Ted Kravitz has just said that Ferrari rear brake cooling ducts are under scrutiny from Charlie. Any one know why?

[BlackSwan]

what are those slot gaps for? (under the brembo logo on the white strip beneath the exhausts)

Vents!

for what?

Cooling! were introduced in the last gp.

The checkerboard-pattern is called "spread tow" and I think it is patented by a Swedish company. IIrc redbull were the first to use it. As far as I remember it is thin and has a good drapability, so it is often used in bodywork big panels , with strips of other weaves making a frame all around and acting as a reinforcement

Yes indeed that looks like Spread- Tow. Actually the drapability (around 3-D shapes) of Spread- Tow is not quite as good especially compared to twill weave but for a given weight you can achieve somewhat higher rigidity. It is partiuclarly usefull for flat plates or two dimensional shapes where no clear Load Path exists (in those cases Unidirectional weave is ususally a good option).

Man, these cars basically have four rear wings these days.

The main rear wing forms a wing (duh).

The beam wing forms a wing (duh).

The rearmost, upper arms of the rear suspension basically form flow conditions for the beam wing air flow.

Then you have the covers that go over the drive shafts and rear lower suspension affecting airflow between the beam wing and floor.

That's basically four wing shaped devices.

No the suspension arms and driveshaft covers may not be shaped like aerofoils. They must be symmetrical.

Some airfoils are symmetrical. There are dimension restraints on some or all of these elements. You can get lift (up or down) from a symmetrical airfoil

With negative AoA, symmetrical airfoil will produce downforce.

[tony77g]

no difference for me.

[f300v10]

Does anybody know if these sidepods are the same new ones used in the last race (with the bigger bulges) or the older ones? They look thinner to me.

Agreed, they appear to have gone back to the China spec sidepods for this race, not counting the development parts tested in FP1 by Massa.

FIA is apparently looking into the front of the floor of Alonsos car, flex or wear?

Yesterday they were looking closely at the rear brake cooling ducts, but I heard nothing more about them.

From the BBC: Alonso scrutineering thing. Was never any concern. Was standard random check on bib, which is always done in the team's garage w FIA kit

Yes, they call it aironeutral. Same as the cameras on the car.

¿how many upgrades in Ferrari for spain?
