FIELD: means of loading by high-density gases mainly of capacities of power units of space vehicles.
SUBSTANCE: the offered method consists in maintaining of pressure in the tank being loaded at which xenon overflows from the filling tank to the tank being loaded. After balancing of pressures in the filling tank and in the tank being loaded topping-up is performed at a temperature below the critical one in the transfer conditions with monitoring of the topping dose. Prior to installation of the tank to be loaded on the space vehicle, liquefied xenon is brought to the gaseous state by heating. Two check valves are installed in succession in the offered device in the loading line, a pressure accumulator is positioned between these valves. The gas accumulator is made in the form of a vessel separated into two cavities by a membrane. One of the cavities is linked with the pressure source, and the other - with the loading line between the mentioned check valves.
EFFECT: enhanced quality of loading due to a more tight filling of the tank being loaded, preserved fuel in case of cancellation of space vehicle starting, which results in a reduced cost of starting.
