摘　　要：为深入探索蛙人用水下空泡火箭弹弹道特性,以某型火箭弹为研究对象,建立水下弹道方程,基于VC++语言编程,对有/无动力两种弹道特性进行仿真分析。结果表明,初始速度为70 m/s时,无动力弹在0.5 s内衰减至5 m/s后趋于稳定,有动力弹在1 s内衰减至大约38 m/s后趋于稳定;且不同射角对水下弹弹道特性具有显著影响,该方法可为新一代水下单兵兵器技术发展提供参考。An underwater trajectory equation is established in this paper to deeply explore the trajectory characteristics of frogman underwater cavitating rocket,and the simulation analysis of two kinds of trajectory characteristics with and without power is carried out based on VC++language programming.The results show that when the initial velocity is 70 m/s,the unpowered projectile decays to 5 m/s in 0.5 s,and the dynamic projectile attenuates to about 38 m/s within 1 s.The different firing angles play a significant role in the underwater ballistic characteristics.This method can provide reference for the development of the new generation of underwater single weapon technology.
