用快速降压法进行过固体复合推进剂(PBAN+AP)熄火性能的试验研究。采用一种根据绝热过程(或等熵过程)的解析方法和萨默菲尔德的燃速规律来予估压力的衰减。假定排气孔的打开速度是时间的抛物线函数;还提出了一个“绝热—等熵组合过程”的模型以改善这种予估的方法。
Experimental study on flameout performance of solid composite propellant (PBAN + AP) by rapid depressurization method. An analytical approach based on adiabatic processes (or isentropic processes) and Summerfield’s rate of burning are used to estimate the pressure decay. Assuming that the vent opening speed is a parabolic function of time, a model of “adiabatic-isentropic combination process” is also proposed to improve this presumed method.
