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.

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.

Air Force Scientists Discover Unique Stretchable Conductor

The Air Force Research Laboratory has developed liquid metal systems which autonomously change structure so that they become better conductors in response to strain. Conductive materials change their properties as they are strained or stretched. Typically, electrical conductivity decreases and resistance increases with stretching.

Air Force Invents Aircraft Tire Change Tool

How many airmen does it take to change a cargo aircraft tire? Too many. The U. S. Air Force’s largest aircraft, the C-5M Super Galaxy, has 28 tires. The current tire changing method is performed several times a week. It is a complicated, multistep procedure that requires up to five people working together for an extended period of time with a number of safety risks due to the size and weight of the tires and tools.

Pilot Assistance System Enables Low-Noise Landings

Approach and landing are among the most complex phases of a flight. In order to enable pilots to fly as quietly as possible, the German Aerospace Center (DLR) developed the Low Noise Augmentation System (LNAS), a pilot assistance system that uses a display in the cockpit to show pilots exactly what action to take for a low-noise approach.

Supersonic Aircraft Window Goes Virtual

NASA’s X-59 Quiet SuperSonic Technology (QueSST) aircraft will eliminate the cockpit’s forward-facing window, replacing it with the eXternal Visibility System (XVS) that uses a 4K monitor that serves as the central window and allows the pilot to safely see traffic in his or her flight path. The XVS displays stitched images from two cameras outside the aircraft combined with terrain data from an advanced computing system.

Coating Improves Pilots’ Visibility in Rainstorms

An Air Force Research Laboratory-developed product called HydroSkip repels water from aircraft transparencies, addressing the issue of limited visibility caused by heavy rain that can impair the pilot’s ability to navigate the plane and land safely.

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.
