I'm looking at this stuff and thinking those teeth would work on the leading edge.
The way I understand the
effects, is you can get a much higher
AOA before stalling the wing (whale fin).
I've been thinking about adding a sawtooth leading edge to one of my
Coroplas model airplanes to test out the AOA idea..
This type of pizza box wing design really doesn't have real lift, but is fun to
fly around real slow angled up about 45 degrees. (A good engine is a must).
I suspect that adding
Whale Tech to the LE will improve the high AOA slow speed hovering ability a lot..
Now, I just have to figure out how to implement the idea..
