanism, and various mechanical properties of veins. The action of beetle flight includes flapping flight, hovering, gliding, and landing. The hind wing is passively deformed through force and hemolymph, and the attack angle of the hind wing and the nanomechanics of the veins, muscles and mass body determine the flight performance. Based these factors, bioinspired MAVs with a new deployable wing structure and new materials will be designed to be much more effective and miniaturized. The new fuels and energy supply are significant aspects of MAVs.

一些鞘翅目（通常被称为甲虫）可以通过其可展开的后翼以较低的雷诺数飞行，这直接可以实现低体重-这是微型航空器（MAV）小型化的良好生物启发策略。后翼是人体的重要部分，并具有折叠/展开机构，其独特的功能得益于不同的结构和材料。这篇综述总结了甲壳虫飞行和具有可展开翅膀的生物启发的MAV的作用，因素和机制。受肌肉控制的电子加速器是后折翼的受保护部分，并影响飞行性能。弹性蛋白resilin是用于存储弹性的材料，位于折叠部分中。后翼的折叠/展开机制和飞行性能会受到空心，实心和起皱的静脉的静脉结构的影响，在空心静脉中流动的血淋巴及其液压机制以及静脉的各种机械特性。甲虫飞行的动作包括拍打飞行，悬停，滑行和着陆。后翼通过力和血淋巴而被动变形，后翼的迎角和静脉，肌肉和质体的纳米力学决定了飞行性能。基于这些因素，具有新的可展开机翼结构和新材料的生物启发式MAV将被设计为更加有效和小型化。新燃料和能源供应是MAV的重要方面。后翼通过力和血淋巴而被动变形，后翼的迎角和静脉，肌肉和质体的纳米力学决定了飞行性能。基于这些因素，具有新的可展开机翼结构和新材料的生物启发式MAV将被设计为更加有效和小型化。新燃料和能源供应是MAV的重要方面。后翼通过力和血淋巴而被动变形，后翼的迎角和静脉，肌肉和质体的纳米力学决定了飞行性能。基于这些因素，具有新的可展开机翼结构和新材料的生物启发式MAV将被设计为更加有效和小型化。新燃料和能源供应是MAV的重要方面。
