Abstract: A review and discussion on burning rate temperature sensitivity of CMDB propellants is made in the paper. The burning rate temperature sensitivity of propellants can be decreased obviously, by means of filling nitramine and finegranular ammonium perchlorate in double-base propellants. It is the cause of the decrease that the fillers have better thermostabilily, moreover, they effect the physical structure and the che-modynamics properties of the propellants. The influece acts mainly in condensation phase in gas phase secondly.
