Abstract
The dragonfly has high flight capability in spite of very small size. Therefore, the flight characteristic of dragonfly has been investigated by many researchers. On the wing of dragonfly, there are micro structures have excellent flying abilities . In this study focus on micro structure of wing surface and micro structure of leading edge. These two micro structures are artificially reproduced. The wing with different combination of two micro structures and the wing with no structure are reproduced as text wings. The air characteristic of these micro structures experimentally are verified with using test wings. Drag measurement results showed decrease of drag value in the test wing with microstructures.
