The flight of a butterfly is a complex phenomenon in which the flow of air formed by the swing of the wings and the movement of the butterflies themselves are intricately intertwined. Many elements of butterfly aerodynamics still need to be understood, even in terms of basic motion.
A team led by Professor Kasuke Suzuki of Xinxhu University School of Engineering measured the actual movement butterflies with high-speed video and place it in a motion capture program that identifies distinctive points on their wings and body.
The numerical model of the butterfly on the basis of these data was conceived as accurately as possible. Coincidentally, the model reproduced what was suggested by simulation using a simple model that the lab had formulated earlier. Butterfly modelwhich is more accurate than previous research, confirmed what has been suggested in the past.
Now that the group has figured out the lion’s share of how butterflies generate power, the group would like to figure out the mechanism by which a butterfly controls torque without losing its attitude. Ultimately, this mechanism can be applied in the design of micro-air vehicles (MAVs).
