| Outline of Final Research Achievements |
Flight performance and stability of insects’ flight in atmospheric turbulence were studied with a mechanical flapper and active turbulence generator. The results showed that the flight with flapping wings is more stable than that of the other flight systems such as rotational wings and fixed airfoils. Moreover, it was found formation flight of small insects is very stable in turbulence flow fields. This is because flapping wings generate large separated flow, it is not influenced the formation flight and incoming turbulence. It is very stable against disturbances. This is significantly different from the flight utilizing a lift forces such as airplanes. For small insects such as a dragonfly, the benefit of formation flights is small, it is important to be able to fly alone in turbulence flow fields.
