FIELD: transport.
SUBSTANCE: invention relates to space technology and may be used for stabilisation of preset engine thrust by correction of spaceship motion. Tank with working medium (WMT) has three chambers. All supercharge gas (SG) is kept in extra permanent-volume tank (EPVT) adjoining WMT wall opposite the bellows. In case current and preset fuel pressures differ, defined are valid current SG temperature and pressure between bellows and EPVN, fuel mass residue, current SG volume, SG portion of EPVT required to reach operating pressure proceeding from current pressure in EPVT and interchamber channel cross-section, as well as duration of transfer of this portion into central chamber. Interchamber valves are opened and closed at preset time.
EFFECT: increased and stable thrust, accurate computation of correction parameters.
