A propellant formulation employing an energetic plasticizer, a solid oxidizer, a crosslinking agent, a curing catalyst, a ballistic modifier, and an acrylate - acrylic acid prepolymer binder comprised of about 95 parts of an acrylate selected from petrin acrylate and 2,2′dinitropropyl acrylate and o
A propellant formulation employing an energetic plasticizer, a solid oxidizer, a crosslinking agent, a curing catalyst, a ballistic modifier, and an acrylate - acrylic acid prepolymer binder comprised of about 95 parts of an acrylate selected from petrin acrylate and 2,2′dinitropropyl acrylate and of about 5 parts of acrylic acid has a low signature (i.e., propellants whose exhaust does not cause serious attenuation of visible, infrared, or radar radiation) while retaining the preferred specific impulse, mechanical properties, processing properties, and other properties of importance in solid propellants. The acrylate-acrylic acid prepolymer serves as the binder for a propellant comprised of an energetic plasticizer selected from butanetriol trinitrate (BTTN), glyceryl trinitrate (NG), and the mixed plasticizers of triethyleneglycol dinitrate (TEGDN), and trimethylolpropane trinitrate (TMETN), a solid oxidizer selected from cyclotetramethylenetetranitramine (HMX), cyclotrimethylenetrinitramine (RDX), and ammonium nitrate, a crosslinking agent, ballistic modifier, and curing catalyst.

A solid propellant composition that yields a high specific impulse and exhaust products that are substantially smokeless and with a low-signature, said propellant composition consisting essentially of: a prepolymer binder formulated of about 90-95 parts of an acrylate selected from petrin acrylate and 2,2′dinitropropyl acrylate and acrylic acid from about 5-10 parts, said binder employed in said composition in amounts from about 15-20 weight percent; a plasticizer selected from butanetroil trinitrate, glyceryl trinitrate, and the mixed plasticizers of triethyleneglycol dinitrate (TEGDN) and trimethylolpropane trinitrate (TMETN) in amounts from about 25-30 weight percent, said mixed plasticizers being in ratio of about 1 part TEGDN with 2 parts of TMETN; a solid oxidizer selected from cyclotetramethylenetetranitramine, cyclotrimethylenetrinitramine, and ammonium nitrate in amounts from about 50-60 weight percent; a crosslinking agent in an amount from about 1 to about 2.5 weight percent; a curing catalyst in an amount from about 0.1 to about 0.3 weight percent; and a ballistic agent in an amount from about 0.5 to about 1.5 weight percent.
