What means WIPIKA ?

First was the WIPICAT for P.ropelled I.nflatable CAT.amaran
Then we decided to call the wing WIPIKA, just to make it sound right.
That can mean WI.nd P.owered I.nflatable K.ite A.ircraft or something else.

Why this design?

First were two wing types known for their efficiency :
-  the soft wing patented by Rogallo which first gave the Nasa-wing type then the deltaplanes/hang-gliders and stunt kites
-  the multicell airfoil patented by Jalbert which gave the cellular parachutes, paragliders and parakites.
New airfoils partly based on these two inventions appeared (Flexifoil, banshee...) and continue to do so.
All these wings use multi-line bridles and/or air cells and/or rigid spars.
Generally they can not be reasonably used on the water for safety reasons: when they fall, it is difficult or impossible to relaunch them.

The Legaignoux's design now appears to be the third efficient type of airfoil. It has no multi-line bridle, no air cells and no rigid spars. It was designed and improved with one main goal: ease of use. 
Easily relaunched thanks to its inflatable frame and its 3D shape it has other advantages which make it competitive with parakites and deltakites on sand, snow, ice....
This invention is protected by an international patent.
