摘　　要：通过对三氢化铝应用于固体推进剂中的能量性能进行理论计算,得到了不同配方的三氢化铝推进剂的燃烧室平衡温度、比冲、特征速度、等压比热容等计算结果。分析结果表明,在固体推进剂中将金属铝替换为三氢化铝后,可以降低燃烧室的平衡温度和燃烧产物的凝聚相质量分数,增加燃烧产物的等压比热容和等容比热容,提高燃料的特征速度和比冲。By theoretically calculating the energy performance of aluminum trihydride applied in solid propellants,the calculation results including balance temperature of combustion chamber, impulse, characteristic velocity, specific heat under constant pressure etc. of aluminum trihydride-based propellants with different formulations were obtained. The analysis results show that aluminum trihydride replacing metal aluminum in solid propellants can decrease the balance temperature of combustion chamber and the condensed phase mass fraction of the combustion products, in- crease the specific heat capacity under constant pressure and specific heat capacity under constant volume of the com- bustion products, and increase the characteristic velocity and impulse of the fuels.
