I don't see a sci.engr.aerospace newsgroup so I'll try here...
We have these popular aluminum wheels with as few as five column-sized
spokes and often there are six spokes or more. And sometimes the spokes are
smaller but paired together so count the pair as one...
And consider vehicles that have separate frames and fiberglass bodywork. A
steel frame is more elastic and less prone to cracking than aluminum. But
aluminum frames are sometimes used with large sections. But an aluminum
wheel is no problem since wheels are easily replaced. So the wheel is a good
place to save weight.
Now unsprung weight is also important and so aluminum wheels result in less
But here's the question. Are these aluminum wheels with column-sized
spokes...are they aerodynamic ? I mean obviously they are not but is there
more involved ? Like do these wheels create some kind of vortex that smooths
out the air flow down the side of the car ? Or are these wheels simply not
very aerodynamic in any manner ?
Well google for aerodynamic wheels and disk wheels are found for bicycles...
