革新涡轮加速器模态转换特性研究

The engine performance simulation model of Revolutionary Turbine Accelerator (RTA) was built based on the component characteristic, to research the performance in mode transition process and corresponding control method. Different mode transition methods were simulated and compared in detail, and the mode transition control law along the given flight trajectory was designed. It can be concluded that the RTA can conduct mode transition at Ma1. 6, and operate steadily in Ma0~4.0. The mode transition process can occur in both maximum mechanical load and maximum thermal load condition, with 8 times variation of bypass ratio, to realize the high thrust performance during the flight.
