摘　　要：在电能密度范围 0 5 8～ 0 98kJ/ g、装填密度范围 0 3～ 0 35 g/cm3条件下 ,实现了电热化学炮固体药点火、等离子体单脉冲或双脉冲增强燃烧过程 ,进行了等离子体燃烧增强特性分析 ,并结合数值分析对等离子体射流理想的注入时机予以了讨论 。The process of solid propellant ignition, single pulse or double pulse plasma enhanced burning in solid propellant electrothermal chemical (SPETC) launcher was accomplished with a loading density of 0.3 ～ 0.35 g/cm 3 and an electric density of 0 58～0 98kJ/g, and the one dimensional SPETC two phase model was used for the analysis of the enhanced burning effect. Based on experiments, the influence of plasma injection occasions to ballistic performance was discussed, and the experiments indicate that plasma injection just after peak pressure can extend the pressure flat roof and improve ballistic performance effectively.
