METHOD OF PREPARING CHARGE OF BALLISTITE SOLID ROCKET FUEL Russian patent published in 2008 - IPC C06B21/00 C06B25/24 C06D5/00 

FIELD: heating, fuel.

SUBSTANCE: invention relates to the field of manufacturing charges from ballistite solid rocket fuel (BSRF). The method preparing the charge of from BSRF on the basis of nitrocellulose and nitroglycerine is provides, includes the mixture of the components of BSRF in an aqueous medium with the obtaining of fuel mass, squeezing-out of the fuel mass, rolling - pelletisation, drying of the tablets, homogenisation and pressing of the charge using the feed-through method through the bell-shaped moulding-tool. In the method nitrocellulose is used with viscosity not less than 2.1°E, alkalinity of no more than 0.03% with the relation of nitroglycerine/nitrocellulose 0.6...0.7. Squeezing, rolling-pelletisation, drying, homogenisation and pressing are conducted with the maintenance of specific values of.

EFFECT: increase of physical and chemical stability of the charges from BSRF.
