ABSTRACT Rocket propellants that contain ammonium perchlorate (AP) often have a violent response during slow heating. Two laboratory tests have been developed to determine the reaction violence of these materials. The first test was the Combustion Rate Analysis of a Slowly Heated Propellant (CRASH-P) test, which used dynamic pressure sensors to quantify the violence of the reaction. The second test used x-rays to measure physical changes in the propellants before ignition and their reaction violence through the deformation speed of the sample container. For this study, four propellant formulation modification categories were investigated. The propellants were investigated for their reaction violence and sample expansion before ignition.

在实验室规模上研究化学成分改性对高氯酸铵固体推进剂缓慢燃烧暴力的影响

摘要 含有高氯酸铵 (AP) 的火箭推进剂在缓慢加热时通常会产生剧烈的反应。已经开发了两个实验室测试来确定这些材料的反应强度。第一个测试是慢加热推进剂的燃烧率分析 (CRASH-P) 测试，它使用动态压力传感器来量化反应的剧烈程度。第二个测试使用 X 射线测量点火前推进剂的物理变化及其通过样品容器变形速度的反应强度。在这项研究中，研究了四种推进剂配方修改类别。在点火前研究了推进剂的反应强度和样品膨胀。
