Precision Engineering for Advanced Aerodynamics

This wind tunnel integrates a variable speed control (0-40 m/s) and high-quality instrumentation for detailed study of boundary layer phenomena. Its modular design supports easy adaptation for various experiments, while the glass panels allow clear visualization and illumination. Built using mild steel, acrylic, and aluminium, it combines durability with performance, making it ideal for both instructional and research purposes.


Enhanced Observation and Flow Visualization

Side glass panels and internal illumination create optimal conditions for examining airflow patterns. The smoke generator included enables real-time, detailed flow visualization-essential for both teaching and analyzing complex aerodynamic phenomena. This feature enriches the learning and experimental process for students and researchers alike.


Comprehensive Measurement and Control

Users can measure velocity, static and total pressure profiles, and noise within the tunnel using provided accessories. The advanced control system and variable speed drive ensure precise airflow management, while output capabilities up to 2500 Pa support a wide range of experimental setups. This makes the wind tunnel suitable for fundamental studies and sophisticated aerodynamic investigations.
