2022 Aerodynamic Regulations Thread

[mzso]

There's a misunderstanding that the floor will be producing more downforce - it'll be around the same as now.

I have trouble believing this.

(By the way, shouldn't the thread title change to "2022 Aero Thread"? )

Thanks Jjn.

Sh**, they should have taken inspiration from the Jordan 191 for the FW


But maybe the car would look too much like an indycar? https://racerdigital.files.wordpress.co ... 1000&h=563

One of if not the best looking F1 cars of all time.

Will some sort of endplate allowed in front of the rear wheels and direct the flow inboard.

It will be interesting to see how the teams approach ride height. Trying to run the floor as low as possible would seem to be sensible, or will a bit of rake still be beneficial?

I think some rake will still be beneficial, it's difficult to show in the 3-d pictures but the centre (inlet region/centre/diffuser) of the floor has a slight nose up inclination, so rake will the centre of the floor be an expanding volume. The rear wheel hub vanes then protect the diffuser from tyre squirt somewhat.

The more I look to these tunnels, the more I find them complex and very different from the wing cars and the champ and Indy car tunnels.

The car in all the images released so far is the "India" concept though. Talk is they're up to "Kilo plus" (the 11th iteration ) now - but no images from that so far - which could well be closer to the motorsport picture.

So they discarded that tunnel shape https://www.racefans.net/wp-content/upl ... -floor.jpg
and the final shape is this?

I'm sorry I'm not seeing much difference This is the pressure maps of our car and theirs compared. That was the "India" model, note the front and rear wing endplates changed a bit, I guess there could have been some small variations in the floor rules.

It seems to me the India tunnel roof near the center has the shape on the top (side view) while the other has the bottom shape https://i.imgur.com/dA5CdBq.jpg

You are right the inlet part of the India floor is flatter than ours, not quite how you've drawn it but similar, the pressure isn't significantly different though. I think the rules, as currently drafted, make that sort of start to the floor hard because there's quite a thin region to play with. I think you'd be sacrificing some height at the leading edge to make the shape. I could be wrong about that though.

We've been a bit lazy, I'd love to do some more CFD at some point, but I have to sort some CAD first.

Looks like F1 is going to be merging with Indy sometime around 2025. Basically a spec series with little for the teams to do other than turn up and polish the paintwork.

That controls cost, what's wrong with that? Between 2007 & 2012 there was little for "power unit" manufacturers to do on their frozen V8s (sure, there were EBD off-throttle maps) and they didn't complain, instead reaping the profits of exposure with less R&D expense.

It's not F1. F1 isn't a spec series. Quite simple really.

You're at least 20 years too late there. Lotus had their drivers lying down in the 1960s.

Precisely! Everything old is new again, for example the teardrop shape of the rear ends of veteran Grand Prix cars is still replicated by the tear drop shape of the bodywork around the gearbox of modern grand prix cars.

I'm not sure why the driving position became more upright in the 70's and early 80's -- most logical reason would presumably be the progress towards increasingly enormous rear tyres and an extremely rearward weight distribution, compared to the late-1950's and 1960's cigar type F1 cars with much narrower rear tyres.

Whatever the purpose there were good reasons for it, nobody designed their car to be slow on purpose! It seems generally in the late 70's and early 80's, the driver was positioned more forward in the car which necessitated a more upright position... Perhaps also some rules around safety, & protecting the spine?

I am not sure if it was regulation that forced the change from dual fuel tanks alongside the driver to a central fuel tank behind the driver, but that would have played a part in the driving position too.

I assume the 2022 cars will be a lot slower than the current ones given how much less floor space they have to play with and the lack of endplates on the rear wing?

Will they really be that much shorter???
