Abstract
Liquid gas generant compositions are aqueous solutions of hydroxylammonium nitrate as the oxidizer and a fuel selected from the group consisting of nitrate salts of amines of the formulae: PA1 A.sup.1) an amino tetrazole or amino triazole, PA1 A.sup.2) an amine of the formulae (I) (NHZ).sub.2 --C.dbd.O, (II) (NHZ).sub.2 --C.dbd.NZ, (III) HN--(CO--NHZ).sub.2, where the Zs are the same or different and are selected from H and NH.sub.2, PA1 A.sup.3) C.sub.2 -C.sub.3 -alkyldiamine, and mixtures of the nitrate salts of amines of the above formulae.
