摘要:

从鉴赏描写蜻蜓的古代诗词入手,介绍了蜻蜓这种经过亿万年进化昆虫的神奇流体力学特性。重点介绍了蜻蜓的复眼、蜻蜓翅膀消除振颤、蜻蜓表皮的超疏水与鳞片减阻、蜻蜓幼虫的喷水推进等力学特性及其对工程技术发展的重要启示,同时介绍了蜻蜓机器人的发展现状。

关键词: 蜻蜓, 复眼, 机翼振颤, 超疏水, 蜻蜓机器人

Abstract:

In the appreciation of the ancient poem for dragonflies, we discuss the magical hydrodynamic characteristics of dragonflies, which have evolved for hundreds of millions of years. The dragonfly's compound eye, the wings' ability of eliminating chatter, the superhydrophobicity of its epidermis, the drag reduction by its scales, and the mechanical characteristics of the water-jet propulsion of the dragonfly larvae; and their inspiration to the development of engineering technology are discussed. At the same time, the development status of the dragonfly robots is introduced as well.

Key words: dragonfly, compound eye, wing flutter, superhydrophobic, dragonfly robot
