TL;DR: This work presents an industry based approach to PHM for one of the aircraft line replacement units (LRUs), specifically, the power drive unit (PDU) within a “generic” commercial aircraft secondary flight control system.
Abstract: The aviation industry has been utilising prognostic health management (PHM) to improve scheduled maintenance, reduce expensive aircraft on ground events (AOG) and improve active safety. PHM systems utilise legacy and real time aircraft data in conjunction with simulation models to forecast the remaining useful life (RUL) of components and systems which allow maintenance decisions to be managed. This work presents an industry based approach to PHM for one of the aircraft line replacement units (LRUs), specifically, the power drive unit (PDU) within a “generic” commercial aircraft secondary flight control system. The modelling infrastructure and its importance as a building block for the construction of a prognostic health management framework are highlighted. Example failure modes of a PDU are provided and potential benefits of PHM to mitigate these failure modes are examined. Finally simulation results from a physical model of the system in Simulink have been generated.
