Abstract:

分别采用基团加和法和燃烧热法得到含不同聚(3, 3′-双(叠氮甲基)氧杂环丁烷)(PBAMO)和氨基甲酸酯硬段含量P(BAMO/AMMO)基含能热塑性聚氨酯弹性体(ETPE)的生成热。研究了PBAMO、氨基甲酸酯硬段的含量对ETPE生成热的影响。采用最小自由能法优选出一组P(BAMO/AMMO) ETPE基推进剂配方。计算了理论比冲。测试了P(BAMO/AMMO) ETPE基推进剂的静态拉伸强度、断裂延伸率、摩擦感度、撞击感度和燃速压力指数。结果表明,随着PBAMO质量的增加、氨基甲酸酯硬段含量的降低,P(BAMO/AMMO) ETPE的生成热增加。优选的15/5/20/38.5/18/3.5-P(BAMO/AMMO)/Bu-NENA/RDX/AP/Al/催化剂推进剂的理论比冲为2699.51 N·s·kg-1(燃烧室压强为10 MPa)。此推进剂的静态拉伸强度为1.22 MPa,断裂延伸率为11.37%。包覆固体填料可显著降低推进剂预混物料的机械感度,使特性落高H50增加37 cm,摩擦感度下降36%, 6~15 MPa压力范围内的燃速压力指数n=0.37
