Semi-physical Simulation Experiment System of Fuel Control System for an Aeroengine

摘要

The thermodynamic model of an aeroengine was established. The laboratory working condition of the fuel controller, fuel flow proportioner and low-pressure fuel-feed system of an aero-engine were built. The mathematic model of the aeroengine was ran in the computer. Using RS422 Bus technology, the semi-physical simulation experiment system of the fuel control system for the aeroengine was established with engine model. And then the experiment results demonstrate that the semi-physical simulation experiment system can simulate the transient state and steady state for the aero-engine effectively. These results lay a solid foundation in the further research of the FADEC system for engine and the application of advanced control theory to control system of engine.
