Army Hopes to Use AI to Create More-Efficient Fuel Cells

As part of an effort to address the gap the U.S. Army faces in its need for long-lasting power and batteries for warfighters, an Army-funded research team has developed an artificial intelligence (AI) system that officials say identifies a promising material for creating more-efficient fuel cells. Researchers said the system, developed at Cornell University, is a potential breakthrough in both materials science and machine learning. It relies on a collective of algorithmic bots, each performing a distinct task and sifting through hundreds to thousands of combinations of elements to create a map of phases—arrangements of atoms in relation to each other—that humans can then use to determine which might work as a new material.

Inside Story: The Role of the SFFs in Rugged HPEC Computing

For more than 30 years, Aitech has worked with its customer to develop high reliability embedded systems for rugged commercial, military, defense and space applications. Recent company initiatives have focused on the integration of Intel-based rugged PCs and GPGPUs into small form factors, meeting the growing need for inherent security features within hardware platforms and advancements in power, processing and communications in mission-critical systems. Here we talk with Doug Patterson, VP of Global Marketing for Aitech to look at how shrinking system size, coupled with increasing computing density, is impacting embedded computing design principles.

Software Accelerates Hypersonic Engine Development

Argonne National Laboratory and the Air Force Research Laboratory developed a new numerical modeling tool that allows for a better understanding of rotating detonation engines (RDEs). Unlike conventional gas turbine engines, RDEs leverage high-intensity, self-sustaining detonation to rapidly consume the fuel-air mixture, typically in a ring-shaped, cylindrical chamber.

Study Could Help Aircraft Avoid Dynamic Stall

University of Illinois researchers are studying the physics of dynamic stall so that it can be used beneficially and reliably by aircraft. The problem has been studied at low speeds but at higher speeds, the process becomes significantly disorganized and difficult to understand.

Navy Launches Virtual Training Tech for Aircraft Carrier Flight Deck Crews

One of the most dangerous environments in the U.S. Navy is the deck of an aircraft carrier. Catapult systems that can remove limbs, furious engines, whipping propellers, and high winds create a hectic environment. The driving force behind all of these activities is helping a pilot land an aircraft on a short slab of pitching steel in the middle of the ocean. Although pilots are the stars of the show, they could not accomplish their missions without the support of flight deck crews, who are responsible for safely launching and recovering aircraft.

DETECTING PLASTIC LANDMINES

Hidden PFM-1 anti-personnel landmines are unexploded ordnance (UXO) devices that pose a difficult challenge to conventional landmine detection methods like metal detecting because the mines are primarily composed of plastic and only weigh 75 g. As a remnant of the Soviet-Afghan War, there are an estimated 10 million such devices scattered throughout Afghanistan. These mines remain in isolated locations, frequently out of reach of de-mining nongovernmental organizations (NGOs) and act to thwart local economic and social development. The PFM-1s are infamously referred to as “toy mines,” as children often mistake the mines for toys and set off the 525 kg of cumulative pressure it takes to detonate them.

Optimizing Winglets for More Efficient Flight

Airplane winglets reduce drag, which can translate to higher speed or to allow a pilot to throttle back and save fuel. It also helps to reduce wingtip vortices that can be problematic for airplanes flying in their wake. Although winglets have been around since the mid-1970s, there is still a wide variety of shapes, sizes, and angles.

Aircraft Scheduling Models Ease Traveler Frustration

Flight schedules that allow for a little carefully designed wiggle room could prevent the frustration of cascading airport delays and cancellations. By focusing on the early phases of flight schedule planning and delays at various scales, researchers have developed models to help create schedules that are less susceptible to delays and easier to fix once disrupted.
