Abstract

The invention relates to a manned spacecraft on-orbit replaceable unit identification method. The method comprises the following steps of S1, determining a manned spacecraft on-orbit maintenance strategy; S2, performing life analysis on the manned spacecraft, and determining an on-orbit maintenance project in combination with the on-orbit maintenance strategy; S3, analyzing the maintenance characteristics of the on-orbit maintenance project, and determining alternative units; S4, analyzing the influence of the alternative units during maintenance and replacement; and S5, screening out an on-orbit replaceable unit from the alternative units. Requirements and influences of the on-orbit maintenance unit on the aspects of safety, reliability, maintainability, testability, supportability and the like are comprehensively considered, so that the purposes of quickly and conveniently replacing the unit and reducing maintenance and guarantee resources on the basis of guaranteeing system safety are achieved.

Description

technical field [0001] The invention relates to a method for identifying an on-orbit replaceable unit of a manned spacecraft. Background technique [0002] During the long-term operation of a manned spacecraft, various failures may occur, seriously affecting mission completion and system safety. On-orbit maintenance is an effective means to prevent and eliminate failures and ensure the long life of manned spacecraft. For example, the original design life of the Mir space station is 5 years, but the actual life is extended to 15 years through on-orbit maintenance support (according to statistics, 75% of the working time of the astronauts on the station is used for on-orbit maintenance) and maintenance resource guarantee; the International Space Station A large number of maintenance operations have also been carried out on the space station. As of October 2005, the astronauts have carried out more than 4,000 hours of maintenance on the American module and the Russian module. ...
