Parafoil Simple Face Evolution

gonflage-1
Test 1, Alibaug (India) September 1, 2020

gnuPSF-evo (gnu Parafoil Simple Face Evo) is an evolution of the experimental rectangular single skin paraglider GNU19. The concept GNU19 flies, but the instability of the front corners of the wing does not allow a regular use, different from the experimental one. That is why the constructor of GNU19, after performing different experiments and modifications, proposes to eliminate some of the external panels and replace them with others with curved shapes.

Laxman Rawat from India, modified the scale of the GNU-PSF-evo paraglider, to make a "kite" version of 10 m2. Linear scale factor to convert size 19 to 10: K=0.7 This project shows that it is relatively easy to change the scale of any wing just by applying a linear scale factor to the planes (and a bit of CAD work). Read more about scale changes. It also demonstrates the viability of the gnuPSF-evo project. Because a larger wing would be suitable for flying.

LAB NOTE: Build a paraglider at home is a very complicated task , 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.
