为研究GHQ推进剂的热分解性、热稳定性和热安全性,利用绝热加速量热仪(Accelerating Rate Calorimeter,ARC)测试了GHQ推进剂的绝热分解过程,得到了温度、压力实时变化曲线,最大反应速率到达时间(Time to the Maximum Rate,TMR)曲线,以及温升速率、压力随温度变化曲线。通过热惰性因子对样品在最危险状态(即绝热条件)下的起始分解温度、起始温升速率、最大温升速率、绝热温升和反应热进行了修正,并与GHT-1A推进剂进行了比较,结果表明:GHQ推进剂热稳定性低于GHT-1A推进剂,但具有良好的热安全性。
In order to study the pyrolytic, thermal and thermal safety of GHQ propellants, the adiabatic decomposition process of GHQ propellants was tested by Accelerating Rate Calorimeter (ARC). The real-time temperature and pressure curves were obtained. Time to the Maximum Rate (TMR) curve, and temperature rise rate, pressure versus temperature curve. The initial decomposition temperature, the initial temperature rise rate, the maximum temperature rise rate, the adiabatic temperature rise and the heat of reaction of the sample under the most dangerous conditions (ie, adiabatic conditions) were corrected by the thermal inertia factor and compared with the GHT-1A propellant The results show that GHQ propellant has lower thermal stability than GHT-1A propellant, but has good thermal safety.
