Abstract

A low-solids gas generating composition and a method of producing a gas. The gas is produced by combusting a mixture of a fuel selected from the group consisting of guanidine nitrate, nitroguanidine, cellulose, cellulose acetate, hexamine, 5 amino-tetrazole, 5 nitro-uracil, guanidine salt of 5 nitro-uracil, and mixtures thereof, an oxidizer selected from the group consisting of ceric ammonium nitrate, strontium nitrate, basic copper nitrate, a mixture of ammonium perchlorate and at least one alkali metal salt, and mixtures thereof, and a cupric oxalate hemi-hydrate coolant. The oxidizer-fuel mixture is within about 4 percent of stoichiometric balance, and the low-solids gas generating composition produces no more than about 0.082 cubic centimeters of solids per gram of gas generating composition on combustion.
