Define this theory please, as well as the following statements from “Kite scaling” to “kite scaling”.
Markus Sommefeld has left no stone upturned. His scaling analysis perfectly stands. The wingspan and the mass are enough to establish the scalability, whatever the wings, flexible or rigid, and their aspect ratio.
As I mentioned, exponent K = 1.3 cannot stand with the exponents K = 2.7, 3, and 3.3 given by the author.
The square–cube law (or cube–square law ) is a mathematical principle, applied in a variety of scientific fields, which describes the relationship between the volume and the surface area as a shape’s size increases or decreases. It was first described in 1638 by Galileo Galilei in his Two New Sciences as the “…ratio of two volumes is greater than the ratio of their surfaces”.[1]
To put it simply, the square law leads to an exponent K = 2 (area), while the cube law leads to an exponent = (more or less in practice) 3 (volume). As a result your 1.3 is a nonsense beside 2.7, 3, and 3.3 given by the author.
Just below is a sketch (from the figure 3), adding scaling of a soft kite by the square law (K = 2), so by keeping the same weight / area ratio whatever the kite size:
