Description

Technical Field

[0001] The utility model relates to the technical field of wind tunnels, in particular to a wind tunnel detection mechanism. Background Art

[0002] A wind tunnel, or wind tunnel laboratory, is a pipe-shaped experimental device that artificially generates and controls airflow to simulate the flow of gas around an aircraft or object. It can measure the effects of airflow on the object and observe physical phenomena. It is one of the most commonly used and effective tools for conducting aerodynamic experiments.

[0003] Patent document CN218727401U discloses a wind tunnel detection mechanism for detecting anemometer speed and direction. The mechanism comprises a housing, an air duct enclosed by the housing, and a fan located within the duct. The rotation of the fan creates airflow within the duct. The mechanism includes a movable closed test section, a mating flange connected to the front and rear air ducts, and a gap between the mating flanges to facilitate movement of the closed test section. The mating flanges are provided with an annular groove and an inflatable sealing ring located within the groove. When inflated, the inflatable sealing ring expands to fill the gap between the mating flanges and form a seal. The utility model provides a mating flange between the closed test section and the front and rear air ducts, and an inflatable sealing ring is provided on the mating flange to facilitate sealing of the flow duct, thereby improving efficiency and achieving a good sealing effect.

[0004] However, although the existing wind tunnel detection mechanism can detect objects during use, the environment itself is relatively complex during the detection process. In addition, the wind tunnel detection mechanism cannot simulate different environments according to the detection requirements to test the aerodynamic performance, flow field characteristics, etc. of the object, resulting in poor detection accuracy of the wind tunnel detection mechanism. For this reason, we propose a wind tunnel detection mechanism. Utility Model Content
