Numerical Simulation of Interior Ballistics and Firing Experiment of Super-high Firing Rate Gun

A firing experiment of a new super-high firing rate gun with three and five serial loading projectiles is tested,and get the bore pressure data.Its classical model of interior ballistics is established and a numerical simulation is conducted.Computational results are consistent with the experimental ones.This shows that the simulation of the interior ballistic process is feasible.The effect of the variation of firing rate upon the interior ballistics characteristics and the muzzle velocity were discussed in detail,and get the regulations.The researches can be used for reference for subsequent research.
