Aerodynamics Laboratory Facilities, Equipment, and Capabilities


Security Lab




The following facilities, equipment, and capabilities are available in the Aerodynamics Laboratory Facilities and Equipment

(1) Subsonic, open-jet wind tunnel with 1.8-meter (m) by-1.8-m (6-foot (ft) by 6 ft) cross section and a 13.4 m/s (44 ft/s) speed range (Figure 1).

This image shows two engineers standing in front of a wind tunnel, which measures 1.8-meters by 1.8 meters (6 feet by 6 feet). The engineers are mounting a model bridge deck in front of the wind tunnel.
