The Wind Tunnel 125 | AV5289 by Matrix is a compact, open-circuit sub-sonic wind tunnel built for bench-top use. It is engineered specifically for educational settings, from colleges to undergraduate university programs. This equipment provides a practical and intuitive platform for teaching aerodynamic principles and exploring the fundamentals of fluid flow. It simplifies complex concepts through hands-on experimentation. The system integrates a computer-controlled fan and a touch screen interface for precise operation. With built-in data acquisition and clear LED flow visualization, students can directly observe and measure aerodynamic effects, bridging the gap between theoretical knowledge and practical application.
Using the Wind Tunnel 125, students develop critical skills in experimental physics and engineering. The equipment facilitates a deep understanding of core aerodynamic principles such as Bernoulli’s equation and the behavior of air moving over various surfaces. Learners can analyze flow around both blunt and streamlined shapes, map pressure distribution on a cylinder or aerofoil, and measure real-time lift and drag forces. The included smoke generator allows for clear visualization of flow patterns. This hands-on experience teaches students how to operate manometers, interpret pressure readings, and connect empirical data with established aerodynamic theories.

Aidex is proud to supply the Wind Tunnel 125 | AV5289 to learning institutions across the Midwest. We are committed to equipping educators and students in the region with the industry-leading tools they need to succeed.
The curriculum focuses on fundamental aerodynamic principles. It covers Bernoulli’s equation, airflow over aerofoils, behavior of air around blunt and streamlined shapes, pressure distribution on cylinders and aerofoils, measurement of lift and drag forces, flow visualization techniques, and the use of manometers.
This equipment is designed for higher education environments. It is most suitable for college and undergraduate level courses in engineering, physics, and fluid dynamics, providing students with a hands-on tool for complex theories.
The integrated data acquisition system allows for direct, real-time logging of several key measurements. This includes pressure readings from the pitot-static tube and various pressure tappings, as well as the lift and drag force components acting on the test objects.
Flow visualization is achieved in two ways. The unit includes a smoke generator to create clear streamline smoke trails over test objects. Additionally, integrated LED lighting illuminates these patterns, and the transparent test section provides an unobstructed view for analysis.
Yes, the system is designed for flexibility. It features a simple thread attachment mechanism that allows students to easily design, 3D print, or otherwise create their own test pieces for aerodynamic analysis in the wind tunnel.
