1. We already know about tripping boundary layer turbulence to prevent on the onset of separation which both lowers lift and increases drag.

2. A wing designed to function like a whale may be good for very low speed incompressible flow wings. Unfortunately all commercial aircraft fly in a faster flow regime.

3. Why are we surprised that a creature that lives in the water has a body designed for swimming in water?

Plagiarizing old stuff for grant money

This is old stuff. My father, an old time aerodynamist was one of the 2 original founders of the American Helicopter Society with 80 patents, (He worked with Igor Sikorsky, Stan hiller, frank paisecki and even spent time with Charles Lindbergh) sat next to a guy at Aerojet in the 50's who invented Vortex generators, those little tabs you see on the leading edge on the wings of commercial aircraft. Does the same thing.

I do like the bumps on the whales nose, should try that one on a sub
