Ridges On Whale Flippers

May 29, 2011 27 Replies

The suspension ropes distort the airfoil where they attach. This might be engineered to whale flipper specs to provide more maneuverability.

No, the flight recorder data is indicating the pilots added nose up input. and the plane stalled out and basically feel out of the sky at very high AoA.

Yeah, right.What does a deflected slat have to do with the local sweep angle of the leading edge?

Stall wouldn't have happened with whale ridges on the wings.

Separation => stall. Whale ridges eliminate separation even at high AoA.

That's why whale ridged fans only need 1/2 the number of blades, axial compressors 1/2 the number of stages. The high AoA is 2X.

Based on what specific data?

Again specifically how does this apply to the specific situation? Cite specific AoA in both incidences please. Not generalities.

Fascinating, I love these types of stories. As the story said, most people would've assumed that these bumps should go on the back of the wing, not on the front.

It would be difficult to compete against a whale flipper article.

This also has some application making other wise boxy shapes that a suitable in real life city traffic more aerodynamic.
