摘要
将燃烧催化剂引入太根发射药中,利用密闭爆发器静态燃烧实验研究了这些燃烧催化剂对太根发射药燃烧性能的作用效果。结果表明,某些特殊的燃烧催化剂,可较好地降低该类发射药局部燃烧压强范围内的燃速压强指数,降低压强指数的压力范围与所用催化剂的种类有关。研究还发现,邻苯二甲酸铅有缩短太根发射药燃烧时间、提高燃烧速度、增加气体生成猛度的作用;含铜金属盐有抑制太根发射药燃气生成猛度的作用。
Some catalysts are putting into TEGDN gun propellants and the effect of these catalysts on combustion properties of TEGDN gun propellant is studied through closed bomb test. The result shows that, certain combustion catalyst can decrease the pressure exponent of part of combustion pressure region of TEGDN gun propellant, the pressure region decreased is related to the kind of catalysts. Lead phthalic acid can shorten combustion time, improve burning rate and increase combustion gas generation brisance of TEGDN gun propellant. Copper salt can depress the combustion gas generation brisance of TEGDN gun propellant.
