Aerodynamic study of suv/trailers

I’ve enjoyed going through this material so I thought I’d put it here in case others haven’t seen it yet. It was of particular interest to me and has influenced my thoughts on trailer designs.

It is pretty thorough. The emphasis is on drag, the one picture of the crosswind streamlines points to a different consideration.

I'm pretty confident someone with more chops than me can take free and open source Blender software and produce state of the art CFD animations. It's above my pay grade. The competiton would be the Unreal Five engine. Best I've been able to do in Blender was this:



Those 'streamlines' should be able to flutter in any breeze. Mine are definitely low-poly.

#3 is going to take some time.

But then they did start the curve a few inches (else mm) below the tops of the windows. Vortex generators.

The recessed awning struts are a nice feature.

He found some aspect to get a patent on?

Perhaps they aren't checking carefully down at the patent office. Except for the wheel well covers, and flush awning, not too much that is special. Im not a fan of having your propane inside, and the bathroom could be better thought out.
