Ribbon-Arch Ladder Concept
The Ribbon Arch
has been an astounding curiosity, not fitting any well known aeronautical
model. Along with the "flip kite", its been claimed as simply a Magnus
Effect toy, but it was pointed out on the Forum that these kites use true
airfoils to perform tight backwards loops. This more qualifies as Dynamic
Soaring than Magnus skin-friction-dependent effect observed in spinning
bluff-bodies. A neat prediction is a low-pressure vortex inside the loop
balanced by the centrifugal force of the looping wing mass.
Comment and development of this topic will be occurring here.

(Legal Note: Open AWE CC sharing and claims rest on "artist's moral rights", under the Berne Convention. Inventing is a true creative Art, by long tradition. The intent in Open AWE is to make the widely emerging new form of CC IP voluntarily accepted and fairly valued, as AWE's professional best-practice standard. Comments invited.)

so now we are integrated with the latest standard cooperative IP model, but "coolIP" remains a nice shorthand.
