Ferrari 150° Italia

Ok, so if some other team asks for it the wing will be checked tomorrow morning.

A scarbs tweet says it has alredy been tested and it's legal.

[imightbewrong]

the wing started vibrating only under breaking. So, maybe it is a side effect of the vibrations? Whatever it is, it is clearly vibrating and flexing too much.

Nope, check the rear wing, it closes once he hits the brakes. It vibrates a lot before braking, and then calms down a bit when he starts to brake.

Further proof of just how awesomely good the FIA test procedures are!!!

The track is banked here. There is som flex yes, but it's exagerated with the banking of the track.
The rear wing angle to a horizontal line is an indication of how banked the track is.

It really isn't – watch the video – you'll see that it's flapping from side to side, and each side banging on the track equally.

Seriously dude, I know you like to disagree with any theory that involves flexing or stories of illegality, but watch the video. Both sides of that wing were oscillating up and down massively - with both sides repeatedly banging against the track.

This isn't anything to do with banking or any other crazy way of trying to explain it away. The front wing was flapping about all over the place to the extent that the commentators thought it was broken!

I think you will find the only thing banked in this picture is the camera taking it.

Why exactly would track banking on a straight section of trac cause one side of the vehicle to be closer to the ground than the other??

Like others are say, watch the video. This is a perfect illustration at how incorrect it is to try and deduce so much from a single picture.

I think this is a political move more than a technical one.

Its perfect. Strip this situation of all niceties and what it breaks down to is a Red bull wing being banned on a ferrari. Next legical step is redbull wing being banned on a red bull. I know it has been said that this wing is legal but i dowbt after a display like today it will continue to be. they will deem it unsafe even if it does pass static load tests.

But why should it take Ferrari building a wing like this for the FIA to crack down on what has been a clear regulation abuse for the last couple of years?

It's just another example of the FIAs incompetence or bias (I prefer to think of it as the former). If they don't want flexible front wings then they should have cracked down on it last season, or at least between seasons.

They give Hamilton a 3 place grid penalty for a technical infraction when they themselves cock up the signalling, but fail for two years to police flexible body parts that they deem illegal when it's waved in their face but turn a blind eye until that point. It shouldn't be up to the teams to work out how others are stretching the rules beyond breaking point and to present their findings to the FIA (or worse have to develop the parts themselves only to have them banned). The FIA should be doing the police work, doubly so given the access to the cars that they have.

[Crabbia]

myurr, totally agree with you and i was going to launch a tirade on the FIA but will i will keep it on topic and... it is the weekend. and you can't hate on the weekend. G*D will kill a bunny.

Well the wing is apparently working better than it looks. Mass 1st in FP2, To those who said it's oscillation would hurt erformance: You don't think a team like Ferrari has done the necessary research on this wing? I guarantee they knew to expect the behavior this wing displayed.

[shelly]

@pierce: what is your source for stating that this behaviour was expected?
I think that the wobbling seen in the video is an undesired side effect.

However, if the aim of the wing is political, such a behaviour certainly succeeds in raising interest

No source but all top teams will move and shift their models around in the to look for nasty side effects. They would also do A LOTsimulation on a wing DESIGNED to bend. When a top team designs a BENDI-WING they are ging to test for negative side effects from the bending. It's just how F1 teams operate. They try to investigate every poosibility. Not to mention the fact that if it was actually hurting them, Massa wouldn't have been p1(regardless of fuel load).

I've just seen the video. That the danger of still picks.

The wing is oscillating. This is called wing flutter. It's not desirable, but i guess in this case , the case of a race car, maybe it helps.

The flutter is probably purposely tuned.

[shelly]

@pierce: the wing probably makes the car go faster, but that does not tell anything about its wobbling being designed, or an undesired side effect.
As I wrote before, aeroelasticity is quite complex; structural damping is especially difficult to estimate (and more so on a carbon structue I think.
I agree with you: they have tested it as much as possible. But those test do not exclude something unexpected like this oscillation happening.
Or maybe it was expected, in order to generate a political reaction.

Interesting thing is that there is not a similar video for korea: so one of three
-the wing/seteup is not the same as in korea
-there is something in this track /turn that triggers this
behaviour
-we have missed something in korea
