Moreover, the current state of the bionic study on the functional characteristics of dragonfly wings is analyzed and its application prospect is depicted.

In this paper, the functional characteristics of the dragonfly wings including flying, self-cleaning, anti-fatigue, vibration elimination and noise reduction are introduced and the effects of their morphology, configuration, structure and material on the functional characteristics are described. In resent years, some progresses have been achieved in the researches on the wingsвЂ™ geometric structure, material characteristics, flying mechanism and the controlling mode.

The functional characteristics presented by dragonfly wings provide an biological inspiration for the investigation and development of aerospace vehicles and bionics flapping aerocraft flapping-wing micro air vehicles. Dragonfly is one of the most excellent nature flyers, and its wings exhibit excellent functional characteristics through the coupling and synergy of morphology, configuration, structure and material.
