The invention provides a multilayer assembly of a satellite propulsion system. The multilayer assembly comprises first material layers and second material layers which are laid at intervals; the second material layers are removed at the grounding end parts and the overlapping end parts of the multilayer assembly to expose the first material layers; and the first material layers are in direct contact with the grounding end parts and the overlapping end parts of the multilayer assembly, and / or are connected through conductive parts. A simple grounding structure of the multilayer heat insulationassembly between the first material layers is realized, and the multilayer manufacturing and assembling process is simplified. The multilayer manufacturing and assembling process can be simplified, the problem that a long-strip-shaped pipeline multi-layer heat insulation assembly is not prone to being riveted with a grounding piece due to the shape is solved, the multilayer grounding process of the pipeline is simplified, it is guaranteed that the pipeline is fully and effectively grounded, and therefore the charging and discharging risks of the satellite propulsion system are effectively reduced.
Description
Technical field [0001] The invention relates to the field of aerospace technology, in particular to a multilayer component of a satellite propulsion system. Background technique [0002] The propulsion system is the actuator of the satellite attitude and orbit control sub-system. It is used to provide rate damping, maintain orbit, maintain attitude, adjust attitude and change orbit, etc. It is an extremely important part of the satellite. The propulsion system includes storage tanks, pipelines, pressure sensors, self-locking valves, addition and exhaust valves, solenoid valves, etc. In order to meet the needs of on-orbit flight, the temperature of the propulsion system needs to be controlled within a relatively high range, which requires various components Paste the heater on the top, and wrap the multi-layer heat insulation component on the outside to improve the heating efficiency and reduce the influence of the temperature of other single units in the cabin. [0003] In order t...
