The Japan Society for Aeronautical and Space Sciences : Japan Aerospace Exploration Agency (JAXA), Online meeting), The insect flight is given by flapping flight properties necessary for micro-air-vehicle (MAV). Therefore, studies of insect flight are important to be developed MAV. This study is aimed to investigate the flapping flight properties of the scarab beetle. The velocity field around the flapping wing of the scarab beetle and the generation mechanism of vortex formation were visualized with smoke-wire method and particle-image-velocimetry (PIV). The flapping flight of the scarab beetle can be divided into 4 phases: upstroke, feathering (high angle of attack-low angle of attack), downstroke and feathering (low angle of attack-high angle of attack). Measured frequency in this experiment is of 92.4+/-2.8Hz. Streamlines show that the vortexes are generated during the upstroke and downstroke process. PIV shows that the velocity of downstroke process is larger than upstroke ones. These results indicate that the scarab beetle is produced substantial lift and thrust forces during the downstroke., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2130027016, レポート番号: JAXA-SP-21-008},
