Abstract
The proposed propellant powder exhibits a temperature-independent burning behavior and high ballistic stability. The production process starts with a perforated bulk powder grain, which is processed inside a mixing apparatus with a solid material, a plug-stabilizing moderator or deterrent (if necessary also a radical initiator) and a low-viscous liquid. With a minimum amount of solid material, moderator or deterrent and liquid and because of the continuous mixing, the form function is influenced in such a way that the gas-formation rate is practically independent of the propellant powder temperature. As a result, the muzzle energy at the normal temperature and, above all, at a low deployment temperature can be increased markedly as compared to that of a standard propellant powder. With the propellant powder according to the invention, for which the grain has at least one perforation that discharges with an opening to the outside surface of the grain, wherein the opening is closed off with a plug, the plug has a temperature-dependent mobility. As a result, the plug has a higher mobility for a lower deployment temperature than for a higher deployment temperature, so that the plug permits a faster hole burning at a lower deployment temperature than at a higher deployment temperature.
