| 摘 要： | 采用动态热分析(DMA)方法研究了某丁羟推进剂贮存老化的动态力学性能,借助时间一温度叠加原理,获得时间位移与频率对数的关系曲线及WLF方程的常数,并计算得到固体火箭发动机点火瞬间的推进剂药柱的临界温度tc,并用tc数据预估了发动机点火瞬间推进剂药柱不会由高弹态向玻璃态转变,不会发生断裂与结构完整性破坏.

| Abstract: | Dynamic mechanical property of HTPB propellant after storage aging was investigated by using dynamic mechanics analysis method.The relational graph of time displacement with logarithm of frequency and the constant of WLF equation were obtained based on time-temperature superposition.Critical temperature tc of propellant in ignition instant for solid rocket propellant was also calculated.It was predicted that HTPB propellant would not change from high elasticity state to glass state and destroy structure int... |
