Drones Learn Autonomous Flying by Imitating Cars and Bikes

The algorithm DroNet allows drones to fly completely by themselves through the streets of a city and in indoor environments. It produces two outputs for each single input image: a steering angle to keep the drone navigating while avoiding obstacles, and a collision probability to let the drone recognize dangerous situations and promptly react to them.

NASA Alloy Could Fold Wings in Flight

NASA has successfully applied a new technology in flight that allows aircraft to fold their wings to different angles while in the air. Part of the Spanwise Adaptive Wing (SAW) project, the technology could produce multiple in-flight benefits to aircraft in the future, both subsonic and supersonic.

Sandia Computer Modeling Aids Solder Reliability in Nuclear Weapons

Solder isn’t the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability.

New Research Finds Cause of Alloy Weakness

Sometimes calculations don’t match reality. That’s the problem that has faced materials scientists for years when trying to determine the strength of alloys. There has been a disconnect between the theoretical strength of alloys and how strong they actually are. Why?

NASA Takes Aviation Research to the ‘Max’

NASA and the German Aerospace Center (DLR) are studying what happens with engine performance, emissions, and contrail formation when using different types of fuels in jet engines. The international collaboration uses Germany’s Advanced Technology Research Aircraft (ATRA) A320 aircraft burning alternative biofuels, while NASA’s fully instrumented DC-8 Flying Laboratory trails a safe distance behind, sampling and analyzing gases and particles within the ATRA’s wake.

‘Quantum Radio’ May Aid Communications Indoors, Underground, Underwater

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground. The technology may help mariners, soldiers and surveyors, among others.

Air Force Research Lab and Industry Advance Multi-Junction Solar Cells

Experts at the Air Force Research Laboratory (AFRL) continue to expand the scope of their technological expertise, rising above the Earth’s surface to meet the power needs of next-generation military spacecraft. A collaborative effort between the AFRL Materials and Manufacturing and Space Vehicles directorates, the Space Industrial Base Working Group, and SolAero Technologies has resulted in state-of-the art, multi-junction solar cells destined to reduce costs and increase power efficiency for military space applications.
