Two issues – 1) you need a shark fin to do it, shark fins are banned 2) you need an additional slot in the rear wing to do it, which is also banned.Fabi1111 wrote:Why do the cars in 2011 and maybe 2012 have no F-Duct (i mean the F-Duct from 2010, not the Front-wing-f-Duct, which is called W-Duct - i think
Okay, the FIA do changed the rules and now the driver can´t do anything with his hands, just drive, but what is with a passive F-Duct, which Mercedes had in 2010?
Okay we have DRS, but you will have a so much better straight-line-speed in the races, that must be enough to install it?
So why not?
P.S: I hope you can´t understand everything. My english isn´t so good... Sorry
How else do you duct air to the slot in the rear wing in a controlled manner?imightbewrong wrote:You don't need the shark fin.
No, this would break rule 3.10.1, as you'd get 2 cross sections in the end plate.RB7ate9 wrote:Supposedly Mercedes has some passive F-duct system (not W-duct, but an F-duct). Would it be possible to have ducts coming through the rear-wing endplates? Ejecting high energy air either above to stall or below to improve grip?
I'm not sure what this has to do with F-ducts.
Mercedes did it through the endplates of their rear wing in 2010.beelsebob wrote:How else do you duct air to the slot in the rear wing in a controlled manner?imightbewrong wrote:You don't need the shark fin.
I am trying to read the regulation and it's, naturally, a little hard to visualize. Does this mean that the cross-section must be uniform (i.e. no hollow end plates?)beelsebob wrote: No, this would break rule 3.10.1, as you'd get 2 cross sections in the end plate.
The article mentioned - briefly - allegations that there was some sort of f-duct aspect "in addition to the DRS".beelsebob wrote: I'm not sure what this has to do with F-ducts.
It means that if you take a slice through the end plate, using a vertical plane, parallel to the side of the car, you can only get one area filled in, never two. A hollow endplate would therefore be banned, because at certain slices, you get two areas – the one in front of the tube, and the one behind.RB7ate9 wrote:I am trying to read the regulation and it's, naturally, a little hard to visualize.

My bad though – I missread the rule, this one bans the slot in the rear wing, not in the end plate (it's too near to the car centre line to be the end plate)... I'm pretty sure there's another that applies to the end plate, just at the moment though, I need to head to work, sorry.RB7ate9 wrote:Thanks for the clarification. The more you know
