Interesting article talking to Pat fry about floor rigity and FIA’s pre-season concession in allowing floor stays to help alleviate porpoising problems.

Hope this is the right place for it.

Alpine has no floor stays. The got screwed over. Now they have to redesign the floor for the weight savings and run the stays so they can use ballast elsewhere for better cg and polar moment.

Merc and Ferrari used their political weight to get the FIA to even consider the stays.

LOL, You make him sound so bitter.... He just said "It's all part of the game, and we'll have to consider this concession for the next update."

Think originally you were only allowed non visible(internal) stays ?

These interior stays contribute some stiffness, but you could make an even lighter floor, if you can mount the stay to the outboard tip of the floor in front of the tire as Merc and Ferrari have done. It's the classic cantilevered beam and distributed load problem from uni.




The deflection at the outboard tip is related to how close you can place a strut to the outboard tip. Any reduction in deflection that you can gain from the strut placement, will allow you to make the floor thinner. It's much more efficient in terms of weight to add strength with a strut, than to make the floor thicker.

I wonder where it stops... maybe at the front wing top 2 flaps.. or the 3rd one

The answer: Its tip is located a little behind the front wing's 2nd flap leading edge.
So the yellow part is hollow.

Alpine lighter than 4 kg: a new fund has arrived

Wonder what's in that little hole that they need to leave a trap door to get to ?

Usually it's pressure sensors embedded in the underside of the wing.

If you superimpose them

BTW, I'm having 2nd thought about there being a new wing. Starting to think it's just the change in the way it looks as the angle of attack increases.


I also looked at several pictures of the so called new floor, it doesn't look any different to me.

all the cars seemed to have been covered in a chaulk or baby powder. That left a residue. Any idea what that is ?

The document only mentions new floor fences - not a new floor.
"Bigger floor outer fence and realigned forward floor fences compared to its previous design"
Fabrega has a comparison

[chlebekf1]

but the new floor is the same as in Arabia, only 4 kg lighter
