DSIAC collects and publishes articles related to our technical focus areas on the web to share with the DoD community.
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
The next time Marines hit a Pacific beach, they will have the most advanced attack helicopter in the world at their backs. Eight AH-1Z Vipers began arriving at Marine Corps Air Station Futenma in late November to permanently replace the service”s aging fleet of AH-1W Super Cobras, Marine officials said, and more are on the
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
In cooperation with the U.S. Army Research Development and Engineering Command, Army Research Laboratory (ARL), and Air Force Civil Engineer…
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
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
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
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
Setting the theater requires sustainment formations that are prepared to receive, stage, onward move, and sustain divisions and corps of expeditionary forces and our allies. Sustainment formations must build and maintain reflexive competency to execute mission essential warfighting tasks in a high tempo, full-spectrum environment where interoperability is key. As sustainment units operate in a
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,
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
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
