英文摘要: This project is to develop and explore forewing-hindwing flapping flow characteristics and high-lift mechanism dragonfly, and to set a TR-TomoPIV, six components dynamic force transducer and flapping mimetic mechanism joint measurement system.Flow field around flapping wing mechanism and six components of aerodynamic during hovering and forward flight of dragonfly and the influence of forewing-hindwing flapping parameters will be tested with the joint measurement system and flapping wing inertia force and aerodynamic testing system. Detailed analysis of dragonfly flapping wing flow characteristics of flow around forewing and hindwing will be conducted. Power requirement analysis and other methods will be used to reveal the new high-lift mechanism of dragonfly wings. This project not only has important scientific significance for promoting the development of bionic flapping wing aerodynamics, but also provides new concepts and effective way for the development of advanced high-performance technology MAV.
