2022 Aerodynamic Regulations Thread

[PhillipM]

Inerters won't fix the issue because the issue is the teams allowing the floor edge to ride along the ground. That's what the FIA are trying to stop, before it leads to a big accident down the road as the cars develop.

Will it affect the *poorer* teams who could have carried parts etc over the next season ?

Secondly, how do the teams know that raising the floor will help? Has there been research carried out and data shared by fia/fom?

Thinking out aloud her: Why is a 10mm change acceptable and not 25mm? Whatever the increase, new aero tests will have to be conducted unless they have accurate 0D models that can predict such changes ?

Well, poorer teams now have the same development budget. So it's a matter of choice what you'd want carry over. However I think the cost is overblown (by Horner mainly), since the floor/sidepods seem to be the main distinguishing parts of a car, that is what they would want to redesign first. Also Haas had no trouble completely changing the whole sidepod design within half a season.

The 25mm the FIA probably just pulled out of the air. The same place 10mm comes from, by the teams who'd think it's less disadvantageous for them. I think it should 19.23mm, just to look like it was a results of some complex calculations.

(No idea what 0D means)

0D = zero -dimensional or 1D models - essentially lower order models built from larger dimensional models (3D CFD/WT test/track aero)

The only “penalties” I’m in favour of, are forcing a team with excessive bouncing to address it - or risk being disqualified.

That's sure to be a sh*tshow, as I detailed above. Making bouncing impossible is the real solution.

Zero dimensional models?!

1 dimensional models is understood. It's a series of equations linking to another. One set of parameters gives one result at at pne state or one point.

2D is a planar/cross sectional simulations where you generate a 2D map of results.

And 3D generates results in 3D space.


So when you say zero dimensional... That must be a single constant or something..

Drivers cause bigger accidents by driving like blind bats into T1.

Completely irrelevant to the issue. Sudden loss of massive floor downforce caused by the floors rubbing the floor and unseating over a bump or a kerb is likely to send a car airborne into the catch fencing at some point.

Made some very interesting comments about Mercedes porpoising. Around the 1.05 hr mark he said that at Sauber, they use a rougher belt on their wind tunnel. Then he showed a picture of Mercedes wind tunnel where they had a very shiny, and likely smooth belt on their wind tunnel and speculated that that could have been a problem for them in understanding porpoising

That means all they learned in 2022 is useless

Do you think they are aware of that?

[jjn9128]

... seriously? You think belt roughness isn't something which occurred to Mercedes?

[Venturiation]

I don’t think so, maybe they were more focused on the car than the tools

But shovlin did say in a recent interview that they modified their tools to have better correlation so it could be that

[PhillipM]

Belt changes are a normal part of testing correlation, they would have tried that.

A nice article with quotes from technical figures in the sport highlihgting technical aspects of the 2022 regulations and teams' different approaches to various areas of the car

[AR3-GP]

Interesting.

Simone Resta comments near the end that they studied both concepts and felt the no-pod did not have as much potential.
