opened at the top and bottom of the test section. The liquid nitrogen
injection device in the wind tunnel can make the wind tunnel test
section run under a total temperature of 116 K, the total temperature
of the test section is 116−338 K, and the total pressure in the test
section is 101.4−917 kPa. The power system is located at the second
corner section downstream wind tunnel by the hole of 101 MW of
ac variable frequency motor and axial flow compressor. The diameter of the compressor is 6.1 m. The inside and outside diameters of
the flow area are equivalent. The compressor adopts single stage, with
