FIELD: methods of production of armoring of solid fuel charges made out of a ballistite solid rocket propellants.
SUBSTANCE: the invention is pertaining to the field of production of armoring of solid fuel charges made out of ballistite solid rocket propellants. The method provides for application of the adhesive underlayer on a propellant grain, its placement in a mould and injection of the heated up to a yield state of the armoring composition in the clearance between the mould and the propellant grain. After solidification of the armoring composition the surface of the armoring coating is treated with a 3 % solution surfactant in an acetone with drying at the temperature of 15... 35°C during no less than 10 minutes, then apply by a dipping the surface screening film layer of a composition, which includes "Leikonat" adhesive (triphenylmethaneizocyonate) - 70 mass %, dibutylstannumacetate propionate - 0.2...0.4 ass %, acetone - the rest. The technical solution ensures a high manufacturability of manufacture of the charges with the reduced smoke formation.
EFFECT: the invention ensures a high manufacturability of manufacture of the charges with the reduced smoke formation.
