It artificially generates and controls airflow to simulate the flight environment of an aircraft or other object, and measures the effects of airflow on these objects in order to study their aerodynamic characteristics. The wind tunnel test machine is one of the most commonly used and effective tools for aerodynamic experiments. The basic principle of the wind tunnel test machine is to use artificially generated airflow to simulate the flight environment of an aircraft or object. It measures the aerodynamic characteristics of a scaled model of an aircraft in a wind tunnel according to the principle of relative motion and the theory of similarity, and studies the corresponding flow phenomena and flow mechanisms.
