MODELLING AND MANUFACTURING OF A DRAGONFLY WING AS BASIS FOR BIONIC RESEARCH
Working principles in nature have been optimised by evolution for millions of years. Today we try to understand these principles and to utilise them in technical applications. The dragonfly combines very light wing structures with amazing flying abilities by using the effect of rotating vortices. Future airplanes could use this effect to improve their flight dynamics and energy efficiency. In order to study the exact properties of the dragonfly wing and to understand how these properties can be achieved, it is necessary to reproduce the geometry of the wing at a larger scale. In this paper the authors describe the modelling and building of an enlarged model of a dragonfly wing as base for further bionic research.
