quality, eliminate the tunnel wall interference under transonic velocity, and
develop a self-correcting wind tunnel.
The main advantages of wind tunnel test equipment are as follows: (1)
The test conditions (including airflow state and model state) are easy to
control; (2) Flow parameters (wind direction and wind speed) can change
