近水面高速战斗部是一种能够在近水面发射及水面高速滑跳的新概念水雷武器作战系统,通过海面杂波能够实现高效突防,达到出其不意的攻击目的,了解其滑跳运动过程中受力特性是实现战斗部稳定跳跃式航行的基础。基于不可压雷诺时均N-S方程,空气与水交界面问题采用VOF方法,湍流模型采用剪切应力输运(Shear Stress Transport model,SST)模型,对近水面高速战斗部滑跳过程进行仿真,对比分析了质量对滑跳过程受力特性的影响。通过仿真计算得到,在战斗部总体配置中,应通过增大纵倾方向的惯性矩或调整战斗部前后翼的尺寸和安装角度来减小战斗部反弹后的迎角,同时,在条件允许的情况下,应适当能提高战斗部的质量。
The near-surface high-speed warhead is a new concept of mine-fire weapon combat system capable of launching near surface and high-speed skating on the surface of the water. It can achieve high efficiency penetration by sea clutter and achieve unexpected purpose of attack. Force characteristics are the basis for achieving stable and leapfrog voyages in warheads. Based on the incompressible Reynolds-averaged Navier-Stokes equations, the VOF method is used for the air-water interface problems, and the turbulent model is simulated using the Shear Stress Transport model (SST) model. The effect of mass on the force characteristics of the slipping process is analyzed. Through the simulation calculation, in the overall configuration of the warhead, the attack angle after the rebound of the warhead should be reduced by increasing the moment of inertia in the trim direction or by adjusting the size and installation angle of the front and rear wings of the warhead. At the same time, In the circumstances, the quality of warheads should be appropriately enhanced.
