Sending a human into space and doing it efficiently presents a galaxy of challenges. Koki Ho, University of Illinois assistant professor in the Department of Aerospace Engineering, and his graduate students, Hao Chen and Bindu Jagannatha, explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and conducting research, published today in the Journal of Spacecraft and Rockets, to create a framework to optimize fuel and other resources.
The flight routes of passenger aircraft are generally well established. In practice, unforeseen factors, mainly related to the weather, often force pilots to cover more kilometers than anticipated. A Polish-Colombian team of scientists and engineers, inspired by the behavior of insects and birds, has developed software that allows real-time rational modification of flight routes. As a result, it was possible to achieve measurable savings, both financial and with regard to environmental protection.
To overcome the material rigidity and actuation limitations in current robotic systems, a joint US Army Research Laboratory and University of Minnesota research project sought inspiration from invertebrates.
When tested on their knowledge of 23 types of weather information, from icing forecasts and turbulence reports to radar, 204 general aviation (GA) pilots surveyed by Embry-Riddle Aeronautical University researchers were stumped by about 42 percent of the questions. The findings, published in the April 2018 edition of the International Journal of Aerospace Psychology, are worrisome. Embry-Riddle's Elizabeth Blickensderfer said, 'We have got to improve how weather information is displayed.'
A position statement from the American Academy of Sleep Medicine (AASM) concludes that fatigue and sleepiness are inherent safety risks in the ridesharing industry.
Engineers have proposed a coordinated control architecture for motion management in advanced driver assistance systems (ADAS) to increase safety and comfort across all vehicles, regardless of ADAS specifics.
Michael 'Miki' Amitay, the James L. Decker '45 Endowed Chair in Aerospace Engineering at Rensselaer Polytechnic Institute, has received a grant from the Air Force Office of Scientific Research to study the phenomenon of flow separation on aircraft wings, which could lead to improved aerodynamic performance in future-generation air vehicles.
The shape of water. Can it tell us about what drives romance? Among fish, it might. Eva Kanso, a professor of Aerospace and Mechanical Engineering at the USC Viterbi School of Engineering studies fluid flows and almost like a forensic expert, Kanso, along with her team, is studying how aquatic signals are transported through the water.
Chemical models developed to help limit the emission of pollutants by car engines are being used to study the atmospheres of hot exoplanets orbiting close to their stars. The results of a collaboration between French astronomers and applied combustion experts will be presented by Dr Oliva Venot and Dr Eric Hébrard at the European Week of Astronomy and Space Science (EWASS) 2018 in Liverpool.
Electronic waste -- including discarded televisions, computers and mobile phones -- is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it's been unclear whether it's reasonable from an economic viewpoint. Now researchers report in ACS' journal Environmental Science & Technology that recovering gold, copper and other metals from e-waste is cheaper than obtaining these metals from mines.
