摘 要: 在原有匀速刚性模型的基础上,提出考虑了扑翼扑动速率变化和形状变化的柔性扑翼模型,使之更接近鸟翼真实扑动情况。模拟计算了时柔性扑翼气动功率及扑动效率随着扑动角、来流速度等参数的变化,从气动角度解释了为何鸟在不同的飞行阶段扑翼规律各不相同,为柔性扑翼飞行器的设计提供了理论依据。 On the basis of former rigid wing model and consideration of the velocity change and the distortion of wing plane, a flapping model is developed.The paper also computes the flapping power and flapping efficiency of the flexible flapping-wing, and their changes with flapping angel, velocity, and so on. The results explain why the birds flap their wings by different rules in different flying phases, and provide referenced data for future design of ornithopter with flexible flapping-wing.
