Research on Construction Method of In-service Aircraft Configuration Data Model

Abstract

In order to establish the basic data architecture for aircraft in-service configuration management, ensuring efficient implementation of it, the characteristics of configuration change caused by various maintenance and support operation during the service phase of large civil aircraft were analyzed. On this basis, formal classification of in-service aircraft configuration data was carried out. Based on the product structure tree, the architecture of the aircraft configuration data was constructed. The in-service aircraft configuration data schema was defined. By introducing the idea of Skyline query, the configuration change information filtering method was designed and implemented. Finally, method validation was performed by the maintenance and support data of an airline company. The results show that, the automatic extraction of configuration change information is realized effectively, ensuring the full integration of the in-service aircraft configuration data schema and production and maintenance information management, and ensuring the real-time and consistency of in-service aircraft configuration data management.
