Scuderia Ferrari SF70H

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

But I was rather focusing on what i've highlighted in green above the picture below... they do not seem symmetrical, meaning at the same height compared with tyre/upper suspension arm... are they moving up and down somehow when braking or it's just a mounting issue?

My bet is they're moving as the steering is turned. It's well established in the rules that brake ducts don't have "aerodynamic influence" (cough, seriously, cough). So it's valid for them to move.

I noticed that, too. It kindasortamaybe suggests that I've not been completely out of my mind in thinking that Ferrari's huge brake ducts over the last few years have been much less about brake cooling, or even the vaunted blown axle, than they are about managing air flow from the front wing when cornering.

For the outside part of the wing--relative to the turn--the duct is in a position to collect air flow from the flap. That can conceivably increase the wing's efficiency as well as prevent such air flow from getting scattered between the wheels and subsequently sucked underneath the floor.

For the inside part of the wing--again, relative to the turn--the duct is positioned to collect the wing's edge vortex. If so, it will have much the same effect as above.

I think the "real" front wing might make things clearer. (I can't imagine that what's on the car now will ever race.)

Is Ferrari the only team with double pilon rear wing? They also did a quite complex design around tailpipe and wastegate pipes. What could be the reason? Better exhaust gas flow control with monkey seat?

That drop in height of the brake duct is a function of the camber angle and the caster angle plus the distance of the duct away from the axis. The axis of rotation has an inclination to it so this will happen.

So car changes camber when it turns?

That must be a first in F1

Those brake ducts are more like blown hub ducts. I doubt even 50% of the duct is for brake cooling.
For Sure!!

No.. Absolutel not.

I am not sure you understand kinematics though?

You would have to do the geometry and maths yourself to see why the suspension moves the way it does. No easy to explain. Here is another car at similar lock. The arc of movement of the brake duct is on the down swing when the wheel turns inboard based on camber, caster ackerman, scrub radius all these geomtrical things.. It is just geometry.

How Ferrari finally went their own way with new SF70H? https://maxf1.net/en/how-ferrari-finall ... new-sf70h/

Compare body work Ferrari to Toro Rosso, I mean carbon fiber work. Edges on Ferrari are thicker, it looks like old school. TR body work looks more slim and air flow friendly. I could be wrong but... :?:

Does a teardrop looks old school to you? Thicker edges are not necessary draggier. If anything, a blade produces a vortex while rounded shape enables a laminar floor.

So, whether a twin keel or not, it does seem as if Ferrari have worked to lower the bottom wishbone; meanwhile, Mercedes and TR have raised the upper wishbone. Is this, in some way, a different way to try and do the same thing - I.e open up set up possibilities for a new type of tyre?

Interestingly, in 2007 - when having to deal with the (to them) new demands of a Bridgestone tyres - Red Bull resurrected the twin keel:

At the time, as scarbs' article explains, that was about making the front weight biased tyres work; you'd think that these new tyres are very rear weight biased, but I can't help thinking that there's something in the idea of going to this kind of suspension set up (if indeed they have) and a very new type of tyre.

It's an optical illusion.

There is some body roll, so the suspension arms are not at he same angles from side to side.

Also the wheels are turned. The outside wheel's duct moves closer (front to rear) to the suspension arms while the inside wheel's duct moves further away.

At the angle of the picture this makes it look as if the duct has moved. The reality is the duct is fixed to the wheel hub, so you should look at the relationship between the duct and the tyre to see if it has moved.
