Treatment of deterred propellants in interior ballistic calculations

Abstract

In the paper the procedure for determination of deterred propellant characteristics that are necessary as input parameters in interior ballistic calculations is given. The basic features of developed model for interior ballistic cycle calculation of systems with deterred propellant propelling charge are presented. The model verification is carried out through comparison of computational results with American experimental data of 20 mm rounds with ball propellant propelling charge.
