2017-2020 Aerodynamic Regulations Thread

The underside is covered in red flow vis, so that explains that.

AFAIK the Williams design would be illegal in 2019. The rule will be 5 sections per side.

I believe they have just used an existing flap setup with the new wing - to test the affect on the outboard end without changing the inboard vortex system - that's just a guess though. Could be they didn't want the expense of manufacturing the flaps too.

So these new wings are basically the same shape and form as the old wings. Like, 95% identical in general shape, sans cascade elements. How does this improve things. The two main vortex structures coming off each side of the wing are still gonna be there. Seems like a compromised, minimal approach to solving the 'problem.' Maybe a good consensus was never reached by FIA and the teams and this is the result. If the real reason was cost-cutting/simplification/parity, this would make more sense to me.

Is it? It doesn't explain why the outside of the tyre is clean of red flow viz though. It seems that the wing is either chucking everything up and over the tyre, inboard of the tyre or, more likely a combination of the two. It certainly doesn't look like much is going outside around the tyre.

Reminds me very much of 2009 front wings.

Upper surfaces isn't all that interesting - AND most of those are just after the paint was sprayed on in the pits.

Looks like they are still trying to make out-wash front wings!

Although they do appear to have severely limited options now.

I'm getting annoyed with this in-wash stuff. FIA/FOM never said they'd be looking to in-wash the front wing tip wake - just reduce the aggressive out-wash which increases the car's wake width to the detriment of other teams, then Scarbs and the motorsport network got it wrong and started all this nonsense. That said, a wide span wing does not necessarily mean the tip vortex passes around the outside of the wheels - read the work of Diasinos on front wing span and wheel vortex interactions.

I never said anything about in-wash wings, I merely commented that it looked like teams were still trying to direct air around outside of the tire.

Excellent article.

turbo, is there a way of doing that in relation to the article?

Typically, I have always just created a brand new forum thread talking about the article, and then jjn9128 and I will post throughout that which allows you to do that "in relation to" the article directly.

With this one, given it would fall directly under this thread (and these 2019 changes are a direct follow on from the massive 2017 overhaul) turbo thought that it would be easier to link it to this thread.

Yeah again, apologies mate .
