219 トンボを対象としたシミュレーションロボットの開発(第1報)(S38-1 小型飛翔体(1),S38 生物飛行と小型飛翔体)  [in Japanese] 219 Development for Simulation Robot of Dragonfly's Wing Motion(part 1)  [in Japanese]

This research work aims to develop the simulator of dragonfly's wing motion used for the observation of flow patterns around the wings under unsteady state conditions. As the first step, the lift and drag coefficient of dragonfly's wing are measured by changing the attack angle step by step, in which the selection of the range of attack angle is based on the high-speed video image of dragonfly's free flight. It is made clean the effect on the lift and drag coefficients experimentally.
