Coming Soon - Researchers Shine a Light on Wearable Technology

Researchers at the U.S. Army Combat Capabilities Development Command (CCDC) Chemical Biological Center are looking at LEDs to help warfighters battle chemical warfare agents (CWA). Co-primary investigators, Hui Wang, Ph.D. and John Landers, Ph.D. are investigating ways to embed tiny light sources in warfighter uniforms.

Coming Soon - New Standards Developed to Improve Metal Detector Testing

Metal detectors now appear routinely in the entrances of many schools, airports and even houses of worship. They serve as portals to correctional facilities, prisons and courthouses, and guards often wave hand-held models around the bags of incoming ticketholders at sports arenas. The increased usage is making it more important than ever to know that these machines will always work as expected and can be counted on to help detect weapons and other threats. To help meet these demands, scientists at the National Institute of Standards and Technology (NIST) have researched and developed four metal detection testing standards. Three have been published by the ASTM International standards organization and a fourth is still in development.

Coming Soon - Novel Instrument Enhances Ability to Measure Nuclear Materials

Researchers with the U.S. Naval Research Laboratory (NRL) designed and built an instrument called NAUTILUS to provide new measurement capabilities to measure nuclear, cosmo/geo-chemical, and electronic materials.

Memory Metals Shape the Evolution of Aviation

Shape-memory alloy (SMA) is a functional metal with unique properties that allow it to be trained to move on its own. Researchers at NASA Glenn partnered with Boeing to test how shape-memory alloys can be used in deployable vortex generators (VGs), the tiny fins you might have noticed on airplane wings that help control airflow during flight.

Thin Heat Shield Protects Superfast Aircraft

The world of aerospace increasingly relies on carbon fiber reinforced polymer composites to build the structures of satellites, rockets, and jet aircraft. But the life of those materials is limited by how they handle heat.

System Prevents Speedy Drones from Crashing

MIT researchers developed a trajectory-planning model that helps drones fly at high speeds through previously unexplored areas, while staying safe. The model — named “FASTER” — estimates the quickest possible path from a starting point to a destination point across all areas the drone can and can’t see, with no regard for safety.

“Circulatory” Air Conditioning Could Keep Planes Cooler

The complex network of veins that keeps us cool during the heat of summer has inspired engineers to create novel thermal management systems. A new computer program could be key to mimicking the body’s evolution-optimized cooling system in functional materials.

New Navigation System Enables Critical Assured PNT in Contested Environments

Collins Aerospace Systems, a unit of United Technologies Corp., has been selected by the U.S. Army to provide a next-generation Mounted Assured Positioning, Navigation and Timing System (MAPS) for manned ground vehicles. Known as ‘MAPS Gen II’ by the Army, the system will maintain the integrity of positioning and timing during operations in GPS-contested environments. Collins Aerospace will deliver new systems to be evaluated for a year with the potential for fielding up to 8,000 additional vehicles upon completion.

Preparing for the Consequences of a Chemical Attack

Is the U.S. ready for a chemical attack on the homeland? With the very real possibility of a chemical attack in public spaces like stadiums, religious buildings, museums and theaters, or even contamination of the food or water supply, the U.S. needs to be prepared to take appropriate action to save lives. This means having security measures in place to prevent or minimize the attack. It also means having effective medical responses that consider the quantity of medical supplies needed, transportation of those supplies to the scene, and medical facilities and personnel to care for the injured.

Armoring Satellites to Survive and Operate Through Attacks

Satellites do a lot of things — they help people navigate from one place to another, they deliver television programming, they search for new stars and exo-planets and they enable the U.S. nuclear deterrence strategy. But until recently, one thing they haven’t done — or needed to do — is defend themselves. That may soon change.
