Williams FW43B

[Moctecus]

Williams's steering wheels featured integrated screens from 2000 to 2013. They introduced a new steering wheel with 2014's FW36 to move the display to the dash (while retaining the old LED-screen). They switched to the larger LCD for 2015. So their current layout is not a leftover from ancient times that they are sticking with to save money. It's a design choice.

Different rear wings from the test

I wonder what those 3 dimples on top of the rear crash structure are for, FW43 didn't have them.

Diffuser comparison vs 2020

Looks like a similar solution to McLaren?
Unless the pic quality is hiding the detail...

Changes to the upper wishbone and the rear brake elements compared to 2020



Cooling outlets tried last week

[PlatinumZealot]

Upper wishbones are clean. Almost as RedBull.

Probably mounting points for an aero rack

Having a look at the CAD files from the "leaked" launch (read they were dumbasses). Unfortunately I think it's too dirty to do any CFD with - also the cooling and engine intake ducts sort of go nowhere. The wheelbase is ~3.6m give or take a few mm, which is the max for 2022.

Interesting diffuser design - as far as I can work out they cheat the length by having a sharp disconnect up in the air at the start line of the diffuser (measurements in cm with the orange box representing the diffuser volume) with a trapped vortex. I do wonder if this is a real diffuser or just something to throw other teams off.

Such design was already done around 2000, afaik the Jordans had a very similar kick

Yes. I'm surprised they've "lengthened" the diffuser so much though.

I guess it's this rule:

The surfaces lying on the step plane which do not meet one of the vertical transitions may be curved upwards at their boundaries with an arc whose radius of curvature is no greater than 100mm at any point, with no inflection, which is tangential to the surface and applied perpendicular to the boundary. In no case may the arc start further than 100mm from the boundary (when measured on the surface and perpendicular to this boundary).

How do they get the three fins / VGs in below the diffuser? Doesn't the surface facing downwards have to be visible from below? I.e. the diffuser's surface must be visible and those fins would prevent that.

Those are the footplate - it's a weird quirk in the software because the mesh isn't watertight it shows parts which aren't on the slice plane as if they're on the same plane.
