Public platform satellite chemical propulsion subsystem modular layout method

Abstract

Disclosed is a public platform satellite chemical propulsion subsystem modular layout method. To solve the problems that welding of valve bodies is completed on a satellite, once the valve bodies fail, it is necessary to remove a large amount of equipment on the satellite before welding again, and welding even cannot be performed in the later stage of manufacturing of the satellite; combination valve bodies of different functions are allocated together, when a failure is tested, the failure position cannot be accurately and timely judged and thus difficulty in troubleshooting is caused, the invention provides the public platform satellite chemical propulsion subsystem modular arrangement method. According to the invention, the method, in which the valve body combination is divided and a valve body module is determined according to the propulsion principle, is applicable to all satellite propulsion system layouts. By adopting the method in which the valve body module method is composedof the valve bodies, the valve bodies occupy a small space, the connection is simple, the module is welded not on the satellite, the entire module is installed on the satellite, and thus operation isconvenient. A gas pipeline module is positioned at a north partition of a propulsion cabin, an oxygen pipeline module and a combustion pipeline module are positioned at a middle partition of the propulsion cabin, the functions of the modules are clearly divided, and testing and troubleshooting are facilitated.

Description

technical field [0001] The invention relates to a modular layout method for a satellite chemical propulsion subsystem of a public platform. The invention belongs to the field of satellite design, and specifically relates to a modular layout method for a satellite chemical propulsion subsystem of a DFH-5 platform and similar public platforms. Background technique [0002] The layout of the chemical propulsion system of the existing satellite platform is not divided into valve body modules according to the propulsion principle. The valve bodies with different functions are arranged together, which takes up too much space on the deck; the welding of the valve body is completed on the satellite. It is necessary to dismantle a large number of equipment on the satellite before welding can be performed again, even in the later stage of satellite manufacturing. The valve bodies with different functions are arranged together. When a problem occurs in the test, it is impossible to accu...

AI Technical Summary

Problems solved by technology

It solves the problem that the chemical propulsion system of the existing satellite platform is arranged with different function combination valve bodies together, occupying too much space on the deck, reduces the layout space of the valve body, and improves the space utilization of the satellite; solves the problem that the valve body is welded on the satellite Completed, once there is a problem with the valve body, it is necessary to dismantle a large number of equipment on the star before welding again, and even the problem that it cannot be welded in the later stage of satellite manufacturing improves the maintainability of the valve body of the propulsion system

It solves the problem that different functional combination valve bodies are arranged together. When a problem occurs in the test, the problem location cannot be judged in time and accurately, which causes difficulties in troubleshooting, and the troubleshooting and maintenance efficiency of the propulsion system valve body is improved.
