An important role that the leading-edge cross-section shape plays in the wing flight performance is well known in aeronautics. However, little is known about the shape of the leading-edge cross section of an insect's wing and its contribution to remarkable qualities of insect flight. In this paper, we reveal, in the first time, the shape of the leading-edge cross section of a cicada's wing and analyze its variability along the wing. We also identify and quantify similarities in characteristic dimensions of this shape in the wings of three different cicada species.
前沿横截面形状在机翼飞行性能中所起的重要作用在航空领域是众所周知的。然而，对于昆虫翅膀前沿横截面的形状及其对昆虫飞行卓越特性的贡献却知之甚少。在本文中，我们首次揭示了蝉翼前沿横截面的形状，并分析了其沿翅膀方向的变化情况。我们还识别并量化了三种不同蝉类翅膀中这种形状特征尺寸的相似性。
