Abstract

Abstract

According to the structural characteristic of the weapon with side chamber, an equivalent model is proposed. Based on the model, two one-dimensional interior ballistic models are developed. Then, second-order TVD algorithm is employed for the computational code for both gas-phase and solid-phase equations. Finally, the model and algorithm are proved to be feasible in comparison with the experimental results of the 12.7mm caliber firing experiments.
