The results show that the camber deformation may play an important role in lift and drag coefficients. The positive camber deformation of the hindwing during the downstroke generates the vertical force, whereas negative camber deformation of the wing during upstroke generates thrust force. The freely flying dragonfly's hindwings play an important role in providing a stable lift force, and the forewings are very important for controlling flight behavior, such as turning, climbing and so on.
建立了自由飞行昆虫运动测量系统，开发了结合条纹投影和昆虫翅膀特征点测量翅膀变形和身体姿态的方法，首次测到了自由飞行昆虫运动翅膀变形和各种相关角度，速度、加速度，身体位置与姿态，通过分析比较直飞和转弯各个运动参数，认为蜻蜓的飞行控制主要由前翅完成，而后翅主要用于产生升力。
