About the ARC

Equipment
In 1985, a 5-stage Clark compressor was donated to UT Arlington from the NASA Ames Research Center. This compressor now serves as the backbone for the wind tunnel operation at this facility. The compressor was originally rated at 3000 psi, 2000 cfm and 1250 hp. Upon arriving at UT Arlington, the pressure was downgraded to 2000 psi. The power consumption during full-load operation is approximately 1.6 MW. The compressor is operated using a control board that continuously monitors the performance of each stage. Air is transferred to the wind tunnels using a series of gate valves and regulators controlled by several smaller boards located throughout the building. The dehydrator tank system was refurbished in 2007 to provide air with a dewpoint at -40 F. A Kellogg-American, 175 psi compressor is used for auxiliary pneumatic control systems.
