大型载人航天器试验覆盖性分析方法

A method for test coverage analysis of large manned spacecraft

航天器试验覆盖性分析,即开展试验项目对航天器设计的覆盖程度的分析,是航天器研制阶段至关重要的环节。文章提出了一种针对大型载人航天器的试验覆盖性分析方法,从分析层级、特性分析、工作模式、任务阶段4个维度,以及工程总体对大型载人航天器的技术要求、大系统接口控制要求、大型载人航天器各舱段的功能要求、飞行事件规划等多层次,开展大型载人航天器的试验覆盖性分析工作,通过逐条分解细化各项技术要求,最终得出系统验证规划矩阵。通过应用多维度多层次的试验覆盖性分析方法,不仅可以实现试验验证项目对大型载人航天器设计的全面覆盖,也可以对现阶段设计工作的全面性进行复核复查。

The test coverage analysis of a spacecraft,that is,the degree of the coverage for the spacecraft design in terms of test items,is an essential step in the spacecraft development.A method for the test coverage analysis of the large manned spacecraft is proposed in this paper.With this method,the test coverage analysis of a large manned spacecraft is carried out from the following four aspects,namely,the hierarchy,the characteristics,the work mode and the mission stage,and in various levels,such as the technical requirements to the large manned spacecraft in view of the overall project,the requirements of the large system interface control,the functional requirements of each module of the large human spacecraft,as well as the flight mission planning.The technical requirements are broken down into items,to form the planning matrix for the system validation.Through the above multi-dimensional and multi-level test coverage analysis,the desired coverage of the test verification project for the large manned spacecraft design can be achieved,and the comprehensive review of the design work at the present stage can also be made.
