NASA Researchers Work to Turn Blue Skies Green

A big part of NASA's work to reduce the environmental impact of aircraft has moved into phase two.

A semi-span jet model is scheduled to be tested in NASA Langley's 14-by-22 Foot Subsonic Wind Tunnel this winter to evaluate aircraft noise reduction technologies as part of the Flap and Landing Gear Noise Reduction Flight Experiment.

Listening for the Boom and Rattle of Supersonic Flight

NASA engineers test people's reactions to simulated sonic booms to help develop technologies that might allow supersonic passenger jets to fly over land.

More than 100 subwoofers and mid-range speakers generate the sonic boom noises that test subjects rate from least to most annoying.

Researcher Jonathan Rathsam briefed sonic boom noise test listeners before they heard the more than 200 sounds they were asked to assess as part of NASA's supersonic technology research.

NASA Books Reveal Wisdom Gained from Failure

The latest in NASA Aeronautics' Book Series tells the stories of lessons learned from accidents involving remotely piloted or autonomous aircraft.

"Crash Course" chronicles the lessons learned from failures over the decades of remotely piloted or autonomous unmanned aircraft systems used by NASA, from Perseus to the X-36 and from subsonic to hypersonic speeds.
