Abstract

The combustion properties of NEPE propellant with 8% aluminum content were studied. It was observed that increasing the ratio of NG/DEGDN, decreasing the particle size of AP, and increasing contents of fine particle AP are effective measures to increase the burning rates of the propellant. Simultaneously, decreasing the particle size of HMX can reduce it's burning rate and pressure exponent. PbCO3 synthesized by ourselves can reduce the pressure exponent more than the bought one.
