Abstract
The objectives of this paper are twofold. The first objective is to better define the theoretical burning rate augmentation of solid propellants in the acceleration by using the presented fundamental concept on the pitting of the combustion surface and the agglomeration of metal at the bottom of a pit, particularly the dependence upon the aluminum content and its distribution is investigated.
The second objective is lo show the comparison of the calculated results with the experimental ones of the CMDB (Composite Modified Double-Base) propellants at acceleration levels from 0 g to 350 g.
