摘要
无尾飞翼布局无人机具有高气动效率、结构强度以及良好隐身特性等突出优势,但也具有控制性能不佳的缺点。以某型小展弦比飞翼式无人机为研究对象,基于CFD仿真计算和风洞试验得到的气动数据,分析该型无人机的稳定特性,讨论了嵌入面式操纵面对小展弦比无人机的优劣。主要分析该无人机纵向模态,进而设计了飞行控制系统,搭建了飞机模型,并使用MATLAB仿真飞行过程,验证了控制系统的可行性,为飞翼无人机控制系统的设计提供参考。
Tailless flying wing UAV has excellent performance in aerodynamic,structure and stealth capability,but also has the shortcoming of poor controlling ability. A tailless flying wing UAV with low aspect-ratio is studied. Based on the aerodynamics data calculated by CFD and wind turner data,the stability characteristics are analyzed. The influence of Spoiler/Slot Deflector on the UAV with low aspect-ratio is discussed. After analyzing the longitudinal modes,the flight control system is designed,the airplane mode is set up. By simulating the whole flying process in MATLAB,the feasibility of the control system is verified,which can give a reference for other similar flying-wing configuration designing.
