Interior Ballistics Simulation of Modular Charge Gun System Using Matlab

Abstract:

Calculation and simulation of the interior ballistic precedes the design of gun and charge construction. Modular charge system is the major development direction of large caliber howitzer, and will be as a replacement of current bag charge. It is necessary to develop a common program used to simulate interior ballistic environment of modular charge, which is a complex composite propellant charge. The characteristics of modular charge construction and the difference compared with traditional charge style were introduced at first. A simulation program of was developed based on lumped-parameters interior ballistic model using Matlab/Simulink development environment, which is relative simple, but, very suitable first stage design of interior ballistic of modular charge system. The program includes four modules, input parameters, core simulation code, calculation of form equations and data processing. The simulation results are agreeable with the experimental values according to the parameters of a certain 155mm gun. Furthermore, the program could be used in the numerical calculation of single charge or bag charge by adjusting some items.
