  • Process for preparing solid propellant grains using thermoplastic binders and product thereof
    Patent number: 4764316
    Abstract: Thermoplastic elastomer particulates, oxidizer particulates, fuel particulates, plasticizers and other propellant formulation ingredients are mixed to produce a dry blend. The dry blend is tightly packed into a rocket motor casing or mold. The dry blend is then heated in place, beginning at the bottom and continuing upward, to fuse the thermoplastic elastomer. During fusion, vacuum and mechanical compaction pressure are used to eliminate interstices. Upon cooling, a solid propellant grain is produced.
