借助Matlab搭建完整的双轴涡轮风扇发动机模型,对各部件进行封装,利用Simulink显示模块观察仿真结果。在动态仿真时,引入容积动力效应,避免反复迭代过程,提高模型实时性。与GSP仿真软件结果进行对比,结果表明:所建立的模型具有较高精度,可以准确捕捉航空发动机的动态响应和稳态响应。
藉助Matlab搭建完整的雙軸渦輪風扇髮動機模型,對各部件進行封裝,利用Simulink顯示模塊觀察倣真結果。在動態倣真時,引入容積動力效應,避免反複迭代過程,提高模型實時性。與GSP倣真軟件結果進行對比,結果錶明:所建立的模型具有較高精度,可以準確捕捉航空髮動機的動態響應和穩態響應。

A integrated two-spool turbofan engine model was built by the Matlab to package each component. The simulation results were observed by Simulink's display module. The dynamic effects of volume was introduced to avoid the iterative process and improve the real time of the model. The simulation results compared with GSP show that the model has higher precision to caputured accurately dynamic and steady state responses of aeroengine.
