HYDRODYNAMIC FIN BUMPS
Humpback whales have bumps on
their fins. This design feature has
been found to increase fin efficiency.
When the bump
design is copied,
Manmade blades
are:
1. more powerful
2. More efficient
3. Faster
4. Have less drag
5. Work well even
when turning
slowly.
Manmade copies of
whale bump design
are 20% better than
flat blades.
