Bumpy Flying
Article Abstract:
Hydrodynamics specialist Frank E. Fish has applied specific characteristics of whale flippers to mechanical aerodynamic designs to improve functional performance. The traits consist of leading-edge tubercles, or evenly spaced bumps, that boost momentum within the fluid flow. Applications include ship rudders, helicopter rotors, and aircraft wings and propellers.
