中文摘要:
      目的 快速、准确地评估固体推进剂贮存寿命。方法 在4个不同升温速率下获得固体推进剂的热流信号，根据等转化率原理，利用AKTS热反应动力学软件获得相应的动力学参数及动力学模型，同时开展60℃热老化试验，选用适当的数学模型评价固体推进剂贮存寿命。结果固体推进剂在25℃的贮存寿命为16年。结论 利用等转化率原理可准确获得固体推进剂反应速率常数，再利用单个温度点加速老化试验能快速得到固体推进剂的贮存寿命。
英文摘要:
      Objective To evaluate thestorage life of solid propellant quickly and accurately.Methods Heat flow signals of propellant were attained at four different heating rates. Thermal reaction kinetic parameters and model for propellant were obtained using the AKTS heat reaction kinetics software, which was based on the equivalent transformation rate principle. A heat aging test was also carried out at 60℃. And then the storage life of solid propellant was evaluated using appropriate mathematic model.ResultsThe storage life of solid propellant was16years at25℃. Conclusion The reaction rate constant could be obtained accurately using the equivalent transformation rate principle. The storage life of solid propellant was concluded quickly through a single temperature heat aging test.
