Swarms of Autonomous Aerial Vehicles Test New Dogfighting Skills

Aerial dogfighting began more than a century ago in the skies over Europe with propeller-driven fighter aircraft carried aloft on wings of fabric and wood. An event held recently in southern California could mark the beginning of a new chapter in this form of aerial combat.

Heated Concrete Could Pave the Way for Ice-Free Runways

Iowa State University tested slabs of electrically conductive concrete at Des Moines International Airport. The test slabs are made up of 1 percent carbon fiber and a special mix of cement, sand, and rocks. The carbon fiber allows the concrete to conduct electricity, but there is some resistance to the moving electrons, which creates heat.

NASA Puts Dummies to the Test for Airplane Safety

Ten crash test dummies buckled into seats in a cut-out section of a regional jet fuselage will soon help NASA and the FAA develop new crashworthiness guidelines for future airplane designs. It is part of the FAA's efforts to address how to better assess the airworthiness of new transport planes that contain nonmetallic components. The test also included baggage in the cargo hold to see how the luggage interacts with the subfloor separating it from the dummies.

Report from SPIE 2017: Drones Spot Gas Leaks from the Sky

ANAHEIM, CA. During last week’s SPIE Defense + Commercial Sensing 2017 conference, panelists from industry, academia, and government demonstrated how miniaturized sensing platforms, and the unmanned aerial vehicles (UAVs) hosting them, can improve the detection of hazardous gas leakage.

Sandia Labs Takes Modern Approach to Evaluating Nuclear Weapons

Sandia National Laboratories is transforming how it assesses nuclear weapons in a stockpile made up of weapons at different stages in their lifecycles — some systems that have existed for decades alongside those that have undergone life extension programs. Back when the United States was developing new nuclear weapon systems, weapons typically were either in production or were retired before they aged much more than about 10 years. The U.S. today is no longer designing new systems, so scientists and engineers refurbish weapons to ensure the stockpile will function as intended and that weapons are safe, secure and reliable.

Next-Generation Fire Support Systems Boost Lethality

Soldiers view live-stream full-motion video from unmanned aerial vehicles via a smartphone. They access 3-D digital maps to send precision target coordinates. Soldiers are now relying on these advanced technologies to improve lethality and maintain battlefield dominance. These are among the improvements that will be embedded in future fire-support capabilities because the Army has started testing four upgraded systems for its Field Artillery units to provide more accurate and timely fire support to maneuver formations.

Navy Chemists Develop Field-Repairable Transparent Armor

Research chemists at the U.S. Naval Research Laboratory (NRL) have developed and patented a transparent thermoplastic elastomer armor to reduce weight, inherent in most bullet-resistant glass, while maintaining superior ballistic properties. Thermoplastic elastomers are soft, rubbery polymers converted by physical means, rather than a chemical process, to a solid. Consequently, the solidification is reversible and enables damaged armor surfaces to be repaired ‘on-the-fly’ out in the field.

The 3D Printing Landscape: Then and Now

Frequently used as a design validation and prototyping tool in its early days, the 3D printer now supports a much wider range of applications, from shape-conforming electronics to the creation of printed living tissue. Tech Briefs spoke with industry expert Terry Wohlers about 3D printing's emerging possibilities.
