Flow control of double bypass variable cycle engine in modal transition
文献摘要：
To study the change mechanism and the control of the variable cycle engine in the pro-cess of modal transition,a variable cycle engine model based on component level characteristics is established.The two-dimensional CFD technology is used to simulate the influence of mode selec-tion valve rotation on the engine flow field,which improves the accuracy of the model.Further-more,the constant flow control plan is proposed in the modal transition process to reduce the engine installed drag.The constant flow control plan adopts the augmentation linear quadratic reg-ulator control method.Simulation results indicate that the control method is able to effectively con-trol the bypass ratio and demand flow of the variable cycle engine,and make the engine transform smoothly,which ensures the stable operation of the engine in modal transition and the constant demand flow of the engine.
