Technical Regulations for 2009-2015

[Holm86]

They did mention fan cars. And yes I would also say fan cars are ground effect cars.

A fan car makes sense as it doesn't get interrupted by the wake of the other cars. So it would be much easier to follow the car in front which is what the OWG wanted.

Where it doesn't make sense is that is sucks a lot of debris from the track, throwing it directly at the car behind. And that's not safe.

A fan car does not have to link the fan with ground effect but I won't go too far into that.

Blown aerodynamics are not restricted to ground effects and to have good drag characteristics you need to have a close to freestream flow velocity at the back of the car so a fan doesn't really throw things.

But it is the first time i hear about that fan car thing. There were plans for ground effects cars in 2011 with 2014 planned introduction but there were no words about fan cars back then.


If someone has a subscription to Autosport plus maybe he can throws some clues about that?

They didn't really go into detail about using fans, but here's the part where it's mentioned.

Thank you very much. I wasn't aware of that and IMHO it has never been publicied.

No problem. Here is the article in it's entirety. It's all about technical regs and loopholes so it fits in this thread well. Cheers.

I know its not restricted to ground effects. But in the spoken case I would say it is.

And I seem to remember that other drivers were complaining about the Brabham BT46B throwing debris around.

As far as I remember, the 2008 cars generated around 2,700 kilograms of downforce. If in 2009 simulations technicians estimated that reducing the amount of downforce by 50% would result in cars no slower than five seconds, one could really doubt the need for downforce in Formula 1.

[SectorOne]

A spec floor with a fan and no wings on the car at all would be sweet.
Cars would look like streamlined ultra-low-drag Salt Flat Bonneville machines and still retain the cornering speeds with the addition of perhaps slow corners.

[autogyro]

It was Max Mosley who pushed for a 50% reduction in downforce.
If this had been done, F1 would not now be entering an era where it will have to fight for its existence.

Cannot agree more.

Lower the downforce and get sticky durable tyres back on the cars, the racing to a laptime to preserve the tyres will be the death of F1.

[Owen.C93]

Weight distribution will vary from 45.5% to 46.5% assuming they meet the minimum weight.

"The weight of the car, without fuel, must not be less than 690 kg at all times during the Event."

"For 2014 only, the weight applied on the front and rear wheels must not be less than 314kg and 369kg respectively at all times during the qualifying practice session."

Scarbs analysis of new wind tunnel restrictions

[Owen.C93]

Mike Elliot spoke about this a few weeks ago, I didn't realise it wasn't in the rules yet. He said the amount of runs allowed is more damaging than the wind on restriction. For Mercedes at least.

[KeiKo403]

Not sure if this can be done or if it will even be legal but will teams be able to develop wheels to draw air through them from outside to inside and blow the air into the gap between the inside of the rear wheels and the edge of the floor....like sealing the diffuser?

Couldn't see any other thread to ask this in.
