'Quiet' Mach 6 Wind Tunnel Helps Shape Future Aircraft

Public release date: 5 Jan 2006 Purdue University Purdue University engineers have developed a wind tunnel that is the only one of its kind in the world capable of running quietly at "hypersonic" speeds, helping researchers to design advanced aircraft and missiles. No other wind tunnel runs quietly while conducting experiments in airstreams traveling at Mach 6 -- six times the speed of sound. Read more
