Shark Scales Inspire Faster Aircraft

A material inspired by the unique surface of shark scales could lead to faster aircraft.

While studying the shortfin mako shark—one of the fastest sharks—the team from the University of Alabama discovered that the shark’s scale will flex upward up to 40 degrees. This angle prevents the eddies that cause flow separation and drag, allowing the shark to move faster in the water.

The team believes the same technology could be applied to the surface of aircraft or helicopters. According to aeronautical engineer Amy Lang, "The potential for a man-made surface to utilize this entirely passive mechanism even in air is very exciting."
