Abstract

Abstract: A co-simulation method for fuel regulator fault diagnosis in a certain type of turbofan engine is performed, which consists of AMEsim Model of main fuel control system and Simulink Model of aero-engine. The AMEsim Model of main fuel system and Simulink Model of aero-engine are built and their accuracy is validated by experiments and the engine’s operating data, respectively. The co-simulation model based on the main fuel control system and the aero-engine is proposed through the interface of AMEsim and Simulink software. The typical faults and obviation methods are simulated by the co-simulation model. The research shows that the problem of fuel regulator fault diagnosis can turn into pattern recognition of feature parameters in aero-engine field. The method provides not only troubleshooting solutions and fault diagnosis for fuel regulator system, but also supports theory and sample for establishing standards of engine’s condition based maintenance.

Key words: aero-engine, fuel regulator, fault diagnosis, co-simulation
