1. DESCRIPTION

gnu-A, or gnu "A", is the beginner paraglider from Laboratori d'envol. As its name suggests, the desired level of difficulty will be "A" or even "A-". The first design has been completed on February 2015, using the program LEPARAGLIDING version 2.40. Later updates in May 2019 using LEPARAGLIDING 2.96 includes mini-ribs, nylon rods, and new calage, and the design was renamed gnu-A+. Main features: 27 cells, 4.3 moderate aspect ratio, 20% thicker profile "gnuA" based on gnuLAB3 airfoil, large sizes, very stable... This wing is completely defined in digital format, in a compressed folder, which contains the subfolders “dxf” (edited CAD files), “lep” (LEPARAGLIDING files), "pre1.5" (pre-processor files, “png” (png illustrative files).

4. CONSTRUCTION

Currently, there is no prototype in 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.
