摘要
对硼镁高能贫氧推进剂的能量特性进行了系统的理论分析研究，并探讨了高能组分对该类贫氧推进剂能量性能的影响。研究结果表明，在硼镁高能贫氧推进剂中减少镁粉含量（或增加硼粉含量），贫氧推进剂的比冲升高。在一定范围内，增加混气比有助于提高固体火箭冲压发动机的比冲。硼镁贫氧推进剂中采用ＣＬ－２０等高能组分可以显著提高其能量。而采用叠氮类含能粘合剂取代惰性粘合剂时，对提高贫氧推进剂的能量不利。
Based on the thermodynamics calculation results,the performance characteristics of boronmagnesium fuelrich propellants were investigatedThe action of high energy ingredients on performance of the propellants was also studiedThe results show that increasing the boron content or decreasing the magnesium content results in the specific impulse increase of the propellantThe specific impulse will increase with the airtofuel ratioThe addition of high energetic ingredients such as the CL20,will greatly increase the specific impulse of the propellantHowever,the substitution of the energetic binder for the inert hydrocarbon binder will result in the decrease of the specific impulse of the propellant
