  • 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.
