FIELD: engines and pumps.
SUBSTANCE: invention relates to development and operation of fuel store-and-feed systems of spacecrafts. The fuel tank supercharging system incorporates high-pressure cylinders communicating, via pneumatic lines, with the fuel and oxidiser tank gas chambers and throttling devices, shut-off valves, gas reducers and safety valves communicating with a momentless device. It incorporates additionally a heater representing a multi-circuit heat exchanger connected to the onboard thermal control system, every circuit of which is connected to an appropriate pneumatic line downstream of the throttling device arranged at the high-pressure cylinder. Note here that the heater is furnished with additional heat exchange circuits representing coils arranged in the heat exchanger casing, the aforesaid additional circuits being connected to the appropriate pneumatic lines upstream of the said safety valves.
EFFECT: higher safety and reliability.
