【Abstract】 The principle and method of the allowances control of composite solid propellant burins rate are researched. The effects of solid particle she deviation and ingnedieut weighing deristion on the burning rate allowances of moderate buning rate HTPB propellant are evacuated. The results show that the variation of burning rate is mainly due to the particle size deviation, and the effect of welshing deviation can be neglected.更多还原
