A composite propellant comprises, by weight: A. FROM 78 TO 92% OF AN OXIDIZING AGENT WHICH IS AT LEAST ONE OF ALKALI METAL, ALKALINE EARTH METAL AND AMMONIUM CHLORATES AND PERCHLORATES, B. FROM 7.9 TO 17.2% OF AN ORGANIC BINDER WHICH CONTAINS OXYGEN BUT NOT NITROGEN, AND C. FROM 0.1 TO 0.8% OF A CARBON-CONTAINING COMBUSTION REGULATOR. This composite propellant is useful as a gas generator for inflatable cushion protection devices because the gaseous combustion products are substantially free from toxic gases.
A composite propellant, which consists essentially of, by weight: a. about 80 to about 92 parts of potassium perchlorate, b. about 8.5 to about 17 parts of cellulose triacetate, c. about 0.15 to about 0.5 parts of acetylene black, d. about 0.5 to about 2 parts of aluminium powder, and e. about 1 to about 3 parts of a plasticiser, the ingredients being in such amounts that said propellant produces combustion gases free of nitrogen oxides and containing less than 0.05% of carbon monoxide.
