Description

Technical Field

[0001] The invention belongs to the field of satellite design and relates to a satellite push pipeline system based on limited space. Background Art

[0002] Satellite chemical propulsion system is one of the main measures for low-Earth orbit satellite transfer orbit change, position maintenance during orbit operation and other tasks. With the increasing demand for satellite space utilization, 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 layout methods for determining the instruments and equipment of chemical propulsion systems at home and abroad vary with the available space on different satellite platforms. The patent [Satellite Propulsion Pipeline Layout Method, CN107264839B, Na Shunbuhe, Wang Xiaofeng, Yuan Wei, Wu Yiping, Xu Shenxin] reduces the impact of the side wall opening on the strength of the bearing tube, eliminates the process of disassembling the partition when welding the pipeline, and achieves the purpose of eliminating the bridge cable bracket to isolate the pipeline and cable, which can reduce weight and reduce operational risks. The layout of the chemical propulsion system of the DFH-4 platform has valve bodies with different functional combinations arranged together, which occupies too much space on the cabin board. According to the engineering requirements, the DFH-5 platform satellite invented a patent [A modular layout method for chemical propulsion subsystems of public platform satellites, CN108298111A, Xia Yongquan, Gao Xiuhui, Jiang Hao, Yang Wen, Fan Wei, Li Xuelin, and Zou Shuang], which divides the valve body combination according to the propulsion principle and determines the valve body module scheme. The valve body module method has a small space occupation, simple connection, and is easy to operate, which solves the problem that the existing satellite platform chemical propulsion system has valve bodies with different functional combinations arranged together, which occupies too much space on the cabin board.

[0004] With the development of a new generation of satellites, higher requirements have been put forward for the development of chemical propulsion pipeline layout in terms of available space. Especially for the DFH-3E satellite platform, in order to ensure the effective load ratio, the valve body and pipeline layout space is further reduced to 4 side panels and bearing cylinders under the premise that the chemical propulsion system is not reduced. In view of the above problems, the DFH-3E satellite platform must redesign the layout of pipelines and valve bodies to meet the needs of DFH-3E platform satellites. Summary of the invention
