Abstract: In order to conduct effective management on aero-engine maintenance data, according to multi-dimensional and evolutionary characteristics of aero-engine maintenance data, it was divided into configuration data, object-related data and class-related data. With the introduction of concepts of aero-engine physical state and module physical state, an aero-engine configuration data management model was proposed so that the configuration data redundancy problem was solved. Aiming at the problem that aero-engine Service Bulletin(SB) states were difficult to control, a major part-centric SB state control model was put forward. After analyzing aero-engine lifecycle, an aero-engine maintenance data organization model was constructed to effectively organize aero-engine maintenance data. The proposed models were applied in a web-based aero-engine maintenance data management prototype system, and a large airline company had a trial. The trial result showed that the proposed models were effective and could satisfy airline requirements.
