METHOD OF FABRICATING SPACECRAFT THERMAL CONTROL SYSTEM LIQUID CIRCUIT Russian patent published in 2016 - IPC B64G1/50 G01M3/02

Abstract RU 2574104 C1

FIELD: aircraft engineering.

SUBSTANCE: invention relates to thermal control systems of, mainly, telecommunication satellites. Claimed process comprises the fabrication of manifolds and connecting tubes from special-profile tube with two flanges. Liquid paths of said manifolds and tubes are flushed with organic heat carrier, then, dried, subjected to strength and leak tests. Before said test, manifolds and tubes are heat cycled at ambient air temperature and held at minimum and maximum temperatures for at least 60 min. Said temperature is not lower than that of 95% of micro leak flushing fluid distillation. Every cycle (three or more) is terminated with compressed air blowing at maximum pressure and temperature.

EFFECT: higher reliability of tightness, hence, quality of liquid circuit fabrication.
