The present invention is directed to a propellant composition made from a lacquer, the lacquer comprising: (a) from about 15 to about 70 wt % of an organic solvent; (b) from about 0.1 to about 2.5 wt % of a stabilizer; (c) optionally, from about 0% to about 40 wt % of an energetic plasticizer; (d) optionally, from about 0 to about 10 wt % of a nonenergetic plasticizer; (e) optionally, from about 0 to about 10 wt % water; (f) optionally, from about 0 to about 15 wt % of additional additives; and balance being nitrocellulose; all weight percents based on t...


1. A method for manufacturing perforated propellant grains, comprising the steps of:extruding a propellant lacquer through an extrusion die assembly to form one or more propellant lacquer strands, said extrusion die assembly having a plurality of holes, each of said holes having at least one pin tip positioned therein, said propellant lacquer comprising: (a) from about 15 to about 70 wt % of an organic solvent; (b) from about 0.1 to about 2.5 wt % of a stabilizer; (c) optionally, from about 0 % to about 40 wt % of an energetic plasticizer; (d) optionally...
