2017-2020 Aerodynamic Regulations Thread

2019 regulations have been published on the FIA website today for anyone interested - fia.com/regulations

Good grief the front wing rules are now very convoluted...

Yeah we will be doing an article on this with quite a few drawings.

So it seems that rear wings will also get "lenghtier" (from side view) apart from taller, wider and deeper! The 2019 regulations state 810mm length instead of the 2018 710mm length! Am I right?

Yes, because of the slant the taller rear wing box moves the rearmost point backwards - the bottom is now 550mm behind the RWCL not 450mm. Not sure why this is... likely for sponsors but could be to make a nice round value on the dimension, it will (along with the longer front wing overhang) make the cars look even longer than now though.

Just going through these massive changes, me and jjn9128 noticed the drawings included in the pdf are not always correct. The bargeboards on the drawings for instance sit in an exclusion zone, and the front wing endplate does not extend to the full 1000mm unlike what the drawing tries to sell. So do keep that in mind.

Surprised no one has bothered to mention that not only the rear wing will be wider, but it also widens the retraction by 5cm on each side giving this part of the rear wing more aero potential.

Am I mistaken, or do the drawings also not show that 'more than 400 mm from the car centre plane' divider in rules for the front wing profile? Nor are the 500, 800 mm boundaries for those two strakes shown, it seems.

Teams also get a technical appendix with more drawings, that's not available to the public though.

Do you have an ETA on that? Not pushing, but I keep looking for it and if its going to be awhile I can stop doing that so frequently!

We are looking into it. jjn9128 already prepared something, so I think this week probably and if not next week. We might 2 articles, one to explain the regulations and one where we bring a feasible example. Currently we are discussing a possible loophole.

I admire your dedication but you really don't need to get through a medical operation just for us on this website!

While I am sacrificing useless organs for the cause, you guys can enjoy part 1:

We are going to do a second part where we will try to bring a realistic front wing to the table and discuss solutions.

UV for the first article. Thanks, look forward to the 2nd.

Thanks turbof1 and other contributing team!

Despite the restrictiveness of the rules, I'm curious to see how the front wing will work next year.

The article was in full written by jjn9128, so he deserves full credit.
