Aircraft Arrival Technology Will Reduce Flight Delays

Flight Deck Interval Management (FIM) promises to safely increase the number of airplanes that can land on the same runway at busy airports by more precisely managing the time, or interval, between each aircraft arrival.

T-rays Will “Speed Up” Computer Memory By a Factor of 1,000

Together with their colleagues from Germany and the Netherlands, scientists at the Moscow Institute of Physics and Technology (MIPT) have found a way to significantly improve computer performance. They propose the use of so-called T-waves – or terahertz radiation – as a means of resetting computer memory cells. This process is several thousand times faster than magnetic-field-induced switching.

First Stryker Vehicle Prototype With 30mm Cannon Delivered to Army

The first prototype Stryker Infantry Carrier Vehicle, outfitted with a 30mm cannon, has been delivered to the U.S. Army. The upgraded Stryker vehicle will be known as the Dragoon, the name of the 2nd Cavalry Regiment. The prototype also features a new fully-integrated commander's station, upgraded driveline componentry and hull modifications, according to a press release from Program Executive Office Ground Combat Systems.

‘Nano-Kebab’ Fabric Breaks Down Chemical Warfare Agents

Researchers have created a fabric material containing nanoscale fibers that are capable of degrading chemical warfare agents (CWAs). Uniform coatings of metal-organic frameworks (MOFs) were synthesized on top of the nanofibers, forming unique kebab-like structures. These MOFs are what break down the CWAs, rendering them harmless.

Fragment Tracking Gives Insights Into What Happens In Explosions

A bang and a swirl of dust from detonating 9 pounds of plastic explosive in the desert signaled the beginning of tests that — thanks to advances in high-speed cameras, imaging techniques and computer modeling — will help Sandia National Laboratories researchers study fragmenting explosives in ways that weren’t possible before.

Composites Self-Heal at Very Low Temperatures

Scientists developed a method of allowing materials, commonly used in aircraft, to self-heal cracks at temperatures well below freezing. A healing efficiency of more than 100% at temperatures of -60 °C was obtained in a glass fiber-reinforced laminate, but the technique could be applied across a majority of self-healing composites.

Navigation System Uses Existing Cell Signals – Not GPS

Researchers developed a highly reliable and accurate navigation system that exploits existing environmental signals such as cellular and Wi-Fi, rather than the Global Positioning System (GPS). The technology can be used as a standalone alternative to GPS, or complement current GPS-based systems to enable highly reliable, consistent, and tamper-proof navigation in autonomous vehicles such as unmanned drones.

NASA’s Folding Wing Reduces Drag and Increases Efficiency

NASA’s Spanwise Adaptive Wing (SAW) concept permits the outboard portions of the wings to move to the optimal position during operation. This could increase efficiency by reducing drag, and increasing lift and performance. The ability to achieve an optimal wing position for different aspects of flight may also produce enough yaw control to allow for rudder reduction on subsonic and supersonic aircraft.

Antenna Design Turns Entire Vehicles into Broadcasting Equipment

High-frequency antennas transmit radio waves across vast distances and even over mountain ranges using very little energy, making them ideal for military communications. These devices, however, need to be huge to operate efficiently. Instead of adding more bulk, however, University of Wisconsin–Madison engineers are working to increase the effective size of antennas by turning the military vehicles that carry them into transmitters,using the structures that support the antennas themselves to help broadcast signals.
