Protecting Engineering Materials from Water Impact

Erosion caused by the impact of water droplets on component surfaces can lead to failures in key technological applications. For example, in steam generating plants, the leading edge of turbine blades suffer major erosion damage from the steam driving the turbines, requiring costly maintenance and repair with consequent loss of generating capacity. Similarly, erosion caused

Nano-Sized Hydrogen Storage System Increases Efficiency

Lawrence Livermore scientists have collaborated with an interdisciplinary team of researchers including colleagues from Sandia National Laboratories to develop an efficient hydrogen storage system that could be a boon for hydrogen powered vehicles. Hydrogen is an excellent energy carrier, but the development of lightweight solid-state materials for compact, low-pressure storage is a huge challenge. Complex

US Air Force Fighters & Drones Will Fire Laser Weapons by the 2020s

The Air Force is increasing computer simulations and virtual testing for its laser-weapons program to accelerate development and prepare plans to arm fighter jets and other platforms by the early 2020s. To help model the effects of such technologies, the service has awarded Stellar Science a five-year, $7 million contract for advanced laser modeling and

Deployable Waste-to-Energy Conversion for Expeditionary Forces

In cooperation with the U.S. Army Research Development and Engineering Command, Army Research Laboratory (ARL), and Air Force Civil Engineer…

Demystifying the A2/AD Buzz

Anti-access and area denial — best known by its shorthand A2/AD — has crossed the buzzword threshold. It’s a quite impressive feat for such a distinctively non-user friendly and technical concept, which alludes to that family of military capabilities used to prevent or constrain the deployment of opposing forces into a given theater of operations

Global Ionospheric Modeling Using Multi-GNSS: BeiDou, Galileo, GLONASS and GPS

The emergence of China’s Beidou, Europe’s Galileo and Russia’s GLONASS satellites has multiplied the number of ionospheric piercing points (IPP) offered by GPS alone. This provides great opportunities for deriving precise global ionospheric maps (GIMs) with high resolution to improve positioning accuracy and ionospheric monitoring capabilities. In this paper, the GIM is developed based on

IAI Unveils Multichannel Controlled Reception Pattern Antenna GPS Anti-Jam Solution

TEL AVIV — Israel Aerospace Industries (IAI) will debut at the upcoming Aero India exhibition in Bangalore an export-approved system to defend against GPS jamming. Called ADA after the special adaptive antennas developed by the firm’s MALAM division, the system is operational in Israel and is slated to be installed in yet another Israeli Air

Army Needs Highly Flexible, Responsive Internet of Things for the Battlefield

To serve the soldiers of the future through connected devices, the military will need dynamic and adaptable networks. The Internet of Things is coming to the military in a big way, probably sooner than most think, according to the Army’s John Pellegrino. To make sure that tomorrow’s warfighters have all of the tools they need

Army Picks Sig Sauer”s P320 Handgun to Replace M9 Service Pistol

The U.S. Army on Thursday awarded Sig Sauer a contract worth $580 million to make the next service pistol based on the company”s P320 handgun. Sig Sauer beat out Glock Inc., FN America and Beretta USA, the maker of the current M9 9mm service pistol, in the competition for the Modular Handgun System, or MHS,

Lethal Miniature Aerial Munition System Program to Improve Loitering Munitions

Small drones are lethal battlefield weapons. Soldiers can launch them from behind cover, then locate, identify, and engage a target several miles away without ever exposing themselves to the enemy. The grenade-sized warhead can destroy a light vehicle, and because it can attack from any direction – including a vertical dive – a drone negates

Miniature Autonomous Underwater Explorers Mimic Ocean Life

Scripps researchers collaborate on new technology study using “robotic plankton”. Underwater robots developed by researchers at Scripps Institution of Oceanography at the University of California San Diego offer scientists an extraordinary new tool to study ocean currents and the tiny creatures they transport. Swarms of these underwater robots helped answer some basic questions about the

NASA Spacecraft to Test ”Green” Propellant Passes Major Preflight Milestone

Like all rocket engines, the small thrusters that a spacecraft or satellite fires to maintain or change positions need fuel. Currently, many use hydrazine — a toxic and corrosive fuel that requires special handling and equipment. NASA”s Green Propellant Infusion Mission (GPIM) recently took another major step toward demonstrating the capabilities of a new propellant
