The Software Design and Realization Based on Interior Ballistic Model of Multilayer Gun Propellant Charge

The interior ballistic model of multilayer propellant charge was founded. Based on the model, a software program was developed with MATLAB programming language. The structure and f/ow of the software program was introduced. The expansibility of the software program was improved by using the method of modularization. The interior ballistic process of multilayer propellant charge was simulated with the software program. And the simulation result was compared with the interior ballistic experiment of 30mm gun. The results show that simulation outcome is consistent with the result of interior ballistic experiment. The software program provides a theoretical reference for the research of interior ballistic performance of muhilayer propellant and design of propellant charge.
