硝胺火药热分解规律的实验研究

EXPERIMENTAL STUDY ON THE PHYROLYSIS OF NITRAMINE PROPELLANTS

用差示扫描量热(DSC)和热失重(TG)分析技术,对三种硝胺火药体系,以及它们的主要含能组分NC、RDX、NGU、双基粘结剂NNC_2的热分解规律作了实验研究。本文讨论了硝胺火药热分解的基本特征、热分解动力学数据、由热分解转变为爆燃时临界条件等随火药中RDX、NNC_2NGU/RDX、NC含量以及外部升温速率率化的规律,分析了硝胺火药热分解性质对点火和燃烧性能的影响。

Pyrolysis of NC/NG/RDX, NC/NG/RDX/NGU and nitramine composite propellant and the main compoments NC, RDX, NGU, and double-base binder NNC_2 as well was studied experimently with DSC and TG techniques. The characteristics and kinetic data of phrolysis of nitramine propellants, and the variation of critical transition condition between pyrolysis and deflagration with the content of RDX, NNC_2, NGU/RDX and NC and the heat transfer rate. The influence of the pyrolysis characteristics on ignition and deflagration of nitramine propellants was also analysed.
