METHOD FOR MAKING LIQUID CIRCUIT OF SPACECRAFT TEMPERATURE CONTROL SYSTEM Russian patent published in 2019 - IPC B64G1/50 G01M3/02 

FIELD: astronautics.

SUBSTANCE: invention relates to space engineering, particularly, to manufacturing of thermal control system. Method of manufacturing of liquid circuit of spacecraft thermal control system includes hydraulic connection of circuit with filling device; filling and washing with solvent; filling the circuit and pumping heat carrier. Filling device includes, in particular, pneumatic valves operating by commands from a personal computer. At that, on the section of one of the connecting pipelines near its hydraulic connector connected to the connecting pipeline going towards the liquid loop, a compensation device is installed, liquid and gas cavities of which are pre-filled with required amounts of heat carrier and gas. Fluid cavity of the compensation device includes a pipeline connected to it with a hydraulic connector on its free end, which is connected with hydraulic connector of connecting pipeline after immediate disconnection of hydraulic connectors of connecting pipelines from "Input" and "Output" of filling device at arbitrary blackout or hanging of personal computer or after uncontrolled change of pressure of heat carrier.

EFFECT: enabling higher reliability.
