The loading parameters influencing ballistic behaviors of low temperature sensitivity charge are theoretically analyzed. The effect of mixed proportion of the propellant main charge to nitroguanidine-coated charge,burning surface ratio,SM/SB,and the burning surface temperature coefficient on the ballistic temperature sensitivity of the propellant are discussed in detail. The results show that increasing the percentage of coated propellant, decreasing burning surface ratio between the main charge and coated propellant charge and increasing the absolute value of burning surface temperature coefficient under some conditions are beneficial to reduce the ballistic temperature coefficient of LTSC.
