摘　　要：针对现有仿蝴蝶扑翼飞行器自身重量大、飞行效率较低的问题,设计了一种通过舵机驱动的仿生蝴蝶飞行器。通过精简结构、增大迎面面积等措施,以获得更大的升阻比和平均气动升力,并采用有限元仿真分析对此加以验证。研究结果表明:该飞行器以20°仰角飞行时的平均气动升力最大,能够克服自身重力实现扑翼飞行,基本满足在低空、小扰动环境中的飞行需求。Aiming at the problems of large weight and low flight efficiency of the existing butterfly flapping wing aircraft,this paper designs a bionic butterfly aircraft driven by a steering gear.By simplifying the structure and increasing the frontal area,a larger lift-to-drag ratio and average aerodynamic lift can be obtained and verified by finite element simulation analysis.The results show that the average aerodynamic lift of the aircraft is the largest when it flies at an elevation angle of 20°,and it can overcome its own gravity to achieve flapping flight,which basically meets the flight requirements in low-altitude and small disturbance environments.
