摘要/Abstract

摘要： 从热力学与动力学方面讨论了硝胺推进剂燃烧产物中的氮氧化物作为铝的氧化剂的可能性，其中用半经验量化方法ＡＭ１计算了氮氧化物、ＣＯ２与铝反应的活化能，结果表明铝与氮氧化物的反应在热力学上是自发的，在动力学上不存在大的活化能垒，从而是可行的

关键词: 硝胺推进剂;氧化氮;活化能;氧化

Abstract: Both thermodynamical and kinetical investigations showed nitrogen oxides can oxidize Al to Al 2O 3.The activation energies of reaction between nitrogen oxides,CO 2 and Al were calculated by AM1 method.The results show that there are no big energy barrier on the reaction path of nitrogen oxides and Al,while the calculated activation energy of reaction between Al and CO 2 is in good accordance with the experimental value

Key words: Nitramine propellant;Nitrogen oxides;Activation energy;Oxidation
