The ornithopter comprises a rack, a power assembly, a conical rolling assembly, a torsion assembly and the wings, the power assembly is installed in the rack and used for outputting power, and the conical rolling assembly comprises a fixing shaft, wing swing pieces and connecting pieces; the torsion assembly comprises a sliding block, a first connecting rod and a second connecting rod, the front edge of the wing is connected to the wing swing piece, and the inner side edge of the wing is connected to the other end of the second connecting rod. The air resistance is optimized by twisting the wings of the wings in the flapping process of the wings, in the downward flapping process, the wings are completely flattened to maximize the lift force, and in the upward flapping process, the wings are twisted by a certain angle to reduce the stress area, so that the air resistance is remarkably reduced. Therefore, the energy consumption is reduced, the lift force in the downward flapping process and the net lift force of the aircraft are improved, and the aircraft has better adaptability and stability in different flight states.
本发明公开一种机翼可扭转的扑翼飞行器,包括机架、动力组件、圆锥滚动组件、扭转组件和机翼,所述动力组件安装于所述机架中用于输出动力,所述圆锥滚动组件包括固定轴、机翼摆件和连接件,所述扭转组件包括滑动块、第一连杆和第二连杆,所述机翼的前缘连接于所述机翼摆件上,所述机翼的内侧缘连接于所述第二连杆的另一端。通过机翼在扑动过程中扭转机翼的翅膀来优化空气阻力,在下扑过程中,翅膀完全平展以最大化升力,而在上扑过程中,翅膀通过扭转一定角度来减小受力面积,从而显著降低空气阻力。由此减少了能量消耗,提高下扑过程中的升力和飞行器的净升力,使得飞行器在不同飞行状态下具有更好的适应性和稳定性。
