"Whales And Dolphins Influence New Wind Turbine Design" vs leading

by =?ISO-8859-1?Q?Glenn_M=F8ller-Holst?= <nomail@[EMAIL PROTECTED] > Jul 8, 2008 at 02:54 PM

Hi!

Does anyone know how to compute how much better a airplane wing design 
based on this whale flippers shape? Is it 10, 20 og 50% better? Can 
anybody model it?:

Quote: "...
The shape of whale flippers with one bumpy edge has inspired the 
creation of a completely novel design for wind turbine blades. This 
design has been shown to be more efficient and also quieter, but defies 
traditional engineering theories.
....
The lesson from biomimicry is that unsteady flow and complex shapes can 
increase lift, reduce drag and delay 'stall', a dramatic and abrupt loss 
of lift, beyond what existing engineered systems can accomplish," Dr 
Fish advises.
...."


How does it compare to leading edge slots?:
