弹体入水弹道研究综述

A Review of the Body′s Water Entry Ballistics Research

描述了弹体入水过程 4个阶段 :撞击、流动形成、开空泡、空泡闭合的基本特征 .分别讨论了弹体形状、入水角、入水速度、攻角、初始角速度和水域环境对入水弹道的影响 .综述了弹体入水弹道的实验与理论研究概况 。

This paper describes the essential features of four stages of the pellet water entry: collision, formation of the flow, cavity opening, cavity closure. The influence of the pellet′s shape, the angle of water entry, the velocity of water entry, the attack angle, the initial angular velocity and the environment of water surface on pellet water entry ballistics are discussed. The outline of experiment and theory research about pellet water entry ballistics are reviewed. The further research work is presented.
