METHOD OF MAKING COMPOSITE SOLID ROCKET PROPELLANT CHARGE Russian patent published in 2018 - IPC C06B21/00 C06D5/06 F02K9/24

Abstract RU 2660101 C1

FIELD: technological processes.

SUBSTANCE: invention relates to a method of manufacturing a charge of a rocket solid fuel mixture (RSFM) using a pressure injection molding or injection molding process at low pressure, which allows to produce small- and medium-sized products in a wide range of changes in the rheological characteristics of the fuel mixture in comparison with the values admissible for the technology of free molding. Method consist in mixing the initial components to produce a fuel mass in a planetary-type mixer, from the mobile bowl, the mass is squeezed out through a screw-type vacuum pressure device with the latter at the inlet of the latter chamber for evacuation with a spinneret and injected into the mold.

EFFECT: solution ensures that air inclusions do not enter the mold.
