2021 Qatar Grand Prix - Losail, Nov 19-21

It is called flutter.
Watch this video:


And explanation here:


If you don't decelerate, wing brakes.

But why is it so much more exaggerated on the Red Bull's?

Unbalanced movable surfice. At flying this phenomenon is not wanted. I do not understand why Adrian N. woul'd want this.
Except if it happens becouse of some funky mechanism that allows bigger opening with extreme excentric clamping of the wing.

As I looked a bit more into this what happens at flutter is BIG los of lift on the wing. Therefore drag also gets les and that would be benefitial for top speed of the car.

Yeah that is the possibility.. they are trying to have the flutter to stall the wing... the degree to which it flutters is what they r trying to find out during the practice sessions? Maybe this is why it is failing after or before the qualy

Anyone got the race pace times?

It seems it happen in braking zone. So difficoult to understand what might be the pros and cons

If it only happens in the braking zone then could it improve the braking by creating varying load in a similar way that ABS pulses the brakes?

I doubt it is intentional as I think it has only happened in free practice?

This is the only great track on F1 calendar, currently. Spa is hyped, Mugello turned out to be not that great and Turkey is very good but not enough to be called great.

As such, you should make a special edition of onboards this time around, Juzh

So refresing to see, at last, a track comprised of mostly fast, flowing corners.

In the braking zones the DRS is closed, by definition. It’s fluttering just before that, at V max.
ABS pulses because the pump is trying to not let the wheels lock, the pulses don’t help with the braking. This is especially noticeable with the first gen of ABS, where the computer and hydraulics only could intervene a couple of times per second. These days it’s well above 100 times per second. “Pulsating braking” is a myth by people who didn’t understand how ABS works.

[pipm1]

Yeah, I don't understand anyway!
Of course DRS is closed during braking, whoops! I was just going based on previous comment.

It's not happening during braking

In the video it happens when the DRS is wide open... which means that it's not during braking, coz any touch of brake the DRS closes immediately

It is now four races in a row that Red Bull have had to make repairs to the rear wing..."

It's that the same repairs they had to do in Parc Fermé? Or is that something else on the rear wing?

I hope they don't need to make any repairs in Parc Ferme this weekend, or things could get ugly off track....

[adrianjordan]

Pleased to see McLaren looking racy again this weekend. Maybe we can claw back some of the deficit to Ferrari!!

I think the 'fluttering' is related to what they think Merc are doing and are making it so noticeable there has to be a ruling against it

There is no fluttering in Merc rear wings
There is nothing going on with merc rear wing... if it was redbull would have already protested... I saw honers interview today he said they will protest next week... he said the same thing Brazil that they will protest on next race

The Red Bull drs flap fluttering is nothing new, it did it a few times last year as well!

Anyone get a breakdown of the long runs?

Exactly. He’s gaslighting the public and media.

Make accusations and let the media and the PR machine do its thing, knowing full well it wouldn’t be a valid protest and if it is, they too are open to a counter protest.

It’s sleazy politics at its finest.

It seems to be a moving aerodynamic device and they are using the loop hole that the DRS is permitted to move. FIA need to clamp down by stating the DRS can only move to fully opened then fully closed position for each application. They know how to prevent flutter, but they are choosing to make it flutter as a kind of air ABS maybe?
It can even provided more stability for the chassis. We don't know but it needs to be looked into.
