How Dragons Fly: When Biology Trumps Physics – Applaudience – Mediumhttps://medium.com/applaudience/how-dragons-fly-when-biology-trumps-physics-ca1f3036ed7cThe larger an animal grows, its wing area (as a flat surface) increases with the square of the animal’s length. Growing a creature n times longer would result in an n^2 increase in wing area. But the animal’s mass is different; assuming density doesn’t change, scaling mass is equivalent to scaling volume, which is a cubic relationship. The animal that’s now n times as long would be n^3 times as heavy. This is known as the square-cube law. This is where our “theoretical flight limit” becomes relevant.
