W-6B Facility Description
This supersonic wind tunnel is used to conduct experiments that might otherwise tie up larger tunnels that are better utilized to test full-scale or subscale models. Typical programs involve instrument development and calibration for supersonic flows or fundamental studies of supersonic flow phenomena. The facility receives filtered air from the 40-psig central air system. The air enters a plenum-contraction section and travels into a nozzle assembly that has fixed geometry nozzle sections, able to rotate 90 degrees for ease of Mach number changes. Downstream of the nozzle is the test section, which is attached to a fixed diffuser and exits to the altitude exhaust system.

W-6B Special Features
Data acquisition and recording is via a laboratory standard ESCORT D system. Particular data acquisition capabilities include total and static pressure measurements, temperatures, hot wire anemometry, flow visualization, and laser data techniques. The test section has flexible hardware for data probe installation and a rectangular window exists in the test section for both Schlieren and Laser Doppler Anemometer measurements. A hot wire calibration rig is also available in the facility.
