水下发射发射筒注水情况仿真分析

Simulation and Analysis of Water Injection of Underwater Launch Tube

水下发射过程,导弹离开发射筒后,海水将倒灌进发射筒并形成水锤,对水下发射装置的结构等造成影响。通过对导弹离开发射筒后的第1个水锤周期的仿真,得到了该周期筒底压力与注水量的变化情况,并通过分析得到发射筒注水的规律,探究了水锤产生的机理,得出了该周期中各阶段特征,为对水锤作用更深一步的研究提供了原理性的分析。

During the underwater launch process, after the missile has left the launch tube, seawater will come into the launch tube and form a water hammer, which may affect the structure of underwater launch equipment. By simulating the first cycle of water hammer after the missile has left the launch tube, the change of the pressure at the bottom of the launch tube and water injection are obtained. By analyzing the process, the regular pattern of the injection of the launch tube is obtained, and by exploring the mecha- nism of water hammer, the characteristics of each stage of the cycle is understood, which provides some principle analysis of the future research.
