含镁铝富燃料推进剂低压燃速规律研究

Study of Burning Rate in Low Pressure Mg/Al Fuel-rich Propellant

以成熟的含镁铝富燃料推进剂配方为基础选择制备推进剂的候选物,制备出均匀性和稳定性良好的含镁铝富燃料固体推进剂,并对影响该推进剂的燃速不确定度的因素进行了初步分析。结果表明,所制备的含镁铝富燃料推进剂燃速具有较好的均匀性和稳定性,其扩展不确定度小于2.0(k=2)。

Based on the mature formulation of magnalium fuel-rich propellant, the burning rate of the magnalium fuel-rich propellant with good uniformity and stability has prepared. The effects of various factors for burning rate uncertainty on magnalium fuel-rich propellant are ana- lyzed. The results show that the burning rate of magnalium fuel-rich propellant which we prepared has good uniformity and stability, its extended uncertainty is less than 2. 0.
