Abstract:
A firing experiment of super-high firing rate gun with three serial loading project iles is tested. 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 simulat ion of the interior ballistic process is feasible.The effects of the firing rate on the maximum bore pressure and the muzzle velocity are analyzed. It is shown that the f iring rate must be below a limit, in which the next propellant is ignited after the previous projection departs from the muzzle and the pressure decreases to a certain value. This avoids the interaction of the interior ballistics processes between different projectiles and reduces the velocity deviation.
