| Abstract: | The method of developing object-oriented aeroengine numerical simulation platform is investigated.Basic class hierarchy for turbofan engine and control system performance simulation was designed.These basic classes together with some other assistant classes were coded through object-oriented computer language.The key technology for programming interactive graphical user interface and modular simulation system was introduced.A general numerical simulation platform for turbofan engine and control system was developed.Simulation results show that the platform can simulate turbofan engine dynamic process from near zero to maximal state,and the dynamic simulation error is less than 8%.The control system has quick response with suitable percent overshot.The platform is suitable for aeroengine and control system simulation. |
