摘要
采用混合硝酸酯(NG+DEGDN)和2,2-二硝基丙醇缩甲醛与2,2-二硝基丙醇缩乙醛混合物(A3)研究了增塑剂对3,3-二叠氮甲基氧丁环-四氮呋喃共聚醚(BAMO-THF)复合推进剂燃速、力学性能的影响。结果表明NG+DEGDN增塑的推进剂燃速和力学性能均优于A3。另外,研究了一种有机过渡金属燃速催化剂(代号OME)对BAMO-THF复合推进剂性能的影响。在显著提高BAMO-THF复合推进剂燃速同时,OME还可提高该体系力学性能。X射线光电子能谱(XPS)分析表明OME与粘结剂中叠氮基团存在作用力。
The influences of the glyceryl trinitrate / diethyleneglycol dinitrate （ NG ＋ DEGDN） and bis（2,2-dinitropropyl） acetal / bis （2,2-dinitropropyl） formal （ A3 ） plasticizers on performances of composite 3,3-bis （azidomethyl） oxetane-tet- rahydrofuran co-polyether （BAMO-THF） propellants have been studied respectively. BAMO-THF/NG ＋ DEGDN propellants showed higher burning rates and better mechanical properties than BAMO-THF/A3 propellants. In addition, the influence of a kind of organic transition metal combustion catalyst （OME） on burning rates and mechanical properties of BAMO-THF propel- lants has also been investigated. It was found that OME could increase the burning rates of BAMO-THF propellants and improve mechanical properties for BAMO-THF propellants. XPS （ X-ray photoelectron spectra） analysis indicated that there exis- ted interaction between OME and azide groups in BAMO -THF copolyether.
