该文利用自行研制的底火燃烧特性综合测试系统,测出底火随贮存年份增长其燃烧特性的变化规律,与火炮射击时底火对P_m、V_0、rv_0变化规律的比较,建立了P_m、V_0与底火燃烧特性变化的关系式,从而为库存弹药底火的检验提供了科学依据,为库存弹药底火的内弹道性能模拟研究奠定了基础.此外,对新的弹道系统设计、研究,选择底火燃烧性能有一定的参考价值. In this paper, the self-developed bottom-fire combustion characteristics comprehensive test system was used to measure the variation of bottom-fire combustion characteristics with storage years. Compared with the changes of P_m, V_0 and rv_0, Combustion characteristics of the relationship between changes in the inventory of ammunition at the end of the fire test provides a scientific basis for the inventory of ammunition at the end of the fire trajectory simulation of the foundation laid the foundation.In addition, the new ballistic system design, research, select the bottom of the fire performance of a certain The reference value.
