Abstract

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.

Key words： frogman's cavitating rocket; underwater trajectory; mathematical modeling; simulation; characteristic analysis
