METHOD OF MAKING ARTICLES FROM MIXED SOLID ROCKET FUEL Russian patent published in 2010 - IPC C06B21/00 C06D5/06 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of making articles from mixed solid rocket fuel. The method of making articles from mixed solid rocket fuel involves moulding articles into a case through pressure moulding of fuel mass on a continuously running installation with auger unloading, holding the moulded articles under pressure during operation of the auger with simultaneous cooling of the fuel mass in the auger by feeding a heat carrier into the housing of the auger, cutting off the fuel mass in the case using a cutter and press curing. Cooling of fuel mass in the auger feeding heat carrier into the housing of the auger begins 3-20 minutes before the end of moulding the article. After ageing of the moulded article, pressure in the case of the article is established in accordance with a mathematical formula by smoothly varying rotational speed of the auger. Further, without changing the rotational speed of the auger, the cutter is closed and after 0.5-1.0 minutes, rotational speed of the auger is smoothly reduced to zero and the auger is switched off. The stroke speed of the piston of the cutter during its closure is preset at a value not greater than 0.15 m/min.

EFFECT: design of a safe method of making quality monolithic articles from mixed solid rocket fuel.
