Spacecraft configuration capable of being assembled and expanded on orbit

Abstract

The invention relates to a spacecraft configuration capable of being assembled and expanded on orbit, and belongs to the technical field of spacecraft configurations. The spacecraft configuration comprises a mother platform, a truss extension module, a first function extension module and a second function extension module. The mother platform is used for providing a power supply and propulsion power for on-orbit flight of the spacecraft, performing attitude and orbit control on the spacecraft and performing measurement and control communication with ground monitoring equipment; the truss extension module is used for mechanical, power and information connection of the mother platform and the first function extension module; the first function extension module is of a truss type main force bearing structure, structural plates with equipment interfaces are arranged in other directions except the direction where the first function extension module is connected with other modules, the equipment interfaces in the structural plates are used for externally hanging functional equipment, and mechanical, power and information connection between the functional equipment and the first functionextension module is achieved. According to the invention, module function requirements under different assembling expansion task requirements are realized, and the spacecraft configuration has good acceptable on-orbit service capability.

Description

technical field [0001] The invention belongs to the technical field of spacecraft configuration, and specifically designs a spacecraft configuration that is applicable to on-orbit expandable, reconfigurable and acceptable services. Background technique [0002] The core of the field of spacecraft on-orbit servicing technology is on-orbit assembly. Traditional spacecraft are subject to the constraints of the launch vehicle, and they all need to go through strict configuration and layout design, so as to maximize the efficiency of the spacecraft under the conditions of large systems such as the given delivery envelope and launch weight. In short, that is, to load more loads and equipment. With the continuous development of spacecraft on-orbit service technology, more load mounting surfaces can be provided through multiple on-orbit assembly, so as to completely solve the fundamental problem of limited spacecraft efficiency caused by one launch. At the same time, for the parti...
