Why Elasticity is The Key To Flapping Flight

From Technology Review published by MIT...

"Flap your arms for a while and you'll soon notice that the constant cycle of acceleration and deceleration requires and even wastes huge amounts of energy. And yet for birds, wing flapping is a highly efficient means of propulsion. A questions that still puzzles aerodynamicists is how birds are able to minimise the energy costs involved in flight while generating useful aerodynamic forces."

  1. Very interesting article.

    It's amazing how complicated it is to reverse engineer natural phenomena, when nature itself can easily develop such interesting mechanisms.
