For the problem of the composite solid propellant aging , the aging mechanism and the main aging influencing factors of the composite solid propellant are discussed .Based on a certain compos-ite solid propellant grain , accelerated aging experiment in high temperature condition are set up .By re-searching the storage stability of HTPB propellant under the high temperature and accelerated aging condi -tions, the changing rule of all storage stability following the aging time is gotten ,and the aging mechanism of HTPB propellant in high temperature and accelerated aging conditions is analysed , the life of HTPB propellant grain is estimated.
