Closed circuit tunnel with two test sections, one for aerodynamic testing (8 ft wide by
6 ft high section) with a wind speed capability of 105 mph, and the other
for tests that require simulation of atmospheric boundary layer wind (8 ft
wide by 7.25 ft high section) with a wind speed capability of 85 mph. This
tunnel has a gust-generation capability and can be also run in open
circuit mode. The image on the left shows the bypass duct around the fan.
The image on the right shows the test section.
