This directory contains public-domain information on the Boeing/AFOSR Mach-6 Quiet Tunnel at Purdue University. Most of the files are AIAA papers published from 1998 to the present. One earlier paper from 1996 contains some discussion on a Mach-4 prototype facility. Some of the files contain other data, such as images of the Mach-6 tunnel. More documentation and more papers exist. For more information, contact Prof. Steve Schneider, Purdue University, School of Aeronautics and Astronautics, West Lafayette, Indiana 47907-1282.
