A double base propellant composition having well- platonised ballistics at low burning rates consists of nitroglycerine (NG), nitrocellulose (NC) at least one lead compound and at least one copper (II) salt of an aliphatic dicarboxylic acid. The copper salt preferably comprises copper succinate, and the lead compound may include any of those known as ballistic modifiers in the propellant art. A preferred composition, having a platonised burning rate of 2.3 mm s-1 at a chamber pressure of 2-3 MPa, comprises by weight 35.1% NC (12.6% nitrogen), 41.6% NG, 8.3% triacetin, 10.7% sucrose octa-acetate, 0.3% 2- nitrodiphenylamine, 1.2% p-nitromethylaniline, 1.0% copper (II) succinate and 1.8% lead acetophthalate.
一种双基推进剂组合物在低燃烧速率下具有良好的塑化弹道,该组合物由硝化甘油 (NG)、硝化纤维素(NC)、至少一种铅化合物和至少一种脂肪族二羧酸的铜(II)盐组成。铜盐最好是琥珀酸铜,铅化合物可以是推进剂领域中任何一种已知的弹道改性剂。一种优选的组合物,在 2-3 兆帕的室压下具有 2.3 毫米/秒的镀层燃烧速率,按重量计包括 35.1% 的 NC(12.6% 的氮)、41.6% 的 NG、8.3% 的三醋精、10.7% 的八乙酸蔗糖、0.3% 的 2-硝基二苯胺、1.2% 的对硝基甲基苯胺、1.0% 的琥珀酸铜(II)和 1.8% 的邻苯二甲酸铅。
