Notice they can't change the angle of that element? If say it generates in the order of 200kg lift above 180mph, then this has to be countered by using more extreme front and rear wing form (they are doing this ) with the attendant drag that brings.
There's no way it makes that much lift. You need a relatively large single element rear wing to make even 200kgf of lift (downforce) at just over 200 km/hr.
So it does generate lift then
That was a projected guess and at 300 km to clarify. I don't think that's far out in reality for the surface area it covers.
Everyone keeps extolling the virtues of it as "downwash" (I know the reasons to attempt that effect) and justify it as part of their design solution. The raw reality is they keep, MB, demonstrating week after week they are lost in what's going on with their concept, que mystified explanation from LH, ME, TW etc etc. If they really knew, then they'd fix it.
Their language doesn't tally with the knowledge they proclaim.
Statement of problem;- lacking downforce, heading rapidly towards two years now (inclusive of W13 gestation) and still no progress.
The floor isn't that hard to make, it achieved too much negative load in ultimately making it porpoise, the problem is something else.
Complete projection/theory IF that mid wing is producing significant lift (just look at the attack angle and say otherwise) then that's fixed for the whole year.
Corellation in W13 performance, notice how that performance improved at circuit specific air density shifting Texas-hot, Mexico-altitude, Brazil-altitude, all in which the mid wing can execute less lift to the vehicle. Each example can probably show increased front and rear wing load giving dominance over that diminished mid wing lift. Performance relative to other tracks improved.
Compare to Imola, damp conditions, LH with "trial" setup, did anyone see that car coming across the line chasing Gasly, it has very substantial front lift on chassis, and awful performance to go with it.
They look at macro correlation, when in reality a holistic view of season with W13 may tell them more.
They are trying to run an aggressive floor to counteract that mid chassis lift, unsuccessfully. The side pods need to change before they get anywhere.
This corellation is stated by LH in complaining about never being able to get a good balance, they are sitting on a knife edge, that edge is defined by proximity of wing downforce and how close it comes to cancelling mid wing lift.
Notice also, that front wing bending back under load (all teams have this) as the download of that reduces the mid wing just carries on up as speed climbs, the two effectively crossing over in the direction of their lift, that's inconsistency for you. No wonder the drivers struggle to describe it.
That's my belief, they've got to start looking at things pragmaticly, rather than references to Diva, shitbox etc. That won't solve anything.
