Welcome to the forum @MarcoGhiva ,
Morphing kite wing looks to be a very interesting topic.
I can’t download the images. Could you please attach them directly?
Below is a description of a sort of morphing kite using a leading edge inflatable wing.
All these wings could be suitable to mitigate the energy consumed during reel-in depower phase, for yo-yo (kite-reeling, or bounding) mode.
