FIELD: spacecraft.
SUBSTANCE: proposed expulsion system with separation of liquid and gas for filling spacecraft at orbit contains pressurizing gas cylinders, pressure regulator, tank to be emptied with displacement diaphragm dividing the tank into liquid and gas spaces, transfer line with valve and tank to be with drain line. Propellant expansion compensator is installed additionally on transfer line between tank to be emptied and valve. Said compensator is made in form of reservoir with flexible separator of liquid and gas whose gas space is connected with gas space of tank to be emptied, and liquid space, with liquid space of said tank.
EFFECT: improved reliability of expulsion system, possibility of its operation after interruptions in spacecraft filling.
