In recent years, attention has been paid to the activity of Unmanned Aerial Vehicle such as disaster site surveys and home delivery using drones. In order to improve the performance of UAV, the application of biomimetics is considered. Dragonflies are the highest flight performance in all organisms. It is thought that various microstructures existing in dragonfly wings are important. In this paper is paid attention to a micro spike of about 100 μm moreover analyzed the numerical fluid using ANSYS FLUENT. As a result, it was confirmed that the flow velocity around the micro spike was reduced. From the above, it is considered that the drag coefficient changes by micro spike.
