On-orbit assembly spacecraft based on pre-integrated truss

Abstract

The invention discloses an on-orbit assembly spacecraft based on a pre-integrated truss, and relates to the technical field of spacecraft on-orbit service. The on-orbit assembly spacecraft comprises apre-integrated truss structure, four solar battery arrays, a storage battery pack, two propelling modules, a pose measurement and control module and a digital management module; the pre-integrated truss structure is of a support structure with a Chinese character "jing" shape which is formed by four supports; the four solar battery arrays are symmetrically installed at the two ends of two opposite supports of the pre-integrated truss structure; the storage battery pack is installed on the outer side wall of one support of the pre-integrated truss structure; the pose measurement and controlling module is installed on the outer side wall of the support, which is opposite to the storage battery pack, of the pre-integrated truss structure; the two propelling modules are symmetrically installed on the outer side walls of the other two opposite supports of the pre-integrated truss structure; and the digital management module is installed on the inner side wall of one support of the pre-integrated truss structure. The on-orbit assembly spacecraft provides a novel means for on-orbit application of a large spacecraft, and can implement tasks such as on-orbit assembly and on-orbit functionexpansion.

Description

technical field [0001] The invention relates to the technical field of on-orbit service of spacecraft, in particular to an on-orbit assembling spacecraft based on a pre-integrated truss. Background technique [0002] Most of the current spacecraft are designed and assembled on the ground and launched into orbit to perform tasks. However, with the development of spacecraft technology, the requirements for the size and weight of spacecraft are getting higher and higher. Most of the current spacecraft are composed of multiple compartments or modules, and the size and weight are getting larger and larger. The total size of these spacecraft has far exceeded the launch capacity of the launch vehicle. Execution of on-orbit missions for large spacecraft. It is a good way to solve the series of problems by launching the spacecraft components into the orbit multiple times through the launch vehicle and implementing the assembly of the spacecraft on orbit. [0003] At the same time,...

Problems solved by technology

However, the on-orbit assembly of ISS still has the following shortcomings: the structural units assembled on-orbit are too complex, such as various types of trusses, which make the versatility not strong, which brings a lot of inconvenience to design, operation and even later maintenance. place; on-orbit assembly is often attended by people, which brings safety issues
