Satellite pipeline pushing system based on limited space

Abstract

The invention relates to a satellite pipeline pushing system based on a limited space, and belongs to the field of satellite design. Gas outlets of the helium tank The1 and the helium tank The2 are both communicated with the gas path module; the gas circuit module is respectively communicated with the oxidant storage box MON-1, the combustion agent storage box MMH-1 and the combustion agent storage box MMH-2; the oxidant storage box MON-1 is communicated with the oxygen path module; the combustion agent storage box MMH-1 and the combustion agent storage box MMH-2 are both communicated with the combustion path module; the oxygen path module is respectively communicated with an external thruster A1, an external thruster A2, an external thruster A3, an external thruster A4 and an external engine ENGINE; the fuel path module is communicated with an external thruster B1, an external thruster B2, an external thruster B3, an external thruster B4 and an external engine ENGINE; the method is suitable for GEO satellite limited space pipeline layout, the space use efficiency on the satellite is improved, and therefore the pipeline layout space is reduced, and the pipeline length is reduced.

Description

technical field [0001] The invention belongs to the field of satellite design, and relates to a satellite-based push-pipe system based on limited space. Background technique [0002] The satellite chemical propulsion system is one of the main measures for the current low-Earth orbit satellite transfer orbit change, position maintenance during orbit operation and other tasks. With the improvement of satellite space utilization requirements, the efficient layout method of instruments and equipment such as pipes and valves belonging to the chemical propulsion system has become a crucial link. [0003] At present, the methods for determining the layout of chemical propulsion system instruments and equipment at home and abroad vary with the available space of different satellite platforms.
