220 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2報)(S38-1 小型飛翔体(1),S38 生物飛行と小型飛翔体)  [in Japanese] 220 Development for Simulation Robot for Dragonfly's Wing Motion (Part2)  [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 second step, the lift and drag coefficient of artificial 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. The experimental resuts of artificial wings are compared with those of natural wings.
