Abstract

Aero-engine performance simulation is an indispensable and important means for the whole life cycle of aero-engine. It can greatly improve the efficiency and quality of aero-engine research and development, reduce the repetition of physical tests, shorten the development cycle and reduce the development cost. Its technology is developing rapidly, and various simulation software has developed maturely. However, how to obtain the accurate simulation results of the steady state and transition state of the whole machine still has a lot of research space. This paper introduces the nonlinear dynamic performance model of mixed-flow turbofan engine in steady state based on characteristic correction diagram. In this model, the engine component model is established by using MATLAB Simulink simulation, and the interpolation calculation of component characteristic diagram is carried out to realize the calculation of working parameters and component performance parameters in the engine transition state, so as to further improve the accuracy of the model and use this model to analyze the engine performance and monitor the state.
