METHOD FOR PRODUCTION OF SOLID-PROPELLANT CHARGES (MODIFICATIONS) Russian patent published in 2007 - IPC F02K9/24 C06B21/00 

FIELD: production of solid-propellant charges.

SUBSTANCE: the method for production of solid-propellant charges of the ballistite type, high-plasticized type inclusive, consists in molding of charge blanks, 30 to 200 mm in dia. At molding of the charge blanks mixing of the propellant components in a neutral medium, rolling of a propellant tablet, drying and molding on a conveyer press through a bell-shaped press tool by the flow-passage method are accomplished. After molding of blanks thin-composite charges of a low, up to 3 mm, outside diameter on vertical hydraulic presses of the general industrial destination are molded by the flow-passage method. According to the second modification, the method consists in mixing of the propellant components in a neutral medium, squeezing out, rolling of a propellant tablet, drying and molding by the blind method. Thin-composite charges of a low diameter are molded from the blanks molded by the blind method and heated to the temperature of thermoplastic deformation. Molding by the flow-passage method is accomplished on vertical hydraulic presses of the general industrial destination. According to the third modification, the method consists in molding of the propellant components by the blind method. Earlier produced propellant grains crushed to the dimensions of rolled tablets are used as a material for molding by the blind method. Thin-composite charges heated to the temperature of thermoplastic deformation are molded by the flow-passage method from the blanks molded by the blind method. Molding by the flow-passage method is accomplished on vertical hydraulic presses of the general industrial destination.

EFFECT: provided adaptability to streamlined manufacture, quality and productivity at production of thin-composite solid-propellant charges.
