LEparagliding Studio 0.1.0 — first public release.

A Qt 6 / Open CASCADE desktop port of Pere Casellas' LEparagliding 3.28 "Jardins" paraglider design program (GPL-3.0): the complete calculation engine, mechanically translated from Fortran and validated byte-for-byte against the original, wrapped in a modern design studio — with a full XFLR5 integrated for aerodynamic analysis of the wing you are designing.

Highlights

  • Integrated XFLR5 — the complete XFLR5 v6.62 runs inside the application as an Aerodynamics tab, and the calculated wing is transferred to it automatically: design the glider and analyze its aerodynamics in one program, with no export/import round-trip.
  • Full LEparagliding 3.28 compatibility — existing design files work unchanged, and 3.17 designs that end at section 32 load with disabled defaults for the newer sections. The original design file is never rewritten.
  • Design studio — every input section has its own syntax-highlighted editor with independent undo/redo; each Save embeds the complete whole-wing version history in the design file, so any earlier state can be restored later.
  • Exact 3D model — the wing is rebuilt as exact rational B-spline surfaces with Open CASCADE and exported as an AP242 STEP assembly (named panels, ribs with cut-out holes, diagonals, and suspension lines tagged with their section-34 line types), alongside the classic DXF plans, line reports, STL and XFLR5 outputs.
  • Presets — wing designs from laboratoridenvol.com ship with the app and calculate out of the box.
  • Validated numerics — against native gfortran output: both DXFs, lines.txt, and run-log.txt match byte-for-byte; the calculation report matches field-by-field.
