Abstract
A method for producing porous propellant charges from a mixture containing a propellant and a filler is described wherein a propellant having a decomposition temperature above 200° C. is employed with a thermally removable filler to provide the charge forming mixture. The mixture is molded into a charge body and is subsequently heated to remove the filler at a temperature that is at least 50° C. below the decomposition temperature of the propellant. Due to the heating at the elevated temperature the filler is wholly or in part removed to form a cavity within the charge body.
