Abstract: A solid fuel for generating H.sub.2 or D.sub.2 gases, comprising magnesium orohydride diammoniate (MBDA) or its deuterated analog as the H.sub.2 or D.sub.2 source, an oxidizer selected from LiNO.sub.3 and KNO.sub.3, and a binder of polytetrafluoroethylene is a thermally stable gas generator composition which yields greater than 12.5 weight percent H.sub.2 or D.sub.2. The MBDA weight percentages by weight ranges from 80-90, the oxidizer ranges from 5-15, and the binder ranges from 2-15.

Abstract: A solid propellant gas generator for producing greater than 50-weight percent pure nitrogen gas comprising a stoichiometric blend of sodium azide, NaN.sub.3, and sodium sulfate, Na.sub.2 SO.sub.4, and ballistic modifiers.

Abstract: Solid reactant hydrogen gas generator formulations which yield greater than 5 weight percent hydrogen of greater than 98 mole percent hydrogen purity are formulated of a primary heat and hydrogen source selected from ammonia borane from about 50 to about 70 weight percent and hydrazine bisborane from about 0-30.00 weight percent, a first hydrogen-containing compound that functions as an auxiliary heat and hydrogen source consisting of ammonium nitrate from about 10.20 to about 17.82 weight percent, and a second hydrogen-containing compound that functions as an auxiliary heat and hydrogen source consisting of (NH.sub.4).sub.2 B.sub.10 H.sub.10 from about 9.80 to about 17.18 weight percent.

Abstract: An energetic liquid monopropellant comprising a mixture of bis (2,2-dinitropropyl) acetal; bis (2,2-dinitropropyl) formal; and bis (2,2,2-fluorodinitroethyl) formal.
