ALT-AIR Accuracy

1. Description

Accuracy is a new paraglider designed by Paweł Lipski and Bogusław Pelczar from Altair Paragliders in Poland. The design has been made using the latest version of LEparagliding (3.10). Although the geometry of the glider and the number of cells is moderate, this paraglider incorporates numerous advanced features, among others:

- Shark nose airfoil
- 3D-shaping (using 3 different groups)
- 3D printed rods at the leading edge
- Wind flap near trailing edge
- Vortex generation on the top surface
- Improved skin tension (uses module new skin tension in 12 groups)
- V-H ribs type 1,2,6

The name of the wing does honor to the accuracy of its design, therefore it has been used a profile with 286 points, 3 different grups of 3D-shaping, and 12 different groups of skin tension with 24 points of control in each group.

"The wing flies very steadily. Easily gets up above our head. And lands quite softly. It looks well balanced.
We didn't check the speed. These are the first impressions of the first flight."
