gnu-A^{2}, or gnu "A^{2}", is the new Laboratori paraglider project started September 2016. Of course, is the successor of the gnu-A.

Wing using the same geometry that gnu-A, but with the following changes:

- 28 cells (instead of 27)

- Internal structure of diagonal ribs "type-3", this simplifies the lines.

- Miribs in leading edge

- Simplified brakes

- 4 risers (instead of 3), for more groundhandling control

- Planned sizes 27/25/23/21 m2, starting whith the 25 m2 "M" size

Recommended materials:

Extrados 35 gr/m2

Intrados 35 gr/m2

Ribs and diagonals 35 gr/m2 hard finish

Lower lines: Sheated dyneema > 250 Kg

Upper lines: Sheated dyneema > 160 Kg

Main brake line: Sheated dynema 275 Kg

Nylon rods: 2.7 mm

Semicircular adhesive reinforcements: Polyester 80 gr/m2

Trailing edge 20 mm mylar galon

Data input files: pre-data.txt leparagliding.txt gnua.txt gnuat.txt

Output files: lep-out.txt lines.txt

CAD DXF2000 files: gnuA2-2D.dxf gnuA2-3D.dxf

Is planned drawing soon more detailed plans, including the line labels, LE rods, and other important details.

As always, the plans are delivered free ("of freedom") to be studied and copied for any purpose, to make a prototype, or even serial units. You may copy the design, improve it (or not), change the colors and/or the name, suited to your tastes.

This glider, is the one that I would fly at this time!
