More Information
Summary:The invention provides a space engine pre-cooling system, a working method and a spacecraft. The space engine pre-cooling system comprises a storage tank, an engine, a heat exchange loop heat exchange section and a double-layer transmission pipe. The heat exchange loop heat exchange section is arranged on the peripheral side of the engine; the storage box is communicated with the head of the engine through a double-layer transmission pipe; a loop is arranged between the heat exchange section of the heat exchange loop and the storage box, and the loop flows in a one-way mode, is led out from an interlayer of the double-layer transmission pipe, flows to an engine for heat exchange and then flows back to the storage box; the temperature maintaining device is used for maintaining the temperature of the engine of the space low-temperature propelling system, closed-loop driving is formed through the capillary action and heat exchange steam pressure, and low-temperature propellants are not wasted. 本发明提供了一种空间发动机预冷系统、
