水面水下两用艇集水面高速航行与水下运载功能于一体，1个平台兼具2种运行功能，可以完整执行海上特殊任务。本文首先对国外水面水下两用艇发展现状及艇型特点进行简要叙述，而后采用重叠网格技术，基于RANS方程，对水面水下两用艇及双折角双防溅条滑行艇的水面高速自由模拖曳运动（计及升沉和纵倾）进行预报，对比分析了两用艇独特的艇体外形设计对其水面高速航行时阻力特性的影响，最后讨论阻流板对两用艇水面航行性能的影响规律，为两用艇的艇型设计以及水动力性能研究提供参考。
In this paper, the high-speed dual-purpose craft which has the ability to travel above and below the water surface is introduced. The free model motion of the dual-purpose craft and double knuckles planing craft are simulated based on the overset mesh techniques and RANS approach. By comparing the numerical results, the original hullform and the hydrodynamic performance of the dual-purpose craft are analyzed, and the hydrodynamic effects of different blade deployment of interceptor for dual-purpose craft are discussed. All these results can provide a useful reference for the hullform design and hydrodynamic performance research of high-speed dual-purpose craft.
