Interior Ballistic Numerical Simulation of Hyper Firing-Rate Weapon Under Condition of Intensive Coupling

Aimed at disadvantages in the range of theory and experiment to apply classical interior ballistics theory to hyper firing-rate weapon,essential research on hyper firing rate weapon under the condition of intensive coupling was introduced.The physical model of hyper firing rate weapon under the condition of intensive coupling was put forward.The mathematical model of interior ballistic was established.Then the numerical simulation in the process of interior ballistic was carried out by means of Matlab7.1 language and program.The influence regularities of variable firing rate(40 000 round/min and 60 000 round/min)on the interior ballistic performances were analyzed.
