Just a sample of interesting side suckers at Frankfurt Auto Show.

I might have to admit this stuff works, at least in selling cars.

I'm cross-linking to another thread (not my work) I've been posting in for a few weeks. You guys might find this project of special interest, and the comment made of some value. You may have to sign-up to see some of the images, sorry about that.

Not every side-mounted airscoop develops into an air curtain.

I have to agree, that sample I came up with, well the last two samples just seem to capitalize on the twin/split radiator look of water cooled Porsche's and Ferrari's and have little to do with an air-curtain.

My other hobby is hovercraft, and early hovercraft used an "air curtain" to contain the cushion or bubble of lift air under the hovercraft hull. In that context, I have to ask what's next? A blower fan blowing pressurized air over the wheel wells?

That idea is not so crazy, NASA has a few illustrations of helicopter, propeller and fan blades with pressurized air flow. The intent in those examples is to lower the overall sound levels caused by turbulence.

Well racers have had blowers before (old posting I know)





Slightly OT - what about Ground Effect which was used in F1 for a few years (until banned).



You would need variable ride height though, maybe ? Just a though.

Don't laugh too loudly about fans. Morelli et al realized a 5kW reduction in power required for an expenditure of 240W by putting inward drawing fans in rear wheel covers. (Admittedly with some fancy ductwork too)

On public streets ?

The average pothole is way deeper than the almost non-existant ride height .

Down-force and collecting air at the sides.

I think this was for down force right?
I believe taking air out from under the car creates better down force.

Only useful on motorways which tend to be smoother - but then again I buckled my wheel last year on the M8...
