@JS_Brouillon , thank you for this document.
Remarks on formal details concerning the numbering: from 500 in figure 5, from 600 in figure 6 (which is normal) but respectively from 900 and 1000 in the description on pages 14 and 15 for the same figures 5 and 6, so that for example the element 901 described on page 14 for figure 5 is assigned to another element and another figure (figure 9).
Please what is the meaning of the term “elevons” on page 17? Ailerons? Elevators?
Basically, although they are described, it is difficult to identify the essential elements which define the new solution in relation to the state of the art in spite of the quoted prior art. However the new solution appears very well on the video (fixed bridle and the means for a rotation in extension).
For example the “fairings” are not specific to the invention even it uses them. Perhaps a first draft of the claims would make it possible to better highlight what is new.
The title itself “Scalable and controllable airborne wind energy systems” does not allow to direct towards the main specificity. Perhaps something like “Scalable rotating airborne wind energy systems with simplified control”, then quickly in the description disclosing the means (fixed bridle, increase of the swept area by using the extension of the lateral tether using centrifugal force).
You have to wait for Figure 6 to see the new elements as they appear in the video. Figures 1, 2 and 3 and corresponding texts describe elements which appear to be part of the state of the art, except for elements justified by equations, but which would then find a better place in the dependent claims (other than the first claim).
Apart from that, as a curiosity, we can see something apparently similar, but only in appearance. We do find the extendable side tether, but in this case it is used for power take-off (PTO).
Stretch kites,
