Abstract: In order to study the effect of Al on the curing process of glycidyl azide polymer (GAP) spherical propellant, the curing kinetics of GAP spherical propellant is studied by rheotogical isothermal measurement. Cuing parameters are obtained through Sestak-Berggren model, and the curing models of GAP spherical propellants with 0% Al and 10% Al are established. The results show that the apparent activation energy of GAP spherical propellant during cuing is less changed in the range of 0
