초록

A process for preparing a porous propellant grain which comprises blending at least two combustible materials to form a homogeneous mixture, adding a predetermined amount of a liquid dispersant to said mixture to form a slurry, and flash drying the slurry in order to form a porous, single grain propellant having a greatly increased burning surface. A single grain propellant is produced having a flat, torroidal shape with a central cylindrical core and honeycombed with a plurality of porous channels extending entirely through the grain to increase the bur...

대표
청구항

A porous propellant grain wherein said grain has a plurality of randomly oriented, radial and longitudinally interconnected porous channels having a variety of diameters, extending entirely through said grain to increase the burning surface of said grain.
