研究证明,AP系复合推进剂的粘合剂中能量越高燃速也越高。在本试验压力范围内供试验用的推进剂出现燃烧中断,当粘合剂中AMMO含量为80%以上时,在4MPa压力下燃烧中断,并有推进剂的绝热火焰温度越高燃速越高的趋势。推进剂的燃烧热显示,在粘合剂中AM-MO含量在80%以下时,AMMO含量越多燃烧热越高,而燃烧热越高绝热火焰温度也越高。推进剂的燃烧热越高燃速也越高。已知叠氮化聚合物单体燃速的速率决定阶段是凝缩相反应,本研究证明,在AP系复合推进剂中从气相到燃烧表面的热流束影响推进剂燃速的速率决定阶段。
Studies have shown that, AP series composite propellant binder, the higher the energy burning rate is higher. In the test pressure range for the test of the propellant burning interruption, when the adhesive AMMO content of 80% or more, the pressure at 4MPa burning interrupted, and the advent of the propellant flame temperature is higher the higher the burning rate the trend of. The heat of combustion of the propellant shows that the higher the AMMO content is, the higher the heat of combustion is, and the higher the heat of combustion is, the higher the adiabatic flame temperature is. The higher the combustion heat of the propellant, the higher the burning rate. It is known that the rate-determining phase of the azidated polymer monomer combustion rate is a condensation-phase reaction and this study demonstrates the rate-determining phase in which the heat flux from the gas phase to the combustion surface affects the rate of burning of the propellant in the AP complex propellant.
