Abstract :
The performance of aircraft engine has a great influence on the operating costs and use efficiency, while performance deteriorating to a great degree may lead to engine failure. As a result, it is of great importance to analyze the performance of aircraft engine. In this paper, the performance deterioration theory of aircraft engine components was analyzed based on simulation with component level model of aircraft engine built by Matlab and several parameters including compressor outlet pressure, compressor outlet temperature, turbine outlet pressure, turbine outlet temperature, fuel flow, thrust and etc, were evaluated with grey relation analysis. The influence of component deterioration on engine performance was discussed. The simulation results show that component deterioration has a great influence on the engine performance, and performance deterioration evaluation analysis of aircraft engine based on simulation is of theoretical importance and application value for gas turbine health management.
