Some new sculpting of surface at the outlet just ahead of rear suspension. Maybe intending to introduce some upwash to prevent losses spilling downwards as much

If I get it right, first element is acting like slat with downwash working with the second element to generate more negative lift, opposite to aircraft where is up wash for more lift?Vanja #66 wrote: ↑Fri Jul 19, 2024 12:27 pmFirst element often features negative angle (or positive angle in aerospace nomenclature).

Seems like in this configuration it is functioning as a slat. I think it was a mistake to extend the RB20 nose tip to the leading first wing element. The other cars have gone for what the RB18 and RB19 had been utilizing and I think that allows for better balance and more ride compliance.FDD wrote: ↑Mon Jul 22, 2024 2:21 pmIf I get it right, first element is acting like slat with downwash working with the second element to generate more negative lift, opposite to aircraft where is up wash for more lift?Vanja #66 wrote: ↑Fri Jul 19, 2024 12:27 pmFirst element often features negative angle (or positive angle in aerospace nomenclature).

It just increases the camber of the front wing system.FDD wrote: ↑Mon Jul 22, 2024 2:21 pmIf I get it right, first element is acting like slat with downwash working with the second element to generate more negative lift, opposite to aircraft where is up wash for more lift?Vanja #66 wrote: ↑Fri Jul 19, 2024 12:27 pmFirst element often features negative angle (or positive angle in aerospace nomenclature).

It's a bit more complex. First element also generates downforce as a part of the front wing, so there is no downwash involved. Slats (and the first element here) form a slot above the second element (and the main part of the wing on an aircraft) which is used to energise the air by accelerating it. This increases suction on both elements since it bleeds high pressure on top side, converges the air through a channel and blasts it out moving 3-4 times faster.
Looks more like introducing local curvature on both top and bottom side (as much as possible) to form a diffusing surface to aid with hot air extraction.

I have 2 major concerns about this article. The timeline is incorrect, the rule has changed in July, yet the part was not used (while still very much legal) after the Chinese GP? There is months in between those moments.FW17 wrote: ↑Thu Aug 15, 2024 12:56 pmhttps://racingnews365.com/how-a-minor-f ... n-red-bull
From RacingNews365's sources, it appears that the RB20, up until the Chinese GP, mounted an inertial valve on the braking system section at the rear downstream of the brake-by-wire system.
In practice, a valve with a T connection received a single hydraulic pressure directed to the rear axle by the brake-by-wire, but which could be precisely directed with greater pressure to the left or right of the rear axle, depending on which way the car was turning through a corner.
These are traits the RB20 has progressively lost from Miami onwards, something not even subsequent upgrades have managed to remedy.
