Abstract:
A minimum signature propellant formulation containing conductive polymers and having improved propellant insensitivity-impact and friction-properties, said minimum signature propellant formulation comprising in weight percent amounts of ingredients as follows:i. an energetic nitramine polymer from about 6.00 to about 7.00; ii. a plasticizer selected from butanetriol trinitrate plasticizer of about 19.61 and trimethyolethane trinitrate plasticizer of about 8.41; iii. carbon black in an amount from about 0.25 to about 0.50; iv. an oxidizer blend of ammonium nitrate of about 10.00, and an oxidizer selected from tetramethylene tetranitramine, and trimethylene trinitramine of about 47.50; v. conductive polymers selected from a copolymer of quaternary acrylate salt and acrylamide and polyaniline emeraldine salt of about 0.25 to about 0.50; vi. ballistic-modifiers selected from bismuth &bgr;-resorcylate and zirconium carbide; of about 1.0 to about 4.50; vii. a triisocyanate curing agent of about 1.73; and, viii. N-methyl paranitroaniline-chemical aging stabilizer of about 0.50.
