Ferrari F2012

No worries.

I think preventing something like this is probably what they had in mind.

[Nickel]

Yep, understand how it bans that. But with a partial slot, as long as the rules regarding radii are respected, and nothing is visible from the side... both sides of the slot still have a >100mm radius no?

[bhall]

I think, "When viewed from the side of the car no longitudinal vertical cross section may have more than one section in this area," would probably be better worded informally as something like, "The profile of any longitudinal vertical cross section may have no more than one section."

If taken literally, the official language of the regulation would open up a host of possibilities, because when viewed from the side of the car all you see is the endplate.

I hope this makes sense. I often find it terribly difficult to visualize the images conveyed by the regulations, so I'm probably not very good at explaining them, either.

You're right it is very confusing, maybe they should have said something like: "When viewed from the side with the endplate removed...."

[Twaddle]

We're starting to get off-topic here, but the wording clearly talks about cross sections, not the visual profile of the car.

I hate reflections sometimes. I really couldn't get my head to see that not-a-slot in the rear wing as anything other than a slot, although it would clearly be illegal.

[bhall]

Actually, the "slot" was way off topic. (It almost always is.)

I think its probably instinctively impossible to distrust what your eyes are telling you, because, in many ways, survival is predicated on our senses. So, I really do understand why people won't back down from proclaiming the truth in what they see, even if it flies in the face of everything they otherwise "just know" to be true.

After all, seeing is believing.

09:50 Now Massa is on hard tyres, and goes quicker yet again with a 1m22.896s.

[Crabbia]

Have just seen some new pics of the RB8 with their revised exhausts, and I feel that Ferrari have missed the boat here with their original launch exhausts.

They're clearly going to have to work very hard before Melbourne to catch up...

it could be seen as reb bull having missed a trick not having outboard exhausts and they are playing catch up. they now have to evaluate a completely different solution which mclaren and Ferrari have had 8 testing sessions to evaluate and tweak.

it depends where you allegiance lies. i want to see pics from today to see if they went to the original placement of the exhausts or stuck with the more inboard ones.

simple answer is we won't know till the first race at the earliest and possibly not till mid season when we can see how the development potential of the respective concepts is playing out

The RB8 does have outboard exhausts. It's only because they're more well thought out that they look so dramatically different than Ferrari's solution.

Older floor





Exhaust seems to be a little different than yesterday.

[bhall]

That's just wishful thinking after seeing the Red Bull exhaust. Don't worry. It happened to me, too.

(For what it's worth, I don't think the Red Bull design would be terribly difficult to copy.)

Nope because they are talking about cross section. It is not "Let's stand to the side of this car and check what our eyes can see" but "Let's get a side IRM of this car".


Anyway

When viewed from the side of the car no longitudinal vertical cross section
may have more than one section in this area. Furthermore, no part of this section in contact
with the external air stream may have a local concave radius of curvature smaller than 100mm.

It is 3.10.1 and refers to the beam wing.

Complete article is:

Any bodywork more than 150mm behind the rear wheel centre line which is between 150mm and 730mm above the reference plane, and between 75mm and 355mm from the car centre line, must lie in an area when viewed from the side of the car that is situated between 150mm and 350mm behind the rear wheel centre line and between 300mm and 400mm above the reference plane. When viewed from the side of the car no longitudinal vertical cross section may have more than one section in this area. Furthermore, no part of this section in contact with the external air stream may have a local concave radius of curvature smaller than 100mm.
Once this section is defined, ‘gurney’ type trim tabs may be fitted to the trailing edge. When measured in any longitudinal cross section no dimension of any such trim tab may exceed 20mm.

Rear wing flaps are regulated by 3.10.2

Other than the bodywork defined in Article 3.10.9, any bodywork behind a point lying 50mm forward of the rear wheel centre line which is more than 730mm above the reference plane,and less than 355mm from the car centre line, must lie in an area when viewed from the side of the car that is situated between the rear wheel centre line and a point 350mm behind it.
With the exception of minimal parts solely associated with adjustment of the section in accordance with Article 3.18 :
‐ When viewed from the side of the car, no longitudinal vertical cross section may have more than two sections in this area, each of which must be closed.
‐ No part of these longitudinal cross sections in contact with the external air stream may have a local concave radius of curvature smaller than 100mm.
Once the rearmost and uppermost section is defined, ‘gurney’ type trim tabs may be fitted to the trailing edge. When measured in any longitudinal vertical cross section no dimension of any such trim tab may exceed 20mm.
The chord of the rearmost and uppermost closed section must always be smaller than the chord of the lowermost section at the same lateral station.
Furthermore, the distance between adjacent sections at any longitudinal vertical plane must lie between 10mm and 15mm at their closest position, except, in accordance with Article 3.18, when this distance must lie between 10mm and 50mm.

The most important is that the sections must be "closed". Otherwise you can have a slot and it doesn't broke the 100mm radius: you cannot calculate any radius between unlinked point. If you are still not convinced, the 100mm radius rule was already here in 2010.
So passive F-Duct is authorized on beam wing but impossible on rear wing flaps.

I know. I said that. You even quoted it. It's right there.

EDIT: You're also improperly defining "closed."

Code: Select all

1.21 Open and closed sections :

A section will be considered closed if it is fully complete within the dimensioned boundary to which it is referenced, if it is not it will be considered open.
