According to the video, the development work is open source and available at: https://gitlab.com/HG-dev.

For anyone not familiar with downloading from GitLab, I've attached a ZIP file below of the current version. To save space, this ZIP file contains only the current version (28.6 MB) and does not include the GIT history. The full version (with GIT history) is 95.8 MB, and can be downloaded from the GitLab repository mentioned above.

I am not familiar with the tools they are using, and I haven't looked closely at the data files yet. But I believe they are using open source tools that can be downloaded per their instructions. I've just done a quick scan and the required software seems to include:

  • FreeCAD and sail-making macros
  • OpenVSP with the API installed
  • Jupyter Lab or Notebook with the VSP kernel accessible
  • InfluxDB database
  • Open Modelica

I dug through some of the files and found these airfoil cross-section files:

aerodynamic-modelling/data/aerofoils/ui1720reflex.csv
aerodynamic-modelling/data/aerofoils/ui1720mod.csv
aerodynamic-modelling/data/aerofoils/2R15section.csv
aerodynamic-modelling/data/aerofoils/tipsection.csv


I wrote a quick plotting program (in Python/TKinter) to display them:
