摘要: 主动变形扑翼可以模仿鸟翼飞行时的复杂运动。为了了解主动变形扑翼飞行器的气动特性,在对鸟类骨骼结构和翅膀及尾翼运动规律研究的基础上,设计并制造了一种基于机器人技术的主动变形扑翼飞行器;给出了主动变形扑翼飞行器的机构运动规律函数,设计出机构运动控制系统;在低速风洞中对此飞行器进行了一系列测力试验,研究了主动变形扑翼的升力、推力特性和气动机理,以及风速、扑动频率、扑动幅度、伸展相位等参数对升力、推力的影响,并与常规扑翼进行了对比分析。试验结果表明,较之常规扑翼在相同情况下主动变形扑翼可以显著提高升力和对不同飞行状态的适应能力。

Abstract: The active morphing flapping wing can mimic the complex movement of a flying bird’s wings. In order to understand the aerodynamics of the active morphing wing ornithopter, the bird’s bone structure, the laws of motion of wing and tail were studied, an active morphing wing ornithopter was designed and built base on robotics. The laws of motion of the ornithopter were presented, a control system was designed and built. Wind tunnel tests of the ornithopter were performed in a low-speed wind tunnel. The lift, thrust characteristics and aerodynamic mechanism were studied, also the influence of wind velocity, flapping frequency, amplitude, stretch phase was investigated. The conventional flapping wing was tested as contrast. The test result shows that the active morphing wing can increase the lift and enhance ability to adapt to flight status.
