摘　　要：目前,国际上正在开发的3艘全海深载人潜水器各自采用了不同的水动力设计思想。文章用计算流体力学方法对三艘载人潜水器的水动力特点进行了深入分析和综合比较。DEEPSEA CHALLENGE和Deepsearch潜水器采用了鱼雷外形来减小阻力而Deep Flight Challenger通过安装水翼来提高航行速度。这两种方法都能满足提高下潜、上浮速度的要求。文中的研究将有益于全海深载人潜水器研发工作。Currently there are three full ocean depth manned submersibles being developed using dif-ferent hydrodynamic principles. The purpose of this paper is to provide an in-depth analysis of the hydrodynamic characteristics of the three manned submersibles by using the Computational Fluid Dynamics （CFD） method. A comparative study of the above three manned submersibles is carried out. It is found that both DEEPSEA CHALLENGE and Deepsearch submersibles use a torpedo shape to reduce the vertical drag while Deep Flight Challenger uses hydrofoils to accelerate its motion. Both methods can meet the need of the descent and ascent rate requirements. This preliminary study would be helpful to the development of the full ocean depth manned submersible.
