摘　　要：V形尾翼由于其出色的气动性能和相对较轻的质量,在大展弦比、长航时的察打一体式无人机上有广泛的应用。轻量化设计是提升无人机续航时间的主要途径,基于响应面法,对设计得到的V形尾翼的翼展长度、翼肋数量以及蒙皮厚度进行了优化,得到了一种新型V形尾翼构型,通过强度校核、模态分析及外流场仿真分析对比,结果表明新得到的V形尾翼在满足强度和结构动态特性要求的同时,能够保持气动性能的相对稳定,结构质量相比优化前降低22.88%。最后采用熔融沉积建模(fused deposion modeling,FDM)增材制造技术对得到的轻量化V形尾翼进行试制,对比优化前后V形尾翼的质量,变化幅度与仿真基本一致,证明该设计方法可行。Due to its excellent aerodynamic performance and relatively light weight,the V-tail has a wide range of applications in high aspect ratio and long endurance integrated unmanned aerial vehicles(UAV).Lightweight design is the main way to improve the endurance of unmanned aerial vehicles.Based on response surface methodology,the wingspan length,number of ribs,and skin thickness of the designed V-tail were optimized,resulting in a new V-tail configuration.Through strength verification,modal analysis,and external flow field simulation analysis,the results show that the newly obtained V-shaped tail can maintain relatively stable aerodynamic performance while meeting the requirements of strength and structural dynamic characteristics,and the structural quality is reduced by 22.88%compared to before optimization.Finally,the lightweight V-tail design was successfully prototyped using fused deposition modeling(FDM)additive manufacturing technology,and the experimental results confirmed a weight reduction consistent with the simulation findings,validating the feasibility of the optimization approach.
