1. Description
Figure 1. GNUA13 3D view generated by lep-3.19
GNUA13 is a mini paraglider "speedglider" with 25 cells
and 13 m2 of flat surface.
This prototype was started to built in Mars 2022 by Marcello Gabrielli in Cagliari, Sardinia (Italy)
This will be the fourth prototype of this model, originally designed and built by Eric Fontaine (Tarnos,
France),
made later by Oleg Egorov (Minsk,
Belarus), and later by Thierry Bosq (France)

4. Some pictures and videos of the
construction:
Video: Destructive test of an anchor. Of course, the procedure is not very "scientific",
but it is used to perform various sewing tests and verify that the system is working properly.
In this case the device broke below 75 kg. This paraglider uses full diagonals right and left,
then the maximum load will be even higher
We will add more details soon

Note: This wing flies and lands at high speed. It is necessary to be
careful and use the appropriate technique, especially at high altitude
and with weak winds.
