Wind tunnel

Overview
The Ballastco wind tunnel is an open-circuit aerodynamic test facility designed for R&D, academic laboratories and industrial aerodynamics testing. It provides laminar airflow with turbulence intensity below 1%, a wide adjustable airspeed range and a low-blockage test section to ensure repeatable, accurate measurements for model testing and sensor calibration.

Key Features

• Excellent flow quality: Laminar airflow with turbulence intensity <1%, achieved using specially designed stainless-steel flow-straightening screens.
• Wide dynamic range: Adjustable airspeed from 0.4 m/s to 45 m/s for low-speed to medium-speed aerodynamic studies.
• High-precision test section: Spacious test chamber with a low blockage ratio to minimize interference and improve measurement accuracy.
• Clear visual access: Transparent acrylic viewing panels allow full observation of model behavior and flow visualization.
• Safe and flexible operation: Open-circuit layout with high-resolution speed control; suitable for wind sensor calibration and repeatable laboratory testing.
