Up to the present all theories, that were described by the parameter including some unknown variables, were not able to express explicitly the acceleration sensitivity of the buring rate of solid propellants. This analysis containing the formation mechanism of a pit can predict unmerically the effects of aluminum content, the mass median diameter and the variance of aluminum particle size distribution. Furthemore, using slab motors, we carried out our tests for ten kinds of composite propellants with acceleration loads(0～350g) directed normal into the combustion surface, and the experimental results were compared with the analytical ones. The increasing aluminum particle size is likely to induce the more sensitive burning rate, but the effect of the aluminum content do not show the general character for the burning rate augmentation. The acceleration sensitivity of the burning rate would rather depend strongly upon the static burning rate, and it should be noticed that the pressure dependence of the burning rate augmentation for the composite propellants is completely opposite to that for the CMDB propellants.
