Metric-Sized Metal Shapes

Parker Steel Company (Maumee, OH) offers metric-sized metals suitable for applications where presized metric parts are needed....

A single antenna can be used for both transmission and reception. To accomplish this, the transmission must be isolated from the reception. In Figure 1, a radio frequency...

In July of 2016, a refrigerator truck packed with explosives detonated next to a crowded apartment block in Baghdad’s Karrada neighborhood. The blast killed 323 people...

In the old days, a slingshot, BB gun, rifle or cannon was only as smart as the marksman taking aim. Now, many weapons are guided to their targets with the precision of infrared sensors and lasers. The...

Remote measurement of physiological signals has a number of advantages over traditional contact methods. It allows the measurement of...

Dust storms (5 to 100 km across) often originate from multiple dust-emission sources (1 to 10 km across). Remote-sensing-based dust-source identification is a challenge. A...

The U.S. Army Corps of Engineers (USACE), CHL, FRF, had a need for a remote real-time data collection system to control instruments and log and communicate data from five...

Topology Control in Aerial Multi-Beam Directional Networks

In multi-beam directional networks, nodes are able to simultaneously transmit to all neighbors or receive from all neighbors. This spatial reuse allows for high throughputs, but in dense networks can cause significant interference. Topology control (i.e., selecting a subset of neighbors...

Communication on the battlefield is a life-or-death matter. You can't take chances with RF devices or power units malfunctioning or failing. A soldier's life may depend on...

As aerospace and defense manufacturing becomes increasingly digitized—from the earliest design stages to the factory floor and beyond—data accuracy is fundamental to...

NASA engineers tested a 3D-printed rocket engine prototype part made of two different metal alloys via an advanced manufacturing process. The part was low-pressure, hot-fire-tested...

Green Aerospace Test Uses No Explosives

Sandia National Laboratories has successfully demonstrated a new, more environmentally friendly method to test a rocket part to ensure its avionics can withstand the shock from stage separation...

As an unarmed Minuteman III intercontinental ballistic missile (ICBM) rocketed into the night sky, a team of Lawrence Livermore National Laboratory (LLNL) researchers...

In the study of combustion characteristics of liquid rocket fuels, it is customary to either study the combustion of liquid fuel droplets...

NeXtRAD is a dual-band, dual-polarization, multistatic radar system under development at the University of Cape Town (UCT) in...

The provision of integrated modeling, simulation and optimization tools to effectively support all stages of aircraft design remains a critical challenge in the aerospace...

Engineers at the U.S. Army Aviation and Missile Research, Development and Engineering Center (AMRDEC) are working on a trio of technologies to explore improving existing air and...

From a distance, the drop of a mock nuclear weapon — containing only non-nuclear components — was a mere puff of dust rising from a dry lake bed at Nevada’s Tonopah Test...

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...

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...

Pulsed signals are widespread in radar and other electronic warfare (EW) applications, and they must be accurately measured for manufacturing, design of countermeasures, and threat...

The primary metrics that prohibit the use of microelectromechanical systems (MEMS) gyroscopes for navigation-grade inertial navigation units (IMUs) are angle...

Researchers at Missouri University of Science and Technology and The Boeing Company established a new nondestructive evaluation (NDE) laboratory that uses millimeter-wave technology to improve...

Long-range bombers may have missions halfway around the world. Fighter jets may have to stay in the air longer than their relatively small fuel tanks will allow, or may find...

Whether for multi-channel analysis, or for wider analysis bandwidth in a measurement, high bandwidth oscilloscopes offer an alternative to traditional...

Recently, in operando optical investigations of high temperature solid oxide electrochemical cells (SOECs) have gained significant traction with several...

As part of Project Agreement on Military Operations in Urban Terrain (MOUT), the US Army Research...

An energized electric power cable generates low-frequency electric and magnetic fields that are related to the voltages and currents. Especially at wavelengths...
