2017-2020 Aerodynamic Regulations Thread

In a way Vettel is correct (partially), the drivers should be listened to but not blindly. Yes the driver would like faster cars, but I don't think that was their real issue. I think what they really wanted were tyres that didn't have to be babied for an entire stint, even when doing the maximum number stops, so on a 3 stopper a driver should be able to drive flat out on the softest compound, on a 2 stopper there needs to be a bit of saving and with 1 a lot.

Agreed, the 2017 rules could have changed tyres and car width without adding significant downforce. I've defended Pirelli for years, the 2011 blowouts were because teams were running the tyres on the wrong side of the car, overheating the shoulder...etc but lately (since early/mid 2016 for me) it's just got boring. 70% of the race commentary seems to be about the tyres. They tried to manufacture tyres to do multiple stops. It hasn't worked. Let's try a different idea. Something which will allow the drivers to actually push.

I remember that test being mentioned during the 2006 GP2 race in Turkey. It was said the car on slicks went 2 seconds a lap quicker around Mugello or Fiorano.

Good video on 2019 Aero changes.

I hate to moan and gripe but it really isn't. The animations are rubbish, the explanations are weak, the content is inaccurate in places.

Since I'm no expert, I will give way to your wisdom.

I don't mean to be overly negative. It's just that particular channel really irritates me. I mean no offence.

[mclaren111]

No problem. None taken.

Feel free to post the good stuff.

Yeah, I've seen animations different from that and I'm getting confused.
Can you pm or post an accurate analysis? (Either yours or anybody else's)

We don't know what the rules are because they've not been published. All which has been published is those 3 bullet points; wider front wing with less outwash, wider & deeper rear wing and simpler brake ducts. Anything more is speculation

Best I can do is this based on that Tobi Gruner tweet (blue is 2018 red is 2019) hopefully some CFD will follow when more/definitive details are published!!

[PlatinumZealot]

Unless they make the end plates standard the teams will find very creative ways to still achieve the same side wash effect.

[godlameroso]

You can still create outwash with contours on the flaps, the biggest loss of lap time is going to be the increased drag from the rear wing. As Verstappen showed in Barcelona, those little cascade elements don't have a huge effect on downforce.

Not really sure if this is the correct thread, but thought this was super cool, check it out:



At around 1:31 in this Autosport video, it seems to show some basic aero values during some sort of test - nothing too elusive i'm sure, but I can't remember ever seeing Cl/Cd/aero balance values for any modern F1 car before.

This is a screenshot of what I'm talking about:



Unsure of whether this is the 2018 car or more likely last year, but cool to see nevertheless IMO.

Good luck reading that, my eyes can't focus... ~5600N on each front tyre ~8400N on each rear at 296.4km/hr??? That doesn't work out as an aero-bal of 45.921% though...8400N (think I can make out 8453 ?) on the rears with that balance is ~4500N (could be) on the fronts which is 25,800N total. That's roughly a Cz ~3.9 based on a frontal area of 1.6m*m... I've estimated ~3.6 for a 2017 car in the past so that would seem to be reasonable.

[garyjpaterson]

Pretty sure its ~6600N on the front, which would be around 44%f i think.
