2022 Aerodynamic Regulations Thread

I don't know, but did anybody else spot the front Pull rod suspension in the AT-video, posted a few days ago on Twitter?
I know it's just a render, but could this be a new 2022-trend? Since 2014 I only think Ferrari and McLaren had front pull rod suspension.

The showcars obviously didn't have pull but push rod:

It's just the short nose version of the FOM 2022 car

Oh my bad. Sorry.

Who's going to be slick and turn the beam wing into a ducktail with outwash outer edges?

[theVortexCreatorY250]

By stopping the y250 from migrating inboard, but it also interfered with y250 formation if it was too far forward. The stagnation pressure at the cape inlet also steered the y250 as a high pressure trough steers hurricanes. But I'm drawing a blank as to what was meant by downwash from the y250. Help me out here. How would no y250 stop a cape from helping to channel front wing airflow to the floor a bit more effectively? Other than it being illegal per regulations ofc.

The downwashing side of the Y250 hits the cape edge at almost 90 degrees - most importantly the cape vortex can only exist if the Y250 provides the downwash. The goal here is to NOT make the cape provide clean air but rather lots of mixing. Notice that the cape is counter rotating to the Y250 BUT co-rotating to the barge board floor slots and the floor leading edge vortex generators. The whole aim of these cars is to spin the air one way under the floor to get more mixing. The cape is the first, then O-nose fences (where applicable) then barge board slots, then floor leading edge vortex generators and finally diffuser strakes.

So the y250 downwash raises the pressure on the top surface of the cape, creating the pressure differential between the upper and lower surface to make the CC cape vortex?

The nose on the new cars and the front wing connecting to it can create a CC vortex, the nose cone acting like an endplate for the inboard wing elements.

The direction would be the opposite way to the current cape as the air is upwashed onto the underside of the nose which wouldn't be beneficial for the floor. But the regs stipulate minimum radius' all around the nose to prevent sich an action. I'd image teams would be using the maxium sized fillets possible.

FIA is using those aggressive sidepod inlets in their renders, so I assume, that teams can use that space in their constructions. Would it be possible to recreate something like F2008 side wings there, or must it be a continuous surface, when viewed from above?

blue - side wing
yellow - more conservatively shaped sidepod
green - side impact structure

Apologies if this has already been asked (and it may well have on the 108 pages of this thread....) but does the way these new cars supposedly- as far as I understand, which admittedly is limited- deal with getting dirty air/wake/turbulence out of the way mean that slipstream will be (much?) more powerful this season than before?

No. The sidepod inlet box has to just be for sidepod inlet. However the box around the cockpit entry doesn’t have a minimum radius. So I expect some winglets or deltawings and some complex bits around the mirror join.

No. Slipstream is the same process as dirty air so slipstream will be less next year. That’s why drs is staying.

Ah, got it- thanks! Hopefully less silly arse qualifying sessions then.

Never.

Aside from producing a cleaner wake behind them, cars should, in theory, be able to follow more closely and race harder as most of the downforce is being produced by the much more efficient under-body wing (Venturi tunnels) which isn't as sensitive to dirty air as regular wings.

I'm super hopeful that this will be the case as the basic Aero formula is going to be very similar to the Champ Cars of the '90s and early 2k's which had some of the best open-wheel racing ever IMO.

Wasn't sure where to post this, but do we know how much more the new wheels are going to weigh vs the old ones?

Edit: I don't want to delete even though it's the wrong thread, just want to point people here - viewtopic.php?f=6&t=27487&hilit=2022&start=435

Check out the 2022 tyre thread, Blackout posted some info just the other day...

Is that total corner weight or tyre weight? I imagine the former.

Why Formula 1 Is Going to 18-Inch Tires, and What to Expect
Move to 18-inch tires is part of the wide-ranging technical changes being introduced for 2022.

Drivers also had to get used to the slightly different view, with the new tires larger and thus making seeing the curbs harder, while overall there is an 11 kg weight gain from the four tires: 2.5 kg front, 3 kg rear. A few drivers tried out the new wheel covers, which may feature LEDs for potential sponsorship purposes, but knowing the effect of these so far is tricky due to the different aerodynamics and braking systems for 2022.

Isola says car mass increased by 14 kilograms due to heavier wheel/rim assemblies, split roughly 3kgs per front wheel and 4kg for rears.

That is only the tyre weight, rims must be a lot more
