gnuPSF Parafoil Simple Face

gnuPSF (gnu Parafoil Simple Face) is an easy rectangular single skin paraglider. Inspired in the small PSF, but modified in aspect ratio, panels , lines, and scaled to 18.75 m2. But a rectangular single skin wing, can work? In theory not much... But in practice, it looks like it might work... Do not expect that once the construction is finished this design fly properly. Corners of the leading edge, calage, and tension in trailing edge can cause problems in the first prototype.

2. LEparagliding data Files, output files DXF Plans.

Available in two versions (updates 2017-06-18)

A) "Pure ss version":

Pre-processor: pre-data.txt geometry-out.txt

LEparagliding: leparagliding.txt gnuPSF.txt lep-out.txt lines.txt

All DXF plans, lep, and PDF here

PDF plans and A4 templates here

B) "Tube version" uses one central tube. All files here (lep, dxf, pdf)

Notes: 1) gnuPSF airfoil, now, is identical to the bhl2 airfoil, but a new profile can be studied.

2) Of course, this design requires only one template for the profiles, and one template for the panels :)
