1. A low-solids gas generating composition, comprising a mixture of a fuel selected from the group consisting of cellulose, cellulose acetate, hexamine, and mixtures thereof, and an oxidizer comprising a mixture of ammonium perchlorate and at least one alkali metal salt, wherein the alkali metal salt produces an oxide upon combustion that reacts with hydrogen chloride to form an alkali metal chloride, and is present in an amount sufficient to scavenge any hydrogen chloride produced by the ammonium perchlorate during combustion, the ammonium perchlorate/alkali metal salt oxidizer and fuel are present in amounts in the oxidizer-fuel mixture, such that the ammonium perchlorate/alkali metal salt oxidizer and the fuel of cellulose, cellulose acetate, hexamine, or mixture thereof in the mixture are within about 4 percent of stoichiometric balance for a reaction between the ammonium perchlorate/alkali metal salt oxidizer and fuel, and the low-solids gas generating composition produces no more than about 30 percent solids on combustion.
