To study the change mechanism and control of variable cycle engine in process modal transition, a model based on component level characteristics is established. The two-dimensional CFD technology used to simulate influence mode selection valve rotation flow field, which improves accuracy model. Furthermore, constant plan proposed transition reduce installed drag. adopts augmentation linear quadratic regulator method. Simulation results indicate that method able effectively bypass ratio demand engine, make transform smoothly, ensures stable operation engine.
