摘　　要：通过建立数学模型,运用数值计算方法进行求解,实现了二级轻气炮发射过程的理论计算,并以25mm/100mm二级轻气炮为基本模型,计算了其在多种不同结构参数和装填条件下的一系列发射过程。通过对大量计算数据进行系统分析,总结出结构参数和装填条件对二级轻气炮发射性能的影响规律,并根据这些规律,给出了一些提高二级轻气炮发射性能的建议.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.
