J0202-4-5 Visualization using a Simulator that have Wing Interval same as Dragonfly

Abstract

The purpose of this study is to bring out Dragonfly's aerodynamic characteristics. It is very difficult to know aerodynamic characteristics of the Dragonfly using the conventional observation technology when it is flying freely. Therefore we developed the wing motion simulator which have same wing interval as natural Dragonfly's and we visualized the flow around the wing in flapping motion using it. It is clarified how wing interval influences aerodynamic characteristic of Dragonfly.
