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|
