Slightly off topic, but interesting
Tests have shown that by shaping the leading edge of the wing like
this whale's flipper (Knolhval - dont know the english name),
we will get a lot more efficient wing
Note all the bumps on the leading edge!
The vortex created between the bumps makes the airflow stick to the wing much
better which has great effects.
- 8% more lift
- 32% less drag
More fuel efficient, better low speed performance, better range etc.
