Mercedes GP W02

[Richard]

Almost as if Merc struggled to get it to work so they want to get it banned in case a rival team succeeded.

The FIA simply need to require the front wings to be closed sections just like the rear wings. It woudl be a mere closing of a loophole, it makes sense to require all wings to be closed sections, doesn't it?

Although Brawn has history on this with the DDD when he was part of the overtaking working group that developed the rules intended to limit diffusers.

Did Brawn not bring to the OWG's attention there was indeed a flaw in the DDD rules?
Only for Theissen to veto any rewording of the law....?

Was it really Theissen? I've never heard anything pointing to him as the source of it. However I also heard stories that (though I don't know true or not) that Renault (who incidentally was under Bob Bell in terms of technical direction at the time) and Red Bull brought illustrations of a slotted diffuser concept; which were shot down. I remember hearing also that Brawn, while he did bring the loophole to the table, he brought it conceptually rather than through illustrations. Red Bull and Renault were shot down whilst Brawn wasn't. Or some such story.

There is already a w03 thread.

And they can improve what they want, its stupid to let the teams see what your doing for the comming season.
BrawnGP didnt show their dubble diffuser, if they did Jenson would never won a championship.

For the Regulation all I can say is that wings dont have to be closed. Mercedes used a front wing with openings several times this year.

[Cocles]

Eh, did any of you read the article? Martin Whitmarsh said it was already too late for McLaren and the other teams to have something like this going before the start of next season. Mercedes is fine.

[Paul]

I'm sure everyone has more than enough time to drill a few holes in their front wings if they want to. Neither should evaluating the concept take much time.

[marcush.]

word is it seems to be hard to model such ducts in a windtunnel environment and maybe as well in straight line testing .So you need to build experience on track.

But then we will see lower noses next year ...will the behaviour compare usefully to what they have tested already?

[Paul]

For Newey it should be enough to close his eyes and imagine the flow, for others CFD model might prove sufficient to say if a tunnel model is necessary.

[PlatinumZealot]

we will soon be on three hundred pages of legendary crappiness (this thread). highest thread count ever for F1-tech?

Thats what they call playing hide and seek. Which Mercedes obviously has fail to play.

Don't forget McLaren had a poor pace at testing this year, throw the car away and started from zero to develop a car in 2 weeks time!

And thats the car which they have been fighting for the championship this year!

So believe me, they have plenty of time!

So the answer is "Whitmarsh was fibbing?" I just don't buy it. We argue incessantly on here over which team gets the smallest details right. Yes, of course any team could "drill holes" in their wing and send it off to the track, but the idea that such a wing would be equal in performance to one that's been developed for months is ludicrous.

As for McLaren, they hardly started from zero. Let's not forget how long it took the DDD to spread or even just the rear F-Duct.

Not really. The whole car remained unchanged from testing including the nose cone or U shaped pods.

Its just that the exhaust was causing a lot of problems & they changed the exhaust system.

[shelly]

As marcush correctly wrote, testing tiny ducting in scale model in wind tunnel does not give reliable results. You need 1:1 testing to evaluate that.

CFD? I am not sure what kind of fludic switch they are using (if they are using any), but if it works with turbuklent transition cfd also may be erratic.

[dren]

This will likely help out Mercedes more next year with the lower nose section.

I think its within the rules if full scale models of just the FW+ tires are tested (F1 parts/part combination)..but would not give a complete picture of the effect..
