Experimental study on flight performance of dragonfly during climbing

  • 摘要: 昆虫真实飞行过程中的飞行特征是仿生流体力学机理研究的基础和关键。本文针对蜻蜓(黄蜻)大、小爬升角2种飞行状态的运动规律和动力学特性展开研究,根据蜻蜓的趋光特性诱导其进行爬升飞行。采用2台光轴相互垂直的高速摄像机进行拍摄,通过特征点匹配和三维重构方法准确地捕捉了2种爬升飞行过程中蜻蜓身体和翅膀的运动参数,并进行动力学特性对比分析。实验结果表明:蜻蜓在进行大爬升角爬升时需要的上升力大于向前的推力,最大拍动幅度比小爬升角爬升时约大40%;扑翼频率比小爬升角爬升时约大3.3 Hz,前后翅相位差相对于小爬升角爬升时减小20°以上;另外,大爬升角爬升过程中前翅前倾角度更大,这样能够使蜻蜓身体保持更大的俯仰角,翅膀能够获得更大的上升力。
