摘　　要：近年来,水-空跨介质航行器因具有立体跨域优势而成为研究热点,但水-空跨介质航行器平台总体的现有设计水平阻碍了其在实际复杂环境中的推广和应用。文中基于仿生变体技术,提出一种新型仿生水-空跨介质航行器结构。针对航行器外形特点,设计了2对变体水翼和折叠空翼,并开发出变体执行机构,以实现水翼、空翼的展开和收缩。为保证该航行器在多模态下的优良性能,对其在水下、水面和空中模态的水动力性能和气动性能进行了计算流体动力学数值仿真研究。结果表明,该航行器不仅可实现水下定深潜行、水面高速航行以及空中定高飞行的跨域作业,而且兼具水下隐蔽性和空中机动性等优势。In recent years, water-air cross-domain vehicles have become a research hotspot owing to their stereo cross-domain advantages. However, the design level of existing water-air cross-domain vehicles is limited, which hinders their popularization and application in an actual complex environment. Based on the bionic variant technology, a novel bionic structure of a water-air cross-domain vehicle is proposed in this paper. Two pairs of variant hydrofoils and folded air wings were designed based on the shape characteristics of the vehicle. Moreover, various actuators have been developed to realize the expansion and contraction of hydrofoils and air wings. To ensure the excellent performance of the vehicle in multi-mode, the hydrodynamic and aerodynamic performances of the undersea vehicle, water surface, and air modes were studied using computational fluid dynamics numerical simulation. The results show that the vehicle can achieve underwater running at a fixed depth, high-speed sailing on the water surface, and fixed-altitude flight in the air. The water-air cross-domain vehicle can not only realize cross-domain operation, but also has the advantages of underwater concealment and air mobility.
