Quiet--Testing In Progress

Quiet--Testing In Progress: The Air Force is utilizing the world’s only quiet hypersonic wind tunnel at Purdue University to support the X-51A WaveRider Scramjet Engine Demonstrator program. The tunnel, developed by Boeing and the Air Force Office of Scientific Research, is unique in allowing engineers to assess the performance of air vehicles traveling at speeds reaching 4,000 mph or about Mach 6. With it, they can study airflow over the nose of X-51A to optimize its design. “Researchers are now able to characterize, or describe, the onset of the laminar to turbulent transition on hypersonic aircraft such as the X-51A with clarity that would be impossible using a conventional wind tunnel,” said John Schmisseur, AFOSR program manager. The X-51A completed its critical design review last June and fired the engine for the first time. (USAF report by Molly Lachance)

Family Momentum
"In many ways, this was what the Year of the Air Force Family was all about—connecting airmen and their families with the resources they need. I have confidence the Air Force will capitalize on this strong momentum in the years ahead by continuing to improve our family support programs and ensuring people know what resources are available."
—Suzie Schwartz, wife of USAF Chief of Staff Gen. Norton Schwartz, commenting on the accomplishments of the Year of the Air Force Family initiative that concluded in July, in a statement provided to the Daily Report, Aug. 22, 2010.
