In order to solve the digitalized management problem of aero-engine in the whole lifecycle, a framework of aero-engine AMRO supporting system is put forward. Management of assembly, maintenance, repair and overhaul are involved. Modeling and integration of aero-engine status data, assembly process management, on-spot operation guide, online education support, integration and synchronization of data and fault diagnosis support are regarded as key enabling technologies and studied deeply. Correspondent solutions are given respectively. The assembly digitalization sub-system and the IETM sub-system are developed to validate the proposed system. And close-loop controlling of single aero-engine information is achieved, and the study provides technology support for improving level of aero-engine status digitalized management.
