| Outline of Final Research Achievements |
I investigated the mechanism of the flapping flight of butterflies by the simulations using a simple butterfly-like flapping wing-body model in order to apply the numerical results to the development of micro air vehicles. At first, I investigated the effects of the fundamental wing factors of the wings, such as wing shape, wing mass, and wing flexibility, on the flight performance of the model. In addition, I attempted to enhance the lift and thrust forces and to control the attitude of the model by changing the wing kinematics. As a result, I found that appropriate wing factors and kinematics give enough lift force to support the mass of an actual butterfly and enough thrust force to achieve the cruising speed of an actual butterfly even for a simple model, and that the model can control its attitude.

研究期間内に実施した研究はいずれも，蝶の飛翔メカニズムを解明するための基礎的な研究であり，実際のモノ（超小型飛翔体）への応用はまだできていない．しかしながら，本研究を通して，蝶の飛翔メカニズムに関して多くのことが明らかになるとともに，蝶の飛行性能を超えるデザインも可能であることが示唆されている．これらの知見を用いて超小型飛翔体を設計できれば，今までにない小型・軽量でかつ俊敏なドローンが開発できると期待される．
