摘　　要：根据海洋岛礁环境,设计了一款无人机。为满足设计要求,采用大展弦比、上单翼与V型尾翼的气动布局和倾转矢量动力方案,采用非结构网络和SST κ-ω湍流模型对设计无人机进行计算分析,并利用实时仿真系统对该设计进行了全自动飞行验证。计算和仿真结果表明所设计的无人机气动性能优良,满足岛礁的使用需求。According to the requirements of marine reef environment, an UAV is designed. In order to meet the design requirements, the aerodynamic layout of high aspect ratio, upper single wing and the scheme with tilt power and vector propulsion are adopted. The design scheme is calculated and analyzed by using unstructured network and SST κ-ω turbulence model, and the real-time simulation system is used to verify the design in full automatic flight. The results show that the UVA has excellent aerodynamic performance and can meet flight requirements in the marine reef environment.
