Small Wind Tunnel



The AAF is equipped with a Small Wind Tunnel (SWT) for smaller-scale experiments. It is an open return type wind tunnel powered by a 4.5kW motor. The test section is designed to be highly modifiable. It may be adapted to a wide range of equipment and instruments to suit a particular experiment. 

The Small Wind Tunnel specification and performance characteristics:


Test Section Dimensions 243 cm (L) x 50 cm (W) x 40 cm (H)
Test Speeds up to 27 m/s
Free Stream Turbulent Intensity < 0.4%
Boundary-Layer thickness at 20 m/s ~40mm
