摘　　要：为研究不同端酯基聚叠氮缩水甘油醚作为增塑剂时对推进剂能量特征的影响,利用White最小自由能法原理对GAPE增塑的HTPE-PU推进剂配方进行能量特征计算。结果表明:理论比冲与特性速度随RDX含量变化曲线为抛物线型,存在最大值;推进剂的最大理论比冲和最大特性速度随增塑比的增加而增加;在增塑比相同的条件下,推进剂的最大理论比冲和最大特性速度均随GAPE中臂数的增加而下降。The effects of different GAPE used as plasticizer on propellant energy characteristics have been investigated by using White＇s Principle of Minimum Free Energy in calculation of the energy characteristics of HTPE-PU propellant ingredient plasticized by GAPE. Results show that the variation curves of the theoretical specific impulse and characteristic velocity of propellants are parabola with the increasing of RDX content, and there exists a maximum value. The theoretical specific impulse and characteristic velocity of propellants are increasing with the increase of GAPE content. The maximum theoretical specific impulse and characteristic velocity decrease with the increase of the arms of GAPE.
