NASA is using the Internet to show students and the general public what airplane designers do. The agency has created an electronic site, called Aero Design Team Online, at http://quest.arc.nasa.gov/ano/index-new.html. There NASA demonstrates how aeronautical engineers use airplane models, wind tunnels, supercomputers, simulators, and other tools during the airplane design cycle. The project continues through May, although plans are underway to extend it into summer. "We're teaching about airplane design through the lives of people who are doing the work," says Susan Lee of NASA's Ames Research Center, Moffett Field, CA. "For example, we're following a wind tunnel test of a model of a future supersonic airliner," she explains. Students can ask questions through e-mail and participate in Internet chats with engineers from teams that design and test airplanes. An aim of Aero Design Team Online is to inspire students to pursue high-tech careers.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
