Abstract

The invention provides a high-orbit satellite assembly method based on bipropellant unified propulsion system, the method is divided into star structure assembly, propulsion product welding and thermal control product assembly, in which star structure assembly and propulsion product welding are divided into two stages I and II. According to star structure assembly stage I, propulsion product welding stage I, star structure assembly stage II and propulsion product welding stage II are implemented sequentially. Thermal control products include propulsion thermal control products and star structure thermal control products, according to the principle of irreversible process in the entire assembly process interspersed implementation. The process of the invention is conducive to improving theassembly efficiency and ensuring the assembly accuracy and product quality. Through engineering practice, the invention has the advantages of good coordination of the general assembly flow, high general assembly efficiency, strong guarantee of product installation accuracy and redundant control.

Description

technical field [0001] The invention relates to a satellite general assembly process, which is based on the general assembly of a high-orbit satellite platform and is suitable for the process of a satellite based on a dual-component unified propulsion system. Background technique [0002] The satellite dual-component unified propulsion system has a large number of supporting products, the layout of the propulsion components is compact, and the connecting pipelines between the components are densely interspersed in the star structure, which makes the final assembly process of the three systems of structure, thermal control and propulsion affect each other , It is impossible to realize the complete independence of the final assembly of each process. Contents of the invention [0003] In view of the defects in the prior art, the purpose of the present invention is to provide a high-orbit satellite assembly method based on a dual-component unified propulsion system, which can ...
