Invention may get Army quadcopters to move faster

Army Researcher Dr. Jean-Paul Reddinger invents a new hinge that enables load-bearing, large, Army quadrotors to climb a few dozen feet in seconds. Credit: U.S. Army graphic Researchers believe a new hinge is the key to get load-bearing, large, Army quadrotors to climb a few dozen feet in seconds. Dr. Jean-Paul Reddinger, a research aerospace engineer with the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory, is studying how quickly a quadrotor the size of…

NASA Uses 3D Printing to Bring the Cost of Space Exploration Down to Earth

Young Industries, a leading manufacturer of custom-designed equipment for handling dry bulk materials, had been using SOLIDWORKS 3D applications for two decades. The company also used 2D CAD for critical workflows including modifying legacy drawings, creating new layouts and sketches, and developing diagrams. They knew it was time for a change when their MountainTop 2D design software experienced hardware and software failures. After a thorough evaluation of 2D design software, DraftSight rose to the top of Young Industries’ list. The…

Army looks to improve quadrotor drone performance

Credit: The Army Research Laboratory When an aircraft veers upwards too much, the decrease in lift and increase in drag may cause the vehicle to suddenly plummet. Known as a stall, this phenomenon has prompted many drone manufacturers to err on the side of extreme caution when they plan their vehicles’ autonomous flight movements. For vertical takeoff and landing tail-sitter drones, most manufacturers program the aircraft so that the vehicle body turns very slowly whenever it transitions from hover to…

Huge drone set to launch satellites in mid-air

We all have images in our mind of rocket launches from Cape Canaveral Air Force Station hurtling astronauts into space and satellites into orbit. But those launches may be a thing of the past as a new generation of drones that can do the same job cheaper, safer and better steps into play. Alabama-Based Aevum unveiled its Ravn X Autonomous Launch Vehicle Wednesday that it says is the world’s largest unmanned aircraft system. The Ravn X fleet, with aircraft at…

Army computer models unveil secret to quieter small drones

Army researchers identify new ways to make small UAVs like PUMA quieter in densely-populated areas. Credit: Sgt. Hillary Rustine It’s no secret the U.S. Army wants its small unmanned aerial systems to operate quietly in densely-populated regions, but tests to achieve this can be expensive, time-consuming and labor-intensive according to researchers. Miranda Costenoble, a graduate student researcher with the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory, presented work at the Vertical Flight Society’s 76th…

Canceling unnecessary and unwanted noise

Credit: Pixabay/CC0 Public Domain Reporting in the journal Scientific Reports, the team of Tong Xiao, Xiaojun Qiu and Benjamin Halkon highlight the positive impacts for health and wellbeing of their ‘virtual Active Noise Control/Cancelation (ANC) headphone’ and its enhanced ability to reduce ambient noise. By integrating laser-based technology—which can deal with high frequencies—into headrests they eliminate the need for users to wear head/ear phones or buds. So, in an open plan or home office, you can cancel out colleagues’ chatter,…

Electronic skin has a strong future stretching ahead

KAUST researchers have developed a durable “electronic skin” that can mimic natural functions of human skin, such as sensing temperature and touch. Credit: © 2020 KAUST A material that mimics human skin in strength, stretchability and sensitivity could be used to collect biological data in real time. Electronic skin, or e-skin, may play an important role in next-generation prosthetics, personalized medicine, soft robotics and artificial intelligence. “The ideal e-skin will mimic the many natural functions of human skin, such as…

The science of windy cities — ScienceDaily

Global population and urbanization have boomed over the last few decades. With them came scores of new tall buildings, drones, more energy-efficient ventilation systems, and planned air taxis by Uber and other companies. But these technological advancements must contend with a natural physical phenomenon: wind. Scientists presented the latest findings on modeling and predicting urban airflow — in the hope of building better buildings, cities, and transportation — at the 73rd Annual Meeting of the American Physical Society’s Division of…

Shift in atmospheric rivers could affect Antarctic sea ice, glaciers — ScienceDaily

Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research. Atmospheric rivers are long, narrow jets of air that carry huge amounts of water vapor from the tropics to Earth’s continents and polar regions. The new study finds atmospheric rivers in the Southern Hemisphere…
