FIELD: aviation.
SUBSTANCE: according to the invention the liquid loop of the thermal control system for ground tests is charged with liquid heating medium, in particular solvent. Then the heating medium is drained by air purging till its complete removal prior to vacuum drying. The later precedes the thermal control system charging with actual heating medium. At that initially the entire liquid line is purged bypassing (by means of the bypass line control valve) the specified vertical heads of the radiator panels. These headers are purged after all the others (switching the control valve to another position).
EFFECT: increased produceability of the thermal control system and reducing time of purging during the heating medium drainage.
