Description

Technical Field

[0001] This utility model relates to the field of wind tunnel testing technology, and in particular to a wind tunnel test section wall panel expansion angle adjustment device. Background Technology

[0002] Wind tunnel testing is an experimental method that simulates airflow environments in wind tunnels to study the aerodynamic properties of objects. Its principle involves using a fan to generate controllable airflow, placing the model within the flow field, and measuring the interaction between the airflow and the object using pressure sensors, particle image velocimeters, and other equipment. During the test, wind speed, airflow conditions, and environmental parameters can be adjusted to reproduce different atmospheric conditions. Wind tunnels are classified by flow velocity into low-speed, transonic, and hypersonic types, and are widely used in aerospace, automotive, and civil engineering fields. As a key tool in aerodynamic research, it provides intuitive experimental data support for object shape design and performance optimization. The angle of the wall expansion is crucial during wind tunnel testing, as different angles have different effects. However, currently, the wall panels are adjusted separately on both sides, preventing simultaneous adjustment and leading to errors on both sides, resulting in inaccurate experimental data. Therefore, improvements are needed. Utility Model Content

[0055] In this configuration, the pulleys 5 are connected by a belt, and one of the pulleys 5 is fixedly connected to the output end of the first motor 4; the first threaded rod 6 is a bidirectional threaded rod with reverse threads at both ends, which can drive the moving parts 7 on both sides to move simultaneously in opposite directions; the unfolding wall panel 2 is provided with multiple connecting holes for rotatably connecting with the first rotating part 8 and the second rotating part 19; the mounting body 1 is provided with two sets of telescopic support plates fixedly connected to the mounting shell 10.

The connecting piece 16 then synchronously moves the placement plate 20, allowing the unfolding wall panel 2 to move. When unfolding the wall panel 2, the first motor 4 is started, which drives the pulley 5 to rotate. The pulley 5 then drives the first threaded rod 6 to rotate. When the first threaded rod 6 rotates, it drives the moving parts 7 on both sides to move. When the moving parts 7 move, they drive the first rotating part 8 to move, thereby unfolding and adjusting the wall panel 2. During unfolding, the wall panel 2 will rotate on the first rotating part 8 and the second rotating part 19. At the same time, the electric telescopic rod 12 extends and then retracts following the movement of the unfolding plate. After the wall panel 2 is adjusted, the electric telescopic rod 12 provides power to maintain the original shape and support and fix the wall panel 2.
