Isotropic Kite in Persistent Flight
The World Kite Museum's Indoor Kite Festival took place last weekend. KiteLab Ilwaco once
again performed a public first demonstration of
a key proof-of-concept prototype. Last year it was shown that an
anisotropic (weathercocking) kite can be
maintained aloft in calm wind by phased tugs from three fixed anchor
points. This years demo was not quite so fundamental, but still portentous.
It was briefly shown (at the end of the event) that an isotropic kite
can also maintain flight by phased tugs (a radially symmetric Sedgewick
U-FO offered by Joe Hadzicki's Revolution
brand). The significance of this proof is that future megascale arrays can accept
wind from any quarter without having to spin, but merely tilt from
veering wind in real time.
The three pilots this year were Scott Davis, the founder of the
festival, a small kid-star competitor named Ian, and the I-Quad
star founder John Barresi.
John was very intensely focused on the optimization of this concept.
We concur that the flat kite tends to track horizontal and even dig
down, so it needs a bit of reflex in the next iteration to improve the
flight dynamics. A simple bridle refinement will do. Full-scale soft
arrays will require further design refinements, but we are optimistic of
the practicality of the general concept space
