METHOD OF TESTING SPACE VEHICLE TEMPERATURE-CONTROL SYSTEM Russian patent published in 1999 - IPC

Abstract RU 2132805 C1

FIELD: space engineering; surface tests of space vehicle temperature-control systems. SUBSTANCE: in preparing the space vehicle for launch, temperature-control system is checked for functioning; then liquid passages of system and detachable equipment are disconnected and detachable equipment is removed from vehicle, after which volume of gas cavity of volume compensator is measured by means of standard reservoir. This volume is measured at two different permissible pressure before disconnecting the liquid passages (difference in magnitudes shall not exceed the limit preset at Manufacturing plant); after disconnection of these passages, volume of above-mentioned gas cavity is measured and volume of gas bubbles in liquid passage of system is determined also at two different pressure in gas cavity; volume of gas bubbles shall not exceed permissible limit. EFFECT: enhanced reliability of test results and enhanced operational reliability of temperature-control system. 1 dwg
