METHOD FOR MANUFACTURING SOLID-FUEL ROCKET ENGINE CHARGING FROM MIXED ROCKET FUEL Russian patent published in 2017 - IPC C06D5/06 C06B21/00 

FIELD: engines and pumps.

SUBSTANCE: method of manufacturing a charge from a mixed rocket fuel is carried out by vacuum thermal pressing of the powdered composition directly into the body of a solid-fuel jet engine. For this purpose, a powdered fuel mixture is placed in the engine casing, from the open side of the casing, a process cylinder temporarily placed, containing a carefully fitted piston with a gas outlet through which the air is removed from the fuel mixture. After pumping out the air, the body is heated, starting from the bottom and from the side surface. As the fuel mixture melts, the piston moves to the bottom, compressing the mixture until it completely turns into a melt. After the entire mixture is melted, the charge is cooled and the piston is removed.

EFFECT: method enables to simplify the technology of fuel preparation as much as possible, to significantly shorten the period of equipping the engine and to fill the solid fuel rocket with fuel at the launch site, which eliminates the need to transport a charged engine.
