摘　　要：以成熟的镁铝富燃料推进剂配方为基础,通过改进推进剂的制备工艺制备了含镁铝富燃料推进剂。采用恒温式氧弹热量计测试了系统取样的含镁铝富燃料推进剂的热值;用方差和T检验法研究了镁铝富燃料推进剂热值的均匀性和稳定性,并对有关测试不确定度进行了分析。结果表明,含镁铝富燃料推进剂热值具有较好的均匀性和稳定性,扩展不确定度小于3.0(k=2)。Mg/Al fuel rich propellants were prepared by means of improving the craftwork based on the experimental formulation of Mg/Al fuel-rich solid propellants. The combustion heat of Mg/Al fuel-rich propellant, which was in system sampling, was determined by means of constant temperature oxygenic bomb calorimeter. The uniformity and stability of the results were studied by variance and student＇s T test method,and the uncertainties of the test were analyzed. The results show that the combustion heat of this sort of Mg/Al fuelrich propellants prepared had better uniformity and stability. Its extended uncertainty is less than 3.0 in case of k =2.
