Abstract: During the manufacture process of the grain in solid rocket motor, the manufacture technique is able to affect its burning rate. Based on the development of the solid rocket motor of a missile, the effect of two manufacturing techniques of grain on the burning rate was analyzed using mathematical statistical method. The result shows that the average burning rates of two manufacturing techniques at -40℃have obvious difference.
