Wisdom of Shark Design

Denticles for Less Drag and More Lift

Using shark scales to design better drones, planes, and wind turbines,
Harvard John A. Paulson School of Engineering and Applied Sciences, February 6, 2018.

"The skin of sharks is covered by thousands and thousands of small scales, or denticles, which vary in shape and size around the body."

"We asked, what if instead of mainly reducing drag, these particular shapes were actually better suited for increasing lift."

"...in addition to reducing drag, the denticle-shaped structures significantly increased lift, acting as high-powered, low-profile vortex generators."

"These shark-inspired vortex generators achieve lift-to-drag ratio improvements of up to 323 percent compared to an airfoil without vortex generators."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
