Fan Car

Came across this article today, an aerial atom using high speed electric fans to produce equivalent negative lift to wings, but without the drag from the wings.

Not sure a rubber skirt being sucked down to the ground is lossless. Nor would it be legal with our 40mm ride height rule.

And imagine if the fans didn't work on a high speed corner....

I thought the fans only had to watch on the corners. I didn't realise we had to work. I thought the marshalls do that!!!

Slightly different approach to the Brabham fan car: https://m.youtube.com/watch?v=B294RfWj1QE

In Australia Malcolm Oastlers OMS is fitted with skirts, we also have the 40mm rule, he has won various championships, none of the competitors protested and the stewards never picked it up so read what you will into that.

But do the skirts remain 40mm off the deck? Or is ride height only applicable to the centre of the car?

For the fans to be more effective skirts would be needed to seal the floor to the track, skirts were banned many moons ago so I don't see this as such a good idea.

I have seen scrutineers at sprint meetings checking ride heights in the paddock. Anyone failing the initial check had to go to the certified flat area to be properly tested. A couple of Westfields failed along with some single seaters however, all were able to adjust their cars to pas the more accurate test.

The ride height is applicable over the entire under-surface of the car.

5:20:10 knocks skirts on the head.... Pity cos the 40mm rule 5:20:11 actually only applies to bodywork and the suspended part of the car... Fitting your fans and skirts to a rigid frame attached to the bottom of the uprights (not suspended) would have got round that.... Not that I think it would be a good idea but it would be fun seeing how people went about solving the engineering issues!! :-)

I asked the RAC (for the younger elements they ran motor sport in the uk before the MSA) in the late 80s/early 90s if I could attach skirts to the wishbones as they would not be part of the bodywork and the reply was something along yhr lines that they were either bodywork below 40mm or moveable aerodynamic devices in either case illegal.
