Abstract: An organo-metallic ballistic modifier produced as an evaporation residue by he reaction of normal lead beta resorcylate and monobasic cupric salicylate in an aqueous solution of water or alcohol at an elevated temperature (180.degree. F - 220.degree. F). The modifier allows the use of a solvent or solvent/solventless process in the production of double base propellants exhibiting a mesa burning rate.

Abstract: Ballistic modifiers of up to one micron in size are slurried and mixed with high impulse propellant slurry in order to produce a high impulse propellant having a plateau or mesa burning characteristic.

Abstract: A novel ballistic modifier complex is produced by mixing and interacting an rganic isocyanate with lead beta resorcylate and cupric salicylate in an inert solvent. The complex product obtained after removal of the solvent, when incorporated into a nitrocellulose-nitroglycerine double base propellant, yields a propellant composition of excellent ballistic properties and improved stability against development of exudate which inhibits ignition.

Abstract: An organo-metallic ballistic modifier produced as an evaporation residue by the interaction of two or more organo-metallic salts in an aqueous solution of water or alcohol at an elevated temperature (180.degree. F - 220.degree. F). The modifier allows the use of a solvent or solvent/solventless process in the production of double base propellants exhibiting a mesa burning rate.

Abstract: In the preparation of double-base propellants where nitrocellulose-based granules are gelatinized by an explosive oil, the ballistic properties of the propellant are controlled by adjusting the content of nitrogen of the nitrocellulose of the granules, said content ranging from 12.6 to 14 % approximately.
