Aerospace Engineering and Mechanics

Dr. Amy Lang works in the field of experimental fluid dynamics with a focus on bio-inspired flow control. She has discovered a passive, flow actuated mechanism for separation control due to the flexible nature of shortifn mako shark scales. Other research has looked at the micro-ridges of dolphin skin for separation control and the aerodynamic benefit… Read more about Dr. Amy W.

In The News: The speedy secret of shark skin

Shortfin mako sharks are the cheetahs of the open ocean, with some estimates putting their top speeds at more than 100 km/hr. That swiftness may be the result of more than just powerful muscles and a streamlined shape. All sharks have enamel-coated scales, known as dermal denticles, that resemble tiny… Read more

In The News: Five Scientific Findings That Could Lead to New Inventions

While new technology can sometimes feel strange, almost other-worldly at first, the future of innovation actually involves researchers better understanding the natural world around us. And inventors are catching on, with more and more embracing biomimicry, or the process of designing products to function as animals and plants do after… Read more

In The News: Scaly wings help these butterflies soar

NEW ORLEANS, LOUISIANA—Aerospace engineers are always on the lookout for ways to make flying more efficient. Now, they’ve discovered a trick from nature that can do just that: the scales on butterfly wings. Those incredibly tiny scales—about 0.1 millimeter long—are arranged like roof shingles on the wing, making it a… Read more

Graduate Student Wins Poster Contest

Sashank Gautam, a graduate student in The University of Alabama Department of Aerospace Engineering and Mechanics, placed first in a student poster contest at an industry conference in November. Gautam’s poster, “An experimental study of low Re cavity vortex formation embedded in a laminar boundary layer,” was the top winner… Read more

In The News: UA Engineer studies shark skin to help in aerospace design

The Mako shark is fast. Amy Lang, an aerospace engineer at The University of Alabama, says that’s partly because its streamlined shape cuts through the water, but it has  a big assist from the shark’s scaly skin. Lang says such a mechanism may also help aircraft surfaces. Read more
