研究了高能推进剂固体组份粒度及粒度级配对燃速和压强指数的影响．实验结果表明，采用合适的粒度级配方，能将文中的基础配方燃速在７ＭＰａ下由９．０８ｍｍ／ｓ调节到１３．０４ｍｍ／ｓ，压强指数由０．８３下降到０．６４． The effects of particle size and particle size distribution of high energy propellant on the burning rate and pressure index were studied. The experimental results show that with the appropriate particle size formula, the burning speed of the basic formula can be adjusted from 9.08mm / s to 13.04mm / s at 7MPa, and the pressure index decreases from 0.83 to 0.64.
