Ferrari F2012

[McMrocks]

one question to the experts:

is the internal airflow good when the air can go fast through the car?

so this means if there is a big slot in the engine cover a car is faster on straigt?

We haven't seen any pictures with the Sauber sidepod inlet completely removed, but I assume it looks much like this.

From pics we have seen i think Sauber radiators are bigger, less tick, and less dense than Ferrari.

Ferrari geniuses? If anything, sir, I think 2012 has taught us that such individuals aren't to be found anywhere. They've gone the way of the dodo bird. But, I welcome the addition of your delusions to the collective, nonetheless. Sometimes that's all we have to keep us going.

EDIT: Unrelated, but, for the love of Jah, why can no one see the lift potential in these Bernoulli playgrounds that Ferrari calls sidepods?


(Click to enlarge, at your own risk. And don't judge my artistic abilities.)

To me, the problem is still there. Poor extraction from that area. We have all seen aerovis photos of that zone, there's no flux at all. Sidepods cannot extract anything to feed the diffuser, add some lifting effect and there you are.

And yet with all this talk of exhausts, it doesn't seem clear to me that there's really that much benefit being gained by teams because of their exhaust positioning. [...]

I think the irony of this whole ordeal is that it seems Ferrari would have done themselves a huge favor had they stuck to their bread and butter design philosophy of expertly refining conventional wisdom, something no team does better. The regulations appear to be tailor-made for that kind of approach.

The week before the Chinese GP I thought about that. Looking at the successful designs this year and knowing the time performances of the F150, a car that could not benefit from a lot of EBD performance... the irony was pretty obvious.

If Ferrari had had a more conventional approach switching to pull rod given time, step by step... they could by now being at the front of both championships.

But sometimes a organizations are not rational. And there's also the pressing need of adaptation that couldn't be posponed any more.

You will note from other radiator system photos that the volume of the cooling duct expands before reaching the radiator. This slows the flow and increases the pressure.

Wait, if its expanding, shouldn't it speed up the flow and reduce pressure as a result?

no...its exactly the opposite..it will speed up flow only on the intake..

If the flow was supersonic, then yes. But in this case it is clearly low subsonic, so expanding the flow does indeed reduce its velocity and increase its pressure. Think of it as the 'second half' of a venturi tube, where the flow expands back to its initial volume and sees a corresponding decrease in velocity, and increase in pressure.

ok, that makes sense, thanks fro the clarification.

So what us being said here is the observations made by many in this group are collectively smarter than the aero guys at Ferrari with all the data in front if them? With all due respect, I find that hard to believe. It can't be that simple.

Basically this is how people see ferrari now so...

Scarbs saying now on the flying lap that the main problem ferrari has is pitch sensitivity...as the car is braking and accelerating and the angle of the car changes the downforce is shifting a lot...and this is linked to the front wing....

im thinking also, that they possibly had a reactive ride height system??

EDIT: i asked the question now...lets see if its answered..

Reactive ride height suspension is banned, so it is highly unlikely!

Indeed however when Ferrari were developing their car over the winter, it was legal and could've been incorporated into their car. Could possibly be one of the reasons they're suffering.
Yes this is a rumor, but it comes from Spanish media sources, which of course have ties into the team.

we are saying the same thing...im thinking that if they had a reactive ride height system...which would sort out the pitch sensitivity..the fact that it was banned harmed them...
