The invention relates to a wing based on a bionic fin-shaped front edge and used for flapping wing dynamic stall control, belongs to the technical field of aircraft design and manufacturing, and solves the problem that in the prior art, flapping wing dynamic stall cannot be effectively controlled while the aerodynamic characteristics of flapping wings cannot be considered. According to the invention, the spanwise and normal motion of the fluid is enhanced through the bionic fin-shaped leading edge, and multiple groups of flow vortex pairs are passively introduced to enhance vorticity and momentum exchange between the fluid, so that the safety and stability of the ornithopter in actual flight can be effectively improved; the bionic fin-shaped leading edge is used for replacing a traditional linear leading edge, the design of all hardware can be completed at a time by adopting an integrated forming process, and the bionic fin-shaped leading edge is simple in structure, easy to form, light in maintenance and convenient to use; the energy of the flapping wings does not need to be consumed, so that the flapping-wing aircraft has better endurance service performance; through directional adjustment of the wave height and the wavelength, the dynamic stall control efficiency can be effectively improved on the premise that the aerodynamic characteristics of the flapping wings are not affected.
本发明涉及一种基于仿生鳍型前缘的用于扑翼动态失速控制的机翼,属于飞行器设计与制造技术领域,解决了现有技术中无法有效控制扑翼动态失速的同时兼顾扑翼气动特性的问题。本发明通过仿生鳍型前缘增强流体的展向和法向运动,被动引入多组流向涡对增强流体间的涡量和动量交换,能够有效提升扑翼飞行器实际飞行时的安全性和稳定性;利用仿生鳍型前缘替代传统线形前缘,采取一体成型工艺即可一次性完成所有硬件上的设计,简结构、易成型、轻维护、便使用;无需消耗扑翼自身能量,使得扑翼飞行器有更好的续航服役性能;通过对波高和波长的定向调整,能够在不影响扑翼气动特性的前提下有效提升动态失速控制效率。
