Large Wind Tunnels / Custom Made Products


We, Japan Wind Tunnel Manufacturing Inc., design and manufacture all sizes of wind tunnels. Especially for customers who need higher performance requirements (flow area size, top wind speed, flow quality, etc.) than our Aero Optim series, We manufacture custom made wind tunnels that meet our customer's requirements. Also, we design and manufacture measurement devices (Traversing device, 6-axis force-torque sensors, etc.). Please feel free to contact us for custom made products.

Design Samples

This is a design sample of an Eiffel-type wind tunnel with a flow area of 2m × 2m (Specifications: Max wind speed 30m/s, Wind Speed Distribution under ±1%, Turbulence Intensity under 1%, equipped with 6-axis force-torque sensor with an automatic turntable). We use clustered multiple small size fans rather than 1 large fan for our wind tunnels. In this design sample, four 37kW axial fans are used to create a total output of 148kW. Large size fans are usually a One-off product specially made for the wind tunnel. They are expensive to mend or replace when the fan gets out of date. On the other hand, by using clustered multiple small size fans, we can use mass‐produced products (fan blades, motors, inverters) that cost low, easy to replace or update. Also, the wind tunnel can be shorter in size by using clustered multiple small size fans. This method is used in our Aero Optim wind tunnel series making it compact, inexpensive and accurate. The Wind tunnel in the back of the image below is a design sample of an Eiffel-type wind tunnel with a flow area of 3m × 3m. We can design and manufacture Eiffel-type and Goettingen type wind tunnels matching customer's requirements. Also, we design and manufacture measurement devices (Traversing devices, 6-axis force-torque sensors, etc).
