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 with...
A method for producing a porous propellant charge which comprises mixing a plurality of particles of a high temperature-resistant propellant having a decomposition temperature above 200°C. with a plurality of particles of a thermally removable filler to form a mixture containing said propellant particles and said filler particles, said filler being a solid material at ambient temperature and being a distillable or sublimable material which is removable by the effect of heat at elevated temperature and the concentration of the filler particles in said mix...
