| 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。 |

| Abstract: |
| 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-tetrahydrofuran 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 propellants 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 existed interaction between OME and azide groups in BAMO-THF copolyether. |
