Abstract
A pyrotechnic gas generant composition including a high oxygen balance fuel that is the resulting reaction product of an aminoguanidine or polyaminoguanidine salt and nitric acid, namely, aminoguanidine dinitrate, diaminoguanidine dinitrate, and triaminoguanidine dinitrate. Specifically, aminoguanidine dinitrate, diaminoguanidine dinitrate, and triaminoguanidine dinitrate can be used as monopropellants or in combination with oxidizers and additives as a solid bipropellant composition. In each instance, the high oxygen balance fuel(s) of the present invention provide(s) both high gas output and low production of solid combustion products. Specifically, the high oxygen balance fuel(s) may be incorporated into gas generators, gun propellants, inflation and expulsion devices, flotation devices, pyrotechnics, fire suppression devices and smokeless, reduced smoke and metallized rocket propellants.
