为了兼顾水下航行器和空中飞行器的优势，本文提出一种基于升力原理实现水空作业且能多次自由穿越水气界面的航行器——海空跨域航行器，应用STAR-CCM+软件，基于重叠网格方法对航行器的气动水动特性进行数值模拟，分别得到了航行器在水中和空中航行时的升阻力以及升阻力系数。通过对结果的分析，验证了该航行器可以分别满足在水中和空中航行时的升阻力要求，这对海空跨域航行器的设计有着重要的参考意义。
In order to give consideration to the advantages of underwater vehicle and air vehicle, this paper proposes a kind of vehicle that can fly in the air and water and can freely cross the water-air interface for many times, which is aerial underwater vehicle. The aerodynamic and hydrodynamic characteristics of the vehicle were simulated based on STAR-CCM+ and the overset mesh, and the lift and drag coefficient were obtained respectively in water and air. Through the analysis of the results, it is verified that the vehicle can meet the requirements of underwater and air navigation, which has important reference significance for the design of aerial underwater vehicle.
