Optical Method Detects Weak Spots in Jet Engine Coatings

Researchers have demonstrated, for the first time, that an optical analysis method can reveal weak areas in ceramic thermal barrier coatings that protect jet engine turbines from high temperatures and wear. The technique could be used to predict how long coatings would last on an airplane. The lifetime of a thermal barrier coating used on airplane turbine blades can range from as little as 1,000 hours up to 10,000 hours at full turbine thrust, even when the coating is applied in the exact same way.

NASA Tests Could Lead to FAA Integration of UAVs

NASA’s Unmanned Aircraft Systems Integration in the National Airspace System, or UAS in the NAS, project is attracting international attention as increasingly complex flight tests take place over NASA’s Armstrong Flight Research Center in California. The project is designed to develop recommendations for the FAA to safely open the skies to allow UAS to fly in the same airspace with human-piloted aircraft.

Researchers Test Minuteman III Intercontinental Ballistic Missile

As an unarmed Minuteman III intercontinental ballistic missile (ICBM) rocketed into the night sky, a team of Lawrence Livermore National Laboratory (LLNL) researchers listened intently to radio chatter and watched flight data stream in from a control room at the Ronald Reagan Ballistic Missile Defense Test Site. It was the first of two flight tests conducted recently to verify that the system could deliver a payload to target.

Airborne Sense-and-Avoid Radar for UAVs

Widespread use of unmanned aerial vehicles (UAVs) within the National Airspace System is limited because of regulatory restrictions on their access to shared airspace. The Airborne Sense and Avoid (ABSAA) Radar Panel, a phased array antenna developed by MIT Lincoln Laboratory, has the potential to facilitate the introduction of UAVs into the national airspace.

Rising Temps Could Limit Aircraft Takeoffs

Rising temperatures due to global warming will make it harder for many aircraft around the world to take off in coming decades, says a new study by Columbia University. As air warms, it spreads out, and its density declines. In thinner air, wings generate less lift as a plane takes off. Depending on aircraft model, runway length, and other factors, at some point, a packed plane may be unable to take off safely if the temperature gets too high.

Researchers Achieve Breakthrough in Nuclear Threat Detection Science

Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America’s ports and borders.
