This is a shame...

I'm sure the wing they ended up using passes the FIA regs but I still cant believe that that amount of flexing could possibly be legal, it would just be a joke. I wonder what Red Bull think of the wing behaving like that, I imagine they were laughing pretty hard. Lol

I still don't see any authoritative source saying that. We've seen a good source say the Korea one passed, and that this one is more flexible still. They don't need to pass any tests to use it in practice, so we have no clue really if it's legal or not.

Does scrutineering do tests after Qualifying? The Saubers in Melbourne were disqualified only after the race (rather than after qualifying) which is why I asked.

No, the cars are monitored from the moment you leave the garage in Q1 all the way through until the end of the race. After qualifying they're taken to the garages, and seals placed over them so they can't be tampered with. They are only tested for compliance after the race.

Alonso quoted on TV saying they're running the more flexible wing.

Oh? The BBC commentators were stating during qualifying that they were running the older less flexible wing because the oscillation had nearly destroyed the wing. That still doesn't mean it's been tested though – the parts are tested after the race.

As an aside – I wonder if the wing oscillating like that was putting too much load through the nose/suspension too? In the past we've seen the Ferrari be able to really aggressively take kerbs, yet Massa's suspension collapsed with what looked like a (relatively) minor hit today.

Whereas in the interview afterwards Alonso said it wasn't the old wing, it was still the new wing but they'd made some changes overnight to stiffen it (more likely something to damp it tbh)

@crucial xtreme: you state as obvious that the massa wobbling wing is the same used by alonso in korea and you make a big mistake, because you do not consider that they can have the same external shape and a different layup. So the general patronizing tone of your long post is out of place.

@myurr: It is quite common to use the same female mould for two different wing structures; and probably this is what has happened. So two wing can have the same external shape but different flexibility behaviour. If this is the case, we do not know if both layups are rule compliant, or just the korea one

Plus that wing behaved OK up to what, 280Km/h? only then it started oscillating like that.

The properties of this carbon fiber piece will be different in real size and in any 60% model. There is no way to make a model with the same stiffnes/flexibility in all directons, much less to match resonant frequencies. Plus with wind tunnel limited to 60% size, neither ground effect, nor the actual speed of the road can be exactly simulated.

It is perfectly possible that they did not know that this would happen at a certain angle of attack and approx 300Km/h. The only way to test for it is to run it in the car... exactly what they are doing.

Note that there were no wild oscillations on quali.

On speed channel in the U.S., The commentators pointed out during FP2 that the Ferrari's were wearing an old wing while the new one was FIA tested. By the end of the session the commentators said Ferrari passed the test, then here comes Alonso new wing back on, so, I'm assuming the wings were tested by the FIA during FP2

Massa's suspension failure was worrying. I wonder if Ferarri's much talked about aggressive approach to 2012 is following the Newey route of everything down to the minimum. Hope the 2012 car isn't as fragile as the RB6.

Parts are tested all throughout the race weekend, and before FP1.

24) SCRUTINEERING
24.1 Between 10.00 and 16.00 three days before the race (four days in Monaco) initial scrutineering of all cars will take place in the garage assigned to each competitor.

It's good that it is breaking now.
About the wing, i don't think they wanted it to oscillate, they probably wanted it to stay down. Damping is an issue as well as the consitency of the force over the wing.
I don't think they can control this so well however. As the car would need dampers in the pylons and thus movable aero.
