The invention provides a flapping wing design method with low power consumption and thrust increasing characteristics, a flapping wing and a long-endurance flapping wing aircraft. When the ornithopter flies, the driving mechanism drives the flapping wings to perform single-degree-of-freedom flapping motion, the wing surfaces generate optimal passive deformation matched with the flight speed under the action of aerodynamic force, deformation and motion of wings in the flight process of birds in nature are simulated, and the design of bionic wings with high thrust, high lift and low power consumption is realized; the flapping wings have better thrust characteristics, the trimming frequency is reduced, so that power consumption is greatly reduced, the shape of a fuselage shell meets the aerodynamics requirement, the resistance effect caused by the fuselage is reduced, and the fuselage has the advantages of being light in weight, good in impact resistance effect and the like due to the section shape, the material and the structural form of the fuselage. And the requirements of typical flight states such as cruise flight and belly landing are met.

    本发明提出一种具有低功耗增推特性的扑动翼设计方法及扑动翼和长续航扑翼飞行器。扑翼飞行器飞行时,驱动机构驱动扑动翼进行单自由度扑动运动,翼面在气动力的作用下产生与飞行速度匹配的最佳被动变形,模仿了自然界鸟类飞行过程中羽翼的变形与运动,实现了大推力高升力低功耗仿生翼设计;扑动翼具有更好的推力特性,降低了配平频率,从而大幅降低功耗,机身外壳形状满足空气动力学要求,减少了机身带来的阻力效应,而且机身的截面形状、材料以及结构形式使机身具有重量轻、抗冲击效果好等特点,满足巡航飞行和机腹降落着陆等典型飞行状态的要求。
