    • The invention is directed to a formable homogeneous propellant composition and to a process employing same for production of a self-supporting formed propellant charge. The propellant composition comprises a mixture of propellant grains and solvent-filled microcapsules in proportions suitable for consolidation under pressure to form the self-supporting formed propellant charge. The solvent-filled microcapsules comprise solvent suitable for partially solvating the propellant grains. The mixture of propellant grains and solvent-filled microcapsules are placed in a forming mold under sufficient pressure to rupture at least a substantial portion of the microcapsules. Pressure is maintained for a time sufficient to form the self-supporting formed propellant charge, after which the propellant charge can be removed from the forming mold and cured by exposure to drying heat.
    • 本发明涉及一种可成形的均质推进剂组合物及其相应的方法,用于生产自支撑形成的推进剂装料。 推进剂组合物包含推进剂颗粒和溶剂填充的微胶囊的混合物,其比例适于在压力下固化以形成自支撑形成的推进剂装料。 溶剂填充的微胶囊包含适用于部分溶剂化推进剂颗粒的溶剂。 将推进剂颗粒和溶剂填充的微胶囊的混合物在足够的压力下放置在成型模具中以至少大部分微胶囊破裂。 压力保持足以形成自支撑形成的推进剂装料的时间,之后推进剂装料可以从成形模移除并通过暴露于干燥热固化。
