摘　　要：系统介绍了二硝酰胺铵(ADN)燃烧的最新研究动态,综述了国内外近年来报道的ADN燃烧时发生的物理化学变化、ADN燃烧机理、催化剂/ADN混合物燃烧性能以及ADN基固体推进剂燃烧特性的最新研究进展。首先指出了ADN的燃烧主要受凝聚相反应控制,ADN燃烧波结构包括固相层、泡沫层(包括固-气和液-气)和气相层;其次,总结了ADN基固体推进剂燃烧特性的研究现状,对现有研究中存在的局限性进行了分析;最后,指出继续开发适用于ADN基固体推进剂的新型燃烧催化剂是今后研究的重点方向之一。另外,随着非异氰酸酯固化体系在ADN基固体推进剂中的应用,需进一步加深ADN基固体推进剂燃烧性能的研究,尤其是三唑环的引入对ADN热分解及推进剂中其他组分热分解的影响。The latest development trends in combustion of ammonium dinitramide(ADN)were introduced systematically,and the physicochemical process of ADN combustion,the combustion mechanism,combustion performance of catalyst/ADN mixtures,and combustion characteristics of ADN-based propellants were summarized.The combustion of ADN is mainly controlled by the condensed phase reaction,and the combustion wave structure includes a solid phase layer,a foam layer(including solid-gas and liquid-gas)and a gas phase layer.At the same time,the research of ADN-based solid propellant combustion characteristics was summarized,and the limitations of current research were analyzed.It indicates that developing novel combustion catalysts for ADN-based propellants is one of the future directions.With the application of non-isocyanate curing in ADN-based propellant,it is necessary to further deepen the study of its combustion properties,especially the effects of triazole ring on the thermal decomposition of other components in the propellant.
