ABSTRACT:
2. An article of manufacture useful as a gas generator and comprising a container having an outlet and supported and adapted to burn within said container and adhered to the walls of said container a mixed, shaped and cured composition of matter characterized by generating large volumes of gas on combustion and, except for minor amounts of compounding ingredients, consisting essentially of from about 70 to 87% by weight of finely-divided dried ammonium perchlorate, from about 0.5 to 5.0% by weight of at least one high surface area finely-divided essentially anhydrous inorganic silicon and oxygen-containing burning rate modifier selected from the group consisting of silicon monoxide, fume silica, arc silica and silicon oxyimide, and the balance a combustible organic elastomeric polymeric binder selected from the group consisting of a cured polyesterurethane of an organic diisocyanate and a hydroxyl terminated polyester of a dibasic acid and a glycol and a polymer comprising predominantly linear carbon chains cured through at least a portion of its combined curable acid groups selected from the class consisting of COOH, SO.sub.3 H, SO.sub.2 H and PO.sub.3 H.sub.2 radicals.
