| Abstract: | The survey of the NF-6 wind tunnel is introduced briefly.The Mach number closed-loop control system in the NF-6 wind tunnel is expounded,especially in detail Mach number measurement,control strategy and control process,and the sketch of Mach number closed-loop control system is analyzed.The compressor stator vane control is as the first level coarse adjustment method of Mach number control,and PI controller is as the second level fine adjustment method of Mach number control.The accurate control experiment of Mach number in the test section is performed.The test result indicates that the control precision is under 0.002,the Mach number closed-loop control system has achieved good controlling effect in practice. |
| Keywords: | Mach number closed-loop control control strategy PI controller NF-6 wind tunnel |
