Abstract: 

Recently, the designers of gun and ammunition need different models to simulate the initial design concepts especially to make decision about optimum charge design and overall parameters of gun systems by using a mathematical optimization code coupled with the interior ballistic code. Nowadays, there are several available tools simulating the interior ballistic process; each tool has its advantages and its accessible outputs. In this work, interior ballistic lumped parameter model (IBLPM), with single propellant and mixed propellant, and one dimensional two-phase flow model (1D-TPFM) are carried out. Comparisons between obtained results for the different tools and experimental results are presented. This study is valuable to decide which interior ballistic tools will be appropriate to couple with the optimization codes for obtaining the optimum charge design.

Keywords: 

interior ballistic, lumped parameter model, two phase flow model
