摘要

摘要: 多段柔性变体扑翼模仿海鸥翅膀的复杂运动.观察海鸥翅膀的运动周期，设计了包含慢频率扑动、展向折弯、弦向扭转和结构柔性变形的扑翼模型，并应用准定常方法计算气动力，为该扑翼飞行器设计提供依据.在CATIA和3DMAX中设计多段柔性变体扑翼机的三维模型和运动模拟，制作样机进行飞行试验，研究其平飞、爬升、偏航等飞行姿态，结果表明升力和推力与数值计算结果吻合.相较于原有扑翼飞行器，多段柔性变体扑翼飞行器可以慢频率扑动飞行，调整扑翼形状.

Abstract: The multisection flexible morphing wings mimic the complex movement of seagull's flapping wings. By observing movement periods of seagull's flapping wings, a new flapping-wing model including fold, torsion, flexible morphing and slowly beating up and down was built. In order to provide the design of this ornithopter with a theoretical basis, the quasi-steady method was applied to calculate aerodynamic force. The three-dimensional model and motion simulation were built in CATIA and 3DMAX, and an ornithopter with multisection flexible morphing wing was built for flight test. Flying attitudes including level flight,climbing and yawing were studied, and test results including lift and thrust agree with the calculation. Compared with conventional ornithopters, the ornithopter with multisection flexible morphing wing can fly while flapping with a low frequency, and adjusting the shape of flapping wings.
