El BarretinaHyperLite alemany

El BarretinaHyperLite construït a Alemanya s'alça de terra per primer cop:

"The wing inflates perfectly, and rises over my head,
where i stoped it with a small break input.."

"Even in almost no wind the wing stayed over my head,
then i turned around and walked a few steps
and i could feel the lift of the wing,.."

Nou pont sobre la Muga

Avui he visitat el nou pont sobre la Muga. Una calaix mixt acer-formigó en biga continua de tres vànols de secció constant i directriu recta. Molt elegant, vola sobre la Muga poc abans d'arribar a Les Escaules. Sense cap ornament que sobri (més aviat buneres, drenatges, i boques d'home)  compleix perfectament la seva funció passant desapercebut. Dóna continuïtat a la carretera GIV-5041 al seu punt quilomètric 2+500, i per sota la Muga i el camí natural del seu marge esquerre.

gnuLAB3

A new dream begins... The name is gnuLAB3. A small gnuLAB2 evolution. Possibly same planform, and the same or close aspect ratio. Cells number increased to 31 or 33, is sufficient. A new gnu airfoil, faster and more stable... A behavior objective EN-A. It is difficult to meet the EN-A requirements..., but we have to be as close as possible. Lower surface, as light as possible... Nylon rods in the leading edge work great. Maybe still 4 risers, to facilitate work and play on ground handling. It also facilitates the use of speed system or trimers.

The dream includes the possibility that a manufacturer wants to put it into production, even keeping 100% the GNU concept of freedom, plans free for copying, and modifications included. From here I appeal to any manufacturer who wants to help me build and tune this new project.

Also, if the gnuLAB2 was the mold of the simple surface BarretinaHyperLite (same basic geometry but different profile), the gnuLAB3 will be the mold for the BarretinaHyperLite2.
