If the average person was asked to think of ways that future airplanes could be improved, “making them more fish-like” probably isn’t going to be among the top suggestions. But if researchers from City, University of London are correct, this could be one of the best decisions aircraft manufacturers could make.
In a new study, involving researchers from City and Germany’s University of Stuttgart, investigators set out to explore how fish-inspired scales could be used to improve the aerodynamics of aircraft by reducing drag. This, in turn, would mean faster aircraft speeds and less fuel consumption.
“We investigated how the surface of fish, with patterns of overlapping scales, [are used as] a means of reducing the drag of the fish body,” Professor Christoph Bruecker, City’s Royal Academy of Engineering Research Chair in Nature-Inspired Sensing and Flow Control for Sustainable Transport, told Digital Trends. “The scales seemingly reduce
Amazon One means you may not need a credit card or even a smartphone to pay for what you buy.
New Amazon technology, introduced at two Amazon Go stores this week, lets shoppers pay for purchases by holding their hands over a scanner. The system, called Amazon One, may herald a new way of identifying yourself and paying for things that could change the way people shop, enter concerts, use public transportation, and many other things.
