扑翼飞行器气动力测量技术研究进展与展望

Research Progress and Prospect of Aerodynamic Measurement Technology for Flapping Wing Aircrafts

扑翼飞行器是一种仿照鸟类飞行的新概念小型无人飞行器,区别于传统固定翼和旋翼飞行器,它主要通过机翼扑动与空气相互作用来提供飞行动力,从而实现飞行器的姿态变动。扑翼飞行器气动特性测试的实质是揭示在非定常流场环境下,扑翼飞行器气动力的产生机制,以及相关扑翼飞行器设计参数对气动特性的影响。通过气动试验方法为扑翼飞行器飞行控制和结构优化等研制工作提供数据支持,将对新型扑翼飞行器理论研究以及飞控品质的提升起到巨大的推动作用。

The flapping wing aircraft is a new concept - based small unmanned aerial vehicle modeled by bird flying. It is distinguished from traditional fixed - wing and rotorcrafts and its lift and thrust forces are provided by flapping wings. The aerodynamic characteristics of the flapping -wing aircraft are tested to explore the generation mechanism of the aerodynamic force of the flapping - wing aircraft in the unsteady flow field environment and the effects of the relevant parameters of the proposed flapping - wing aircraft on the aerodynamic characteristics. With the help of data provided by aerodynamic test, the work of flapping wing flight control and mechanical structural optimization can be improved obviously. This study will play a huge role in promoting the design of flapping wing aircrafts and the control quality improvement.
