Development and Application of Digital Aerodynamic Instability Simulation System Based on Virtual Instruments

The digital simulation system based on the aeroengine dynamic pressure instability characteristic was designed.The optimization build process and key technologies of simulation system virtual instruments were illustrated,and it was successfully applicated on the development of a turbofan engine anti-surge system.The results show that the instability characteristic of the new optimization anti-surge scheme engine can effectively control and its real-time ability and operatability are both actually increased.
