METHOD OF FILLING MULTISTAGE LAUNCH VEHICLE

摘要

FIELD: space engineering; filling launch vehicles with high-boiling components of propellant. SUBSTANCE: method consists in filling the tanks provided with common hydraulic system, autonomous check of level and discontinuance of filling procedure. In case of failure of level check system of one tank or one stage of launch vehicle, filling of emergency tank is effected through tank of other unit or other stage of launch vehicle which is used as metering reservoir at regular transfer by of common hydraulic system either system either by gravity or by forcing out by excessive pressure with vent and safety valves of all tanks closed. EFFECT: enhanced efficiency. 1 dwg
