Research on Aircraft System Architecture Modeling Method and Structured Data General Management Based on SysML

With the increasing complexity of aircraft, document-based systems engineering has gradually become inadequate, and model-based systems engineering has become a hot issue in the aviation industry and academia. In view of the characteristics of aircraft architecture design, this paper proposes a system architecture model modeling method and structured data management method based on SysML (System Modeling Language). Firstly, the definition and classification of complex system architecture design are introduced. Then, combined with the development characteristics and process of civil aircraft, an architecture model design method and a general data management structure based on SysML are proposed, and the effectiveness and feasibility of the method are verified by taking an aircraft electrical power system as an example, which provides a reference for data management and modeling analysis of civil aircraft or other complex system architecture models.
