Based on establishing a mathematical model for launching process of two-stage light-gas gun and computing it numerically, the theoretical computation is accomplished. A 25mm/100mm two-stage light-gas gun is taken for the primary computing model, and lots of data are obtained by computing the model in different geometry parameters and different loading conditions. On the basis of the results of analyzing these data systematically, some laws of the effects of geometry parameters and loading conditions on the launching performance of two-stage light-gas gun are obtained. According to these conclusions, some advices on enhancing the launching performance of two-stage light-gas gun are put forward.
