ABSTRACT Current solid rocket propellant formulations still employ traditional ingredients utilized since the 1960s, such as hydroxyl terminated polybutadiene (HTPB). Recent advances in energetic polymer see many binders capable of providing higher specific impulse and burn rates over HTPB. As shown by calculations, even slight increases in specific impulse can drastically increase the maximum payload of a launch system. Therefore, replacing HTPB with energetic binders could provide heavy space missions the needed extra boost. Energetic binders could also be paired with chlorine-free energetic oxidizers to synergistically provide a specific impulse exceedingly higher than the current formulation while reducing pollution. A comprehensive evaluation of the synthesis, mechanical properties, and performance of various trending and overlooked energetic polymers is described. Several outstanding candidates show promising properties to replace HTPB.

新型高能聚合物和粘合剂综述——新太空竞赛的高能推进剂成分

摘要 当前的固体火箭推进剂配方仍采用自 1960 年代以来使用的传统成分，例如端羟基聚丁二烯 (HTPB)。含能聚合物的最新进展使许多粘合剂能够提供比 HTPB 更高的比冲和燃烧率。计算表明，即使比冲略有增加，也可以大大增加发射系统的最大有效载荷。因此，用高能粘合剂代替 HTPB 可以为重型太空任务提供所需的额外推动力。高能粘合剂还可以与无氯高能氧化剂搭配使用，以协同提供比当前配方高得多的比冲，同时减少污染。综合评价其合成、力学性能、描述了各种趋势和被忽视的高能聚合物的性能。几个杰出的候选者显示出有希望取代 HTPB 的特性。
