Yea its the new nose according to those pictures thanks.

[Sevach]

i would say the nose shape itself is the same, the FW supports might be different.

And of course the FW is the one tested during the YDT.

Anyone else think the pillars looks more like this / \ if viewed from above.

Sorry i think that was a optical illusion (in some sort it is, because the curvature is still the smaller like it seems)...




So they had new/old wing to make corelation/comparison between this two solution... Also maybe the same with the nose etc.



EDIT: Correction of wrong words about illusion percepcion...

Nope its is optical illusion... THAT curvature is in direction if longitudinal axis of the car... And also they couldn't do that, because of rules...

And how do you explain Ferrari's FW pillars?

Yes i was wrong (look i edit previous post) and im sorry for confusion... Now i carefully look the rules boook and discover that small curvature it is still allovable in 25mm thick window and 10 mm radious...

Code: Select all

FIA 2012 regulations book
3.7.2

Any horizontal section taken through bodywork located forward of a point lying 450mm
forward of the front wheel centre line, less than 250mm from the car centre line, and
between 125mm and 200mm above the reference plane, may only contain two closed
symmetrical sections with a maximum total area of 5000mm2. The thickness of each section
may not exceed 25mm when measured perpendicular to the car centre line.

Once fully defined, the sections at 125mm above the reference plane must be projected
vertically to join the profile required by Article 3.7.3. A radius no greater than 10mm may be
used where these sections join.

3.7.3

Forward of a point lying 450mm ahead of the front wheel centre line and less than 250mm
from the car centre line and less than 125mm above the reference plane, only one single
section may be contained within any longitudinal vertical cross section parallel to the car
centre line. Furthermore, with the exception of local changes of section where the bodywork
defined in Article 3.7.2 attaches to this section, the profile, incidence and position of this
section must conform to drawing 7.

i don't think the 25mm thickness means it can only be between that measurement, i think that just meas the thickness of the pillar can be no more that 25mm. What curve you put on it i think is up to you? and the 10mm radius just refers the join allowed from pillar to front wing

mind you, that rule you posted for some reason confuses me too many engineer sentences, longitudinal vertical cross section etc etc lol

US GP 2012 - Friday Free Practice

[raymondu999]

Not sure if this should be more appropriate here or in the team thread.

I just noticed that McLaren's pit light "lollipop", on the back - has green/red lights indicating which stations are done & dusted. They don't activate all at once - they activate LED by LED. The one on top is for the rear jack, then each of the 4 tyres, then the one on the bottom is for the front jack. The one on the side is seemingly for the sidejack, in the case of a front wing change.

Does anyone know how they're getting activated? I don't think the "lollipop man" would have quick enough reactions to respond to that and turn those green. Any ideas?

[allstaruk08]

I'm guessing the triggers on the wheel guns will have a electrical connection to the pit light system and the jacks will have a wireless connection based on when the rear jack is dropped when they pull the trigger.

that front wing has had elements removed. and they still picked up downforce! WTF.the new wing looks much more simple. yet Hamilton Smashed that last race. goes to show 20 element front wings are not as important. can anyone tell me why removing those elements gave them more D/F

[Nando]

Maybe it helps feeding the rear of the car with either more or better quality air which increases downforce at the rear which in turn allows them to run the front wing at a slightly more aggressive angle?

No idea tbh.

[beelsebob]

Neatly demonstrating the falacy that so many people on this forum fall into. More complicated does not equate with better. More elements does not equate with more downforce. In fact, generally, it equates with more drag, and needs to work oh so much harder at producing downforce to make that work.

No "yet" is needed, in engineering, simple things are often (usually in fact) the better solutions.

goes to show 20 element front wings are not as important. can anyone tell me why removing those elements gave them more D/F

because the wing is better designed. Here's an example profile for a wing, it's got 100 elements, it's pretty obvious why it doesn't generate more downforce than the current one:


The answer really is as simple as that – "zomg it has more elements" is not "it must produce more downforce". The key to more downforce is designing the shape cleverly to cause more air to change direction. That's not simply a matter of adding more elements.

A lot of assumptions you make though.
The FW very likely has LESS downforce.
There might be a NET downforce gain, down the car OR... same down-force but more aero-efficiency so they can turn up the the rear wing. Only Paddy Lowe can tell you.
