From Aircraft Modeling with FreeCAD to Flight Simulation Addon

This is what I've made last few years. As a result, I made an addon for commercial flight simulation software (I'm using MSFS in this case but I also checked this can be done with DCS World) almost completely with open-source softwares, such as FreeCAD, Blender, GIMP, OpenFOAM, Octave, Inkscape and LibreCAD.

Actually my first goal is not here. I just wanted to conduct my own CFD simulation but I don't have much money to get commercial CAD and CFD softwares. Thus I made aircraft 3D model with FreeCAD and conducted CFD with OpenFOAM. I say, you can make aircrafts with FreeCAD, but it is more difficult than using other commercial CAD softwares. FreeCAD is a brilliant software as it is now, but I think that it still have a long way to go. I'm awaiting new features and fixes from many talented and dedicated developers after its official 1.0 release.

Is there any other aircraft modeling examples? I want to learn advanced workflows about surface modeling with FreeCAD for aircrafts.

No idea about Aircraft modelling, but this looks cool 8-)

Thanks for posting this, cool work.
I like the sound of the motor/prop.. :)

I found this process of creating a model and inserting it into a simulation program interesting. If you could explain it to us a little more that would be great.

Just to remember, it is also possible to animate and render in FC. ;)
