摘要
丁羟复合固体推进剂是以端羟基聚丁二烯(HTPB)为粘合剂的一类固体推进剂。在其成熟的技术体系上,根据目前存在的燃烧羽焰不清洁和燃烧效率较低的问题,介绍了新型含能材料在丁羟复合推进剂中的应用情况。为了实现燃烧羽焰的清洁性,可以使用六硝基六氮杂异伍兹烷(CL?20)、多氮化合物等高能化合物替代部分高氯酸铵(AP),而二硝酰胺铵(ADN)、硝仿肼(HNF)有希望完全替代丁羟推进剂中的AP;而为了提升铝(Al)粉的燃烧效率,可以使用三氢化铝(AlH_3)、纳米Al和各种复合Al粉。总的来说,在丁羟推进剂中应用新型含能材料应当遵循问题导向,以实现燃烧羽焰清洁性和提高铝粉燃烧效率为目标,充分挖掘无氯类氧化剂和铝基复合材料等新型含能材料的特性价值,从而进一步拓展丁羟推进剂应用范围,为推动固体动力技术在军事和民用领域的全面发展做出贡献。
In this paper,based on the mature technical system of hydroxyl terminated polybutadiene(HTPB)composite solid propellants,the new energetic material have been introduced for these formulations to obtain plume with less emission and higher combustion efficiency. According to the literature,in order to achieve the low emission of the combustion plume,high?energy compounds such as hexanitrohexaazaisowurtzitane(CL?20)and polynitrogen compounds can be used to partially replace some ammonium perchlorate(AP),whereas the dinitramide Ammonium(ADN)and nitrous oxide(HNF)are expected to completely replace AP in HTPB propellants. More importantly,in order to improve the combustion efficiency of aluminum(Al)powder,aluminum hydride(AlH3),nano?Al or various composite Al powder could be used. In general,the development of new energetic ingredients for HTPB propellants should follow the problem?oriented principle. As a result,it′s better to investigate the characteristics of such novel energetic ingredients,and thereby the practical applications of HTPB propellants could be extended,which may promote solid?power technology in both military and civilian applications.
