“Approximately SIX years ago, a new test section was designed and fabricated for the Stability Wind Tunnel to allow aeroacoustic testing. Drs. William Devenport (VT Tunnel Director), Ricardo Burdisso (VT/AVEC, Inc.), and Wing Ng (VT/Techsburg, Inc.) collaborated to create the Virginia Tech Anechoic Wind Tunnel, an innovative approach based on using “acoustically transparent” Kevlar fabric wall panels for a new test section. Acoustically treated sections line the floor and ceiling, while larger anechoic chambers are placed on each side of the test section for placement of microphone arrays or other instrumentation.”
