Ferrari F2012

[NonNewtonic]

I think Ferrari is working something like what McLaren did to diverge the exhaust gas to the diffuser thats why the part of the floor near the rear tyres are detachable

[Owen.C93]

Agree with you owen. it would be nice to compare with some pictures form jerez lat year of the f150 to see. Surely ther could be similar light conditions and pictures at pit exit

Here's the best I could find so far, it gets a bit hard since 99% of images have the exhaust down there which obscures the floor. Here's a comparison of floors from last year as well and you can see Ferrari seems to be missing a core compared to some others.




EDIT: There's some black covers on the RW with a nice view of the exhaust here.

SO in comparison with last year it seems the thickness is the same (and the floor is less thick thatn others) whereas this year the floor indeed seems more glossy.

Could be a trick of the light, a coincidence in comparing beginning of the run in 2012 vs pit reentry in 2011, or there could be something going on with that, as scarbs suspects.

For example if ferrari are trying to send exhausts against the floor, to achieve an ebd-like effect, they "for sure" have to have heat resistant material in that zone, and maybe having as little as possible surface roughness helps, in the sense that it dampens less energy from the exhaust plume.

Last year some networks had thermocameras, especially in the pits; I fear that a thermocamera mounted on a running rail is not available (even if we have seen some running tv cameras in hockenheim iirc). It is a shame beacuse we could learn a lot.

Curious to ask but wasn't Rory Byrne working on the skirt and bottom plate of the car?

Hence possibly this new "thin" "glossy" result?

It would not surprise me if the South African master has been working as a consultant for Ferrari especially since he is Andrian Neweys kryptonite.

Lot's of weird stuff went on Friday in session 4. Alonso didn't run for hours as they fixed things and added new parts. Then the car went out for just a couple laps and that was it, Jerez was done.

You can see from the picture below the exhaust has been moved/angled differently from it's previous position. There is also the black cover over most of the bottom of the rear wing that wasn't there at any other point during testing. Also, the big one for me is there is something between the rear wing endplate & the tyre at the floor. But I don't know what and I've only seen two pictures with this configuration.




Here is another picture with the black cover that hasn't been seen anywhere expect on the last few minutes of testing day 4. Also note how little rake the car is running compared to the previous running that day and the 3 days before it. Still not sure what the black cover is. And you can't see from this angle the other side of the car where there is something between the wing & tyre.

maybe its a different addition to the bottom of the rear wing that they have bolted on

[Gridlock]

Here's a thought: the regs say you can't do anything with the exhaust gas, but could you (efficiently enough to be useful) transfer the heat from the exhaust container to the floor? Essentially a heat exchange matrix in the exhaust, some very thermally conductive material and then use the diffuser as a radiator?

I can't help but feel that given the FIA's intent of making exhausts aerodynamically neutral there is far too much speculation about exhaust treatments and not enough about how else you recover downforce / develop your car this year. Surely the engineers have spent their time on things other than trying to replicate an EBD against the FIA's express wishes.

That seems complicated and unnecessary?

[Gridlock]

Have you seen the W03 thread?

It does, I agree, but weeks of talk about Ferrari running dissipative bodywork etc combined with a shiny floor made me wonder whether this much hyped exhaust energy is worth bothering with.

I still can't even figure out the 'acer nozzles' and how they are only seen on the Ferrari if they are legal.

I seem to recall the v1 2012 exhaust treatment from the FIA was 2 straight pipes exiting behind the beam wing, but this was shot down on safety grounds? It would have made for a much simpler analysis of the cars, that's for sure.

[PlatinumZealot]

The shiny floor was on a few cars last year. Toro Rosso was one car with a thin shiny floor. Maybe they molded the floor on the top side?

[MIKEY_!]

Gridlock: We would still have all this horrible heat transfer nonsense. And engine manufacturers whining about long pipes.

That wouldn't create a flat floor from underneath though would it?

Those black areas look temporary- even taped on. I am guessing these are just barriers so that they can isolate the effect of something and that the device between the wing and the wheel is a sensor.
They seem to be messing with their exhaust configuration and they may want to see the effects on the diffuser separately from the effect on the air around the wheels, or something like that.

[Shrieker]

I concur, they might be using a -not necessarily race legal- part to seal the diffuser which they might be trying to achieve with the exhaust flow but not successful yet.

[bhall]

I think those pictures make it quite obvious that Ferrari haven't many ideas yet about the effects of their exhaust configuration. They're burning bodywork and putting up heat shields everywhere.

I'm most taken, however, with the low, low ride height at the rear of the car.
