With the 2022 rule change on the horizon bargeboards will no longer be a feature of F1 cars, but what are they, how do they work, and will F1’s designers be able to replicate their function in 2022?

Higher edge = less sealing = more air being sucked in and processed by the diffuser = more air being affected by the car = bigger wake / worse following?
Of course this is not all 1:1, but as a general trend
I dunno, in any case the ice skate is gone.vorticism wrote: ↑Sun Mar 26, 2023 4:27 pmThe floor edge was raised for this year as you all know. +15mm iirc. That's about how tall the ice skate was. I read discussion of this rule change being directed at Merc, at Ferrari. Wasn't it more directed at RB to get rid of the ice skate? Considering the dimension involved.

The regs define the maximum area of these apertures (e.g. 150,000mm^2 per side of the car for the sidepod cooling apertures) but the regs don't seem to say what plane this is measured in.
Does anyone know how these are measured? Is it in a specific plane? Or maybe defined when viewed normal to the surface?
This is at the end of Article 3.7.6 but I agree with you that this can be rather ambiguous depending on how the surfaces are created in the CAD model.All areas mentioned in this Article will be measured on the untrimmed Rear Bodywork
surface.
I'm not sure I fully understand. Do you mean planar to the bodywork surface before the apertures are defined? Does that mean they define the sidepod surface, and then define the 2D area on that surface where they want to circumvent the minimum radius rules?AR3-GP wrote: ↑Fri Apr 14, 2023 1:50 pmThis is at the end of Article 3.7.6 but I agree with you that this can be rather ambiguous depending on how the surfaces are created in the CAD model.All areas mentioned in this Article will be measured on the untrimmed Rear Bodywork

Looking at the Ferrari, these apertures tend to be planar:

I thought I replied at some point, but article 3.7.1 to 3.7.5 require you to draw a closed, untrimmed, rear bodywork surface. So basically what you said in your post here is correct:MIKEY_! wrote: ↑Sat Apr 15, 2023 1:54 amI'm not sure I fully understand.

I must be missing something, because some of these louvres areas look a lot bigger than 150,000mm^2 (about 387mm x 387mm), especially last year's sauber.
Only then are these louver cut outs permitted and the surface area attributed to them is simply the measurement from the CAD model. To make the cut outs in CAD, they are probably using 2D extrusions to intersect the side pod. Then this interior intersection area is the area which is regulated.Does that mean they define the sidepod surface, and then define the 2D area on that surface where they want to circumvent the minimum radius rules?
