  • In view of the problems that aero-engines were prone to surge false alarm,misjudgment and failure of anti-surge,the anti-surge effects of a single-shaft aero-engine with core drive fan stage (CDFS) at different measurement points using different signal processing methods and anti-surge control logic designs were compared and analyzed.The surge control system was verified by the fuel step forced-surge on the high altitude simulation test.The results show that the pulsation amplitude of A value at the measurement point 2 is 4 times of that at the measurement point 1,and the accuracy of surge detection by hardware is 100%.The control method by fuel step can successfully realize the engine forced-surge,and the anti-surge control logic can successfully make the engine surge exit and restore to the present state.
