摘　　要：本文在一定的假设基础上给出了电热发射内弹道集总参数数学模型 ,该模型包括放电管内等离子体生成、流动过程以及燃烧室内液体发射药的燃烧等过程。考虑了毛细管材料烧蚀、电离产生等离子体的机理 ,液体发射药的燃烧 ,弹后气体的压力分布。利用该模型对电热发射内弹道过程进行了数值模拟 。A lumped parameter interior ballistics model of electrothermal launching under certain assumptions is described. The model includes the process of plasma formation and its flow and combustion of the liquid propellant. It takes into consideration the ablation and ionization of capillary material and the mechanism of plasma formation. Interior ballistics of electrothermal launching is thus simulated. The simulation results has good consistency with the experimental data in particular points.
