Abstract


Based on the failure analysis of the Hydro-Mechanical Unit (HMU) of aeroengine fuel control system, both of data-based and model-based methods are proposed to diagnose the typical faults of the Fuel Metering Device (FMD). Firstly, the AMESim model of FMD was established. Then its fault tree was set up and simulation analysis for two typical faults was conducted. Finally, two approaches were applied to these faults diagnosis and simulation results show their effectiveness.
