Abstract: In this paper,the impact of various burning rate moderators, oxidizer particle size and its distribution, and the spin of the rocket motor on the performance of low burning rate propellant is discussed, A new type of coating agent for improving the measurement accuracy of burning rate is also presented. A steady low burning rate composite solid propellant has been developed,which has low pressure exponent and high accuracy of burning rate. The results show that the high spih speed of rocket motor (2400r/min) have an effect on the burning rate and the specific impulse of solid propellant.
