MOBILE MIXER OF COMPONENTS OF MIXED ROCKET SOLID FUEL OF GRAVITATIONAL TYPE Russian patent published in 2018 - IPC B01F9/02 B01F15/00 

FIELD: rocket equipment.

SUBSTANCE: invention relates to rocket technology, namely, devices for the preparation of a composite solid rocket fuel (CSRF) used in technology of free casting into casing with the charge, simultaneously performing the functions of a gravitational-type mixer and a mobile container. Gravitational-type mobile mixer includes housing, frame on which casing and equipment for mixer operation and transport cart are mounted. Frame is equipped with brackets, on the horizontal platform of each of which is fixed a hydraulic cylinder for raising-lowering the frame, guides for placing the liner in the transport position, on the reverse side of the horizontal platform of each bracket are fixed guides for placing the liner in the working position. Transport trolley is equipped with brackets, on the horizontal platform of each of which a weight measuring device is mounted in form of strain gauge, equipped with a weight transfer element on the sensor, and supporting element, made allowing contact with hydraulic cylinder when lifting frame before weighing the mixer.

EFFECT: mixer provides significant reduction in the loss of fuel mass to be utilized by minimizing the amount of its required residue in the mixer to ensure the charge casing is filled by reducing error of the weight measuring operations.
