    • A solid rocket propellant composition having a relatively high low pressure deflagration limit (Pdl) and thereby capable of being extinguished with only a relatively small drop in combustion chamber pressure. The composition comprises a major amount of finely divided ammonium perchlorate and a minor amount of fluoroalkyl acrylate or methacrylate polymer as a binder, the weight ratio being from about 4.5:1 to about 6:1.The fluidity of the composition prior to curing can be improved by incorporating a small amount of an acrylate or methacrylate having an oxygen-containing functional group, e.g., hydroxyalkyl, epoxyalkyl and glycerol acrylates and methacrylates.
    • 固体火箭推进剂组合物具有相当高的低压爆燃极限(Pd1),从而能够仅以相对较小的燃烧室压力下降熄灭。 组合物包含主要量的细分散的高氯酸铵和少量作为粘合剂的丙烯酸酯或甲基丙烯酸氟烷基酯聚合物,重量比为约4.5:1至约6:1。组合物在固化之前的流动性可以是 通过加入少量具有含氧官能团的丙烯酸酯或甲基丙烯酸酯,例如羟烷基,环氧烷基和甘油丙烯酸酯和甲基丙烯酸酯来改进。
