Simulation and Analysis of Turbofan Engine Accelerator

A turbofan engine hydro-mechanical control system performs complex accelerating control law.In order to analyze the performance of the accelerator,the co-simulation model based AMESim and Simulink was established and the correctness of the model was verified,simulation results indicate the model has high precision.Some components' impact on accelerator was emphatically analyzed and the changes on acceleration characteristic by adjusting component parameter were displayed.The conclusions of the paper provide evidence for the improvement and modification of the hydro-mechanical control system.
