Abstract

A method for producing a propellant powder in particular for medium and large calibers is disclosed. In said method in which the solid is incorporated into the ducts of a green grain along with a liquid in a mixing and drying process and is compacted therein to form a plug the amount of solid is adjusted to an adjustment range of >0  0.5 wt. % in relation to the weight of the green grain while the other conditions in the process remain the same. In order to more substantially lower the maximum pressure in an upper temperature range and more substantially increase the maximum pressure in a lower temperature range of the operating temperature range a greater amount of solid is used. The solid is a substance the melting point of which exceeds the maximum operating temperature of the propellant powder by at least 10 °C in particular by 20 °C and which is inert in relation to the green grain. The fact that the plug is made almost exclusively of inert material results in high ballistic stability.
