1. DESCRIPTION

Stork is the new design of Arnaud Martinez. An 18 m2 high aspect ratio (8.0) single skin paraglider, authentic three-liner, with diagonal triangles, and a reduced total line length (approximately 211 m). In order to design this paraglider, the LEparagliding program had to be modified to be able to freely rotate the planes of the profiles in three axes X, Y, Z and thus be able to align the profiles with the gliding trajectory. Here you can read some of the studies on the Stork profile and the basic ideas of the new design. And here the mathematical and geometric aspects related to the rotation of the profiles in three axes for their alignment with the flow.

In the words of the designer:

“The glide ratio should be excellent, and at very low speed so really ideal for exploiting low lift and slope flying in very light conditions. I think this is the realm of monosurfaces. And it's not desirable to make them go faster, because the parasitic drag of the lines and triangles massacre performance with the square of speed.

The idea is to still be able to accelerate Stork quite hard, for the sake of safety, at the cost of glide (high drag of a monosurface). So fly royally high and slowly in trim and get a more modest glide at 40 + km / h full bar for safety.

The goal of Stork is to make a high performance and safe slow-flyer ... "

4. CONSTRUCTION


LAB NOTE: Build a paraglider at home is a very complicated task (even simple skin), and requires many hours of work. Previous experience is required, and very inventive. As always remember that: The free flight implies risks that can only be known and they can be controled with a suitable formation on the part of a recognized school. Not test wings without knowing their functioning. The construction and test of experimental wings without certifying requires deep knowledge of what is being made.
