基于RAAD分析的民用飞机需求确认方法研究与应用

Research and application of civil aircraft requirement validation methodbased on RAAD analysis

摘要:

民用飞机需求确认过程是一款飞机研制和适航取证的重要过程之一，常见的民用飞机需求确认方法主要包括需求追溯、评审、分析、相似性、建模和试验等。现有民用飞机需求确认方法中缺少能够系统性表征需求来源、需求间关联关系，需求分解(分配)、需求分析与作用的方法。本文在已有民用飞机需求确认方法基础上，综合考虑需求系统性确认的相关要素，提出了基于需求分解(分配)分析(Requirements Allocation and Analysis Document, RAAD)的需求确认方法，并在民用飞机和系统研制中进行了应用。结果表明：该方法进一步确认了民用飞机需求的正确性和完整性，减少了民用飞机需求的迭代周期。

Abstract:

The requirement validation process of civil aircraft is one of the important process of an aircraft development and airworthiness certification. Common civil aircraft requirement validation methods mainly include requirement tracing, review, analysis, similarity, modeling and testing. The existing civil aircraft requirement validation methods cannot systematically characterize the sources of requirement, the correlation between requirement, requirement allocation, and the analysis and action of requirement. In this paper, based on the existing civil aircraft requirement validation methods and considering the relevant factors of systematic requirement validation, a requirement validation method based on Requirements Allocation and Analysis Document(RAAD) is proposed, and has been used in the development of civil aircraft and systems. The application results show that this method further confirms the correctness and completeness of civil aircraft requirements, and reduces the iterative cycle of civil aircraft requirements.
