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.

Research Highlights Future Hypersonic Flight Challenges

Southwest Research Institute engineers are conducting tests that elucidate the conditions a future aircraft may experience traveling faster than 10 times the speed of sound. Because that environment is so unique, recreating realistic flight conditions to test vehicles for hypersonic flight is a challenge.

How to Dismantle a Nuclear Bomb

How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets.

Experiments Differentiate Between Underground Nuclear Tests and Earthquakes

Sandia National Laboratories researchers, as part of a group of National Nuclear Security Administration scientists, have wrapped up years of field experiments to improve the United States’ ability to differentiate earthquakes from underground explosions, key knowledge needed to advance the nation’s monitoring and verification capabilities for detecting underground nuclear explosions.

NASA Tests Electric Aircraft Power Systems

NASA Glenn has repurposed its Hypersonic Tunnel Facility to create the NASA Electric Aircraft Testbed (NEAT), a reconfigurable facility that can accommodate power systems for large passenger airplanes, like a Boeing 737, with megawatts of power.

Friendly Electromagnetic Pulse Improves Survival for Electronics

An electromagnetic pulse (EMP) emitted by a nuclear weapon exploded high above the United States could disable the electronic circuits of many devices vital to military defense and modern living. These could include complicated weapon systems as well as phones, laptops, credit cards and car computers. Also in trouble might be home appliances, gas station pumps and bank accounts.

Wind Tunnel, Lasers Provide Hypersonic Proving Ground

It’s about speed, and Sandia National Laboratories, with a hypersonic wind tunnel and advanced laser diagnostic technology, is in a position to help U.S. defense agencies understand the physics associated with aircraft flying five times the speed of sound. With potential adversaries reporting successes in their own programs to develop aircraft that can be flown at Mach 5 or greater speeds, U.S. development of autonomous hypersonic systems is a top defense priority. That has made aerospace engineer Steven Beresh of Sandia’s aerosciences department and his colleagues at the hypersonic wind tunnel popular lately.

Blast Tube Tests Simulate Shock Waves Nuclear Weapons Could Face

You can learn a lot from a blast tube when you couple blast experiments with computer modeling. Sandia National Laboratories researchers are using a blast tube configurable to 120 feet to demonstrate how well nuclear weapons could survive the shock wave of a blast from an enemy weapon and to help validate the modeling.

Unique Chamber Gives Air Force Real-World Corrosion Test Capabilities

Aircraft corrosion is a multi-faceted issue that requires more than a simple, one-dimensional approach. To enable Air Force Research Laboratory (AFRL) personnel to arrive at a complete picture and find out how to best protect valuable military assets, a unique solution was required.
