Watch This Material Morph Itself To Become More Aerodynamic
Researchers at MIT have developed a smart curved surface that can morph at will to reduce drag, generating a series of small, evenly spaced dimples that make it resemble the outside of a golf ball. This technology could be used to reduce hurricane damage on some public buildings, as well as increase the aerodynamic and fuel efficiency in cars.
Scientists and golfers alike have long known that the dimples on the surface of a golf ball allow it to drastically reduce drag and travel much farther than would otherwise be possible. This happens because the small dents hold the airflow near the surface of ball for a longer time, and this reduces the size of the wake, or zone of turbulence, as the ball takes off.
