Abstract: For production of a propellant charge powder, especially for medium and large calibers, in a process in which the solid is incorporated together with a liquid in a mixing and drying process into the channels of a granular green material and compacted therein to form a plug, the solid, under otherwise identical process conditions, is set within a setting range of >0-0.5% by weight based on the weight of the granular green material. For more significant lowering of the maximum pressure within an upper temperature range and for more significant raising of the maximum pressure within a lower temperature range of the application temperature range, an increased amount of solid is used. The solid is a substance whose melting point is at least 10° C., especially 20° C., above a maximum use temperature of the propellant charge powder and which is inert toward the granular green material. Since the plug consists virtually exclusively of inert material, a high ballistic stability is achieved.

Abstract: The method for producing a propellant powder (TLP) with a layered grain structure starts with a green powder, which is impregnated in a watery emulsion with an energetic plasticizer and a polymeric deterrent. Propellant powders (TLP) can be produced in industrial quantities by avoiding the dangerous direct introduction of a blasting oil. The propellant powders (TLP) produced in this way have similar characteristics and a similar structure as the known propellant powders (TLP).

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.
