Abstract:
A stable chlorine-free solid rocket propellant composition containing a low energy binder component having an HEX value not exceeding about 0 cal/gm and comprising, in combination, a nitrate salt and/or phase stabilized nitrate salt as oxidizer component, a Mg/Al alloy of limited Mg content as a fuel component, at least one energetic plasticizer component, and a burn rate catalyst.
Abstract:
A tracer composition with a relatively high luminous output and a moderate burn rate includes from 35 to 47% by weight magnesium; from 40 to 53% by weight strontium nitrate, from 2 to 10% by weight magnesium carbonate, from 0 to 6% by weight color intensifier; from 0 to 6% by weight retardant and from 3 to 8% by weight of a synthetic polymer binder selected from the group consisting of (i) a terpolymer of vinylidene fluoride, hexafluoropropylene and polytetrafluoroethylene and (ii) a copolymer of vinylidene fluoride and hexafluoropropylene. The composition is produced by dry mixing all of the ingredients except the magnesium and binder, dissolving the binder in a solvent such as acetone, forming a homogeneous mixture of particulate magnesium and binder solution, adding a non-solvent such as hexane to the mixture to initiate precipitation of the binder, mixing the dry mixture with the magnesium/binder combination, and adding additional non-solvent to complete precipitation of the binder, and drying the mixture thus produced.
Abstract:
The present invention is a flare illuminant composition, useful in hand-held signals, which composition is environmentally friendly and economical, containing a commercially available, aromatic, high energy, amine-based organic compound, 5-aminotetrazole, in place of the conventional and toxic KClO4, or, for the known alternative to KClO4, expensive, strontium bis-(1-methyl-5-nitriminotetrazolate)monohydrate.
Abstract:
Perchlorate-free flare compositions are disclosed which, when burned, produce yellow smoke and flames. Methods of producing the compositions are also disclosed.
