Numerical Simulation Research of Interior Ballistics Character for Non-lethal Strike Weapon System

In order to adjust the transmitted energy and control the end effect, and adapt the needs of antiriot arm in the different use situation, which is a very difficult problem in non-lethal strike weapon domain. According to constant kinetic energy system theory, and in the base of choosing two-phase flow model of interior ballistics, and the Runge-Kutta scheme and MATLAB software are used to conduct numerical simulation to amelioration 18.4 mm antiriot gun interior ballistics,and by comparing the numerical analysis result with experiment result, validate the model of interior ballistics and numerical simulation correctness, the laws about combustion and flow of powder were obtained,and the influence regularities of the variation of ventage place,gas vessel cubage and ventage radius on muzzle velocity of projectile are achieved,which provides theoretical foundation for further researches on the c non-lethal strike weapon system.
