MIXED SOLID ROCKET FUEL CHARGES MANUFACTURING METHOD Russian patent published in 2019 - IPC F02K9/24 C06B21/00 

FIELD: rocket equipment.

SUBSTANCE: invention relates to the mixed solid rocket fuel (MSRF) large-scale charges manufacturing method using the free casting method. According to the invention, the fuel mixture drain through a drain system into assembled with the channel-forming tool housing is performed using the additional autonomous tank, made in the form of a cylinder with a piston, draining the prepared in the mixer fuel mixture entire volume into it. Tank is joined to the drain system vertically with the piston location at the top of the tank. Installed in place of the mixer an autonomous additional tank is used for the housing volume filling above the channel-forming tool drain hole or for the housing entire volume filling.

EFFECT: method allows for body volume reliable filling with the fuel mixture above the channel-forming equipment drain hole, at that simultaneously minimize the fuel mixture remainder to be disposed of after its displacement from the autonomous additional tank.
