    • A gas generator capable of quickly producing a large quantity of substantially solids-free nontoxic gas useful as a propellant in halon replacement fire suppression systems is provided. The double base castable propellant composition is formulated from a major amount of ammonium nitrate, a minor amount of nitrocellulose, at least one selected high energy nitrate ester plasticizer, a thermal scavenger, and at least one burning rate modification and control additive to achieve a burning rate of 0.2 inches per second or greater at 1000 psia. The burning rate is further enhanced by the configuration of the solid propellant, which is formed to have dimensions selected to enhance the burning rate. The gas generator composition and physical arrangement synergistically produce an optimally rapid burning rate.
    • 提供了一种能够在哈龙替代灭火系统中快速产生大量无固体的无毒气体,可用作推进剂的气体发生器。 双重基础浇注型推进剂组合物由主要量的硝酸铵,少量硝化纤维素,至少一种选择的高能硝酸酯增塑剂,热清除剂和至少一种燃烧速率改性和控制添加剂配制以实现燃烧 速率为0.2英寸/秒或更大,在1000 psia。 固体推进剂的结构进一步提高了燃烧速率,固体推进剂形成为具有选择的尺寸以提高燃烧速率。 气体发生器组成和物理排列协同地产生最佳的快速燃烧速率。
