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.

Composition pyrotechnique génératrice de gaz de propulsion qui contient un combustible à forte teneur en oxygène, lequel est le produit de réaction d'un sel d'aminoguanidine ou de polyaminoguanidine et d'acide nitrique, à savoir, le dinitrate d'aminoguanidine, le dinitrate de diaminoguanidine et le dinitrate de triaminoguanidine. Plus précisément, le dinitrate d'aminoguanidine, le dinitrate de diaminoguanidine et le dinitrate de triaminoguanidine peuvent être utilisés comme monergols ou en association avec des comburants et des additifs, et comme composition à diergols forts. Dans chaque cas, le ou les combustible(s) à forte teneur en oxygène de cette invention fournit(-nissent) un débit de gaz important ainsi qu'une faible production de combustibles solides. Plus précisément, le(s) combustible(s) à forte teneur en oxygène peut(-vent) être incorporé(s) à des générateurs de gaz, à des poudres à canon, à des dispositifs de gonflage et d'expulsion, à des dispositifs flottants, à des compositions pyrotechniques, à des extincteurs et à des propergols de fusée sans fumée, à fumée réduite ou métallisés.
