Small insects with flapping wings, such as bees and flies, have flexible wings with veins, and their compliant motion enhances flight efficiency and robustness. This study investigated the effects of integrating wing veins into soft wings for micro-flapping aerial vehicles. Prototypes of soft wings, featuring various wing areas and vein patterns in both the wing-chord and wing-span directions, were fabricated and evaluated to determine the force generated through flapping. The results indicated that the force is not solely dependent upon the wing area and is influenced by the wing vein pattern. Wings incorporating wing-chord veins produced more force compared to those with wing-span veins. In contrast, when the wing area was the specific wing area, wings with crossed wing veins, comprising both wing-span veins and wing-chord veins, produced more force. Although wing-chord veins tended to exert more influence on the force generated than the wing-span veins, the findings suggested that a combination of wing-span and wing-chord veins may be requisite, depending upon the wing area.
蜜蜂和苍蝇等翅膀能扇动的小昆虫，其翅膀带有脉纹且具有柔韧性，它们顺应性的运动提高了飞行效率和稳健性。本研究调查了将翅脉整合到微型扑翼飞行器的柔性翅膀中的效果。制作了具有不同翼面积以及在翼弦和翼展方向上具有不同脉纹图案的柔性翅膀原型，并对其进行评估以确定扑翼产生的力。结果表明，力并非仅取决于翼面积，还受翅脉图案影响。与具有翼展脉纹的翅膀相比，带有翼弦脉纹的翅膀产生的力更大。相比之下，当翼面积为特定翼面积时，兼具翼展脉纹和翼弦脉纹的交叉翅脉翅膀产生的力更大。尽管翼弦脉纹对产生的力的影响往往比翼展脉纹更大，但研究结果表明，根据翼面积的不同，可能需要同时具备翼展脉纹和翼弦脉纹。
