New 30" Anechoic Wind Tunnel

Preparing for a propeller noise experiment in the Virginia Tech 30" Anechoic Wind Tunnel

Our new 30" wind tunnel is running! This tunnel will expand our current capabilities as well as provide a facility for experiments that don't require the capability of our larger Stability Wind Tunnel. In addition, the test section of this facility is convertible from an open-jet facility to a closed Kevlar-wall test section. The test section is designed to be fully anechoic down to 400 Hz. Currently, the facility is being calibrated and its performance assessed while preparing for its first experiments of propeller noise!
