The issue is between low speed understeer and high speed snap oversteer and losing and having to catch the rear and then never having full confidence to send it. The wind tunnel never recreates the conditions that causes a vehicle to experience snap oversteer but from simulation and driver feedback pointing toward balance that a front wing that loses down force in certain conditions may help to calm the rear. The lesson is walk back from pursuing peak down force if you can't balance it or use flexiwings to change the behavior or AoA for different corner types.

McLaren changing all their rear wings to stop flexing, and all of a sudden stop dominating. Surprise, surprise? :wink:

The squad has denied this but has conceded that as part of ongoing dialogue, it has agreed to make changes to its entire range of wings, including the one that will be used in Austin.

It is understood that this involves modifications to the upper element to stop it from flexing, as well as a narrowing of the slot gap.

Other teams also had to make modifications.

https://www.autosport.com/f1/news/mclar ... /10664990/

"We issued after Singapore some communication about rear wings, saying what we would consider acceptable or not acceptable," explained Tombazis. "Two or three teams had to make some small tweaks to adjust to that."

It is not confirmed which other teams had to make changes as a response to the FIA guidance, but sources suggest that all of 2024's race-winning outfits have been under the spotlight for potentially pushing the limit of the rules with regard to rear wing flexing.

So they were illegal. Nothing ‘goodwill’ about McLaren changing them.

It's cheeky to act as if you're the team that's above it all but would now breaching the regulations.
While McLaren's 'mini-DRS' wing fully complied with the regulations and was legal at all times, Tombazis did reveal that the FIA's ultimate conclusion was that it was not happy with the design.

Asked whether the team would have been reported for a rules breach if it had continued to use mini-DRS, Tombazis said: "Yes, we would have, because we specifically gave a warning to them.

"We said, 'Look, we consider that as something you need to change.' If they had ignored us, and they generally don't, then we would have reported them."
It's about time that all calm down a bit and focus on the action on track instead of all these mindgames.

That'll be why Zak's deflecting the issue from his own back yard and spouting complete nonsense about other teams. He was even going on about getting RBR staff to sign a affidavit to say they never used the bib device. Get a grip of yourself Zak.

Mate, could I bother you for some onboards of front wings of Ferrari and Merc in Austin race? In clean air, if possible at all :mrgreen:

Cheers!
And they call it a stall. A STALL!

Efin legend! :mrgreen: Awesome stuff, thanks a lot! Ferrari wing seems to be more flexible at slightly lower speeds than it was in Singapore, but overall total flex looks about the same (and not that far from McLaren). Mercedes "new" wing is still a flappyti-flap noodle wing and as long as they keep it they won't fix their issues

RB20 is optimally balanced in high speed corners by design, I'm not sure if they can get a big benefit in slow-speed with such a stiff front end in any case. Their latest front wing has its adjuster back outboard for a while and there is some amount of flexing included already.
And they call it a stall. A STALL!

Could you do the same for Red Bull? I would if I had access to those cameras.

I think you can not copy the main effect of the movement we see at all:
They generate a vortex by the step in the wing at low speed. What they seal off with it would be interesting. They simply designed the wing to flex to an even shape, removing the (strong) vortex once at high speed to remove the according drag. The main movement we see is basically a "switch".
One of the most puzzling things to me that this is counted legal. I mean...they even have metal guiding plates to guide the movement of a part, that is not allowed to move. But in the end I think this is quite simple, but can not be copied without the complete picture of what they do with thit vortex.

In terms of flexing the more interesting part is that they all move to paper thin upper wing plates. You can barely see it on the video, but my interpretation is, that they flatten at high speed, loosing the curvature. I think on the Ferrari one can see this better, it really gets a different curvature at top speed.
They also do not paint this part at all. Just McLaren uses a sticker in some part and keeps on replacing this sticker from track to track.

Ferrari wing raises something fierce now.

As for Mclaren having to modify rear wings, Mclaren had lots of downforce last year, but were draggy...
This season after Miami they became good in both areas...

Both sides of flexible flaps are on the same pressure side - the fixed end near the nose and the adjustable end that flexes. Top side is pressure, lower side is suction. There is no discrete chord length change that can innitiate a vortex. Mercedes made a very loose interpretation of flap size, continuity and other geometric rules to form a discrete sharp edge on 4th flap that can shed a vortex.

Plates fixing the flaps on either side are there to act as endplates, ie to prevent spilling and prevent or at least move vortex shedding. I think they are there for legality reasons too, very handy to prevent vorticity. The whole intent of 2022 rules was to prevent any geometric shape to form surfaces that can shed an inboard vortex.

If there is enough of a pressure difference between either side of fixed and moving flaps to shed a vortex, it will be very small and weak as you need a significant Cp difference to get one rolling.
And they call it a stall. A STALL!
