Modeling and Simulation Analysis of Hydro-mechanical Main Control System for Turbofan Engine

In order to optimize a turbofan engine hydro-mechanical main control system,the complete simulation model of the control system was established via AMESim and Simulink.The results show that a good coincidence is obtained between the simulation and actual data for turbofan engine hydro-mechanical main control system characteristics,and the model can simulate the core function at all operation conditions and process.The application of the model can reduce test cost and risk,and have significance role in production adjustment,improvement and modification.
