The specific purpose of a pyrotechnic mixture for a Gas Generator (GG) of Base Bleed (BB) projectile requires a carefully balanced combustion velocity for obtaining the maximum projectile range and avoiding a reactive propelling force. The development of the pyrotechnic element is done under laboratory conditions which often differ from the real usage conditions. To be able to fairly predict the combustion process characteristics in the real GGs of BB projectiles, some influential technological factors and their influence on the combustion velocity have been investigated. Factors which were observed to have the most significant influence on the combustion velocity of pyrotechnic compositions are charge density, oxygen balance, combustion chamber wall thickness and material type. Individual and combined influence of these factors on the combustion velocity will also be presented in this paper.
