Renault R31

[forty-two]

Interesting jack they're using there. Perhaps this is connected with the apparent lack of a metal hook plate as was normal for most cars in the last few years?

It's funny, all of us was seeing Barcelona and Jarez FW front view as the same (including me). Now look at it! Do you see the differences? Are they subtle? There is slightly different angle in photos, but if they would be in the same perspective, then differences should be even more visible.

Interesting, that left and right FW cascade looks like they have different arrangement.

Well spotted. I had no idea they'd changed that much between tests either. The pace with which Renault have been confident enough to make changes to their front wing is quite impressive. They're clearly evolutions on the same theme though.

It just looks like they're at the point, where only slight modifications to whole concept are possible, because it's very refined already. More spectacular changes would be possible, I think, only with new approach to whole problem.

Still convinced that the differences we see are due to the different angles/perspective, apart for the 'dummy' cameras which are missing in Jerez 1.

Also both Jerez pics are from a moving car, which could explain the narrower gap between the 2nd and 3rd elements closer to the center of the car (although the wing is not flexible, of course! )

No.
'The Barcelona 3 FW' shown by madly is the new wing witch has these endplates: (top)

The first R31 FW is more like a pre-Singapore 2010 wing...

My point was that I believe that the highlighted areas in the pics are all identical.

That's the thing, I was wondering about. Why it's not flexing yet? Is this so hard to replicate?

Well I am confident that the wing is flexing... It was a (poor) attempt at an ironic comment about the current situation where wings are rigid when tested while everybody can see that they are moving at speed.

Sadly, Madly didn't just highlighted the most important details and no, these FW are not identical. the differences are in the endplates (like I showed above), and the two upper wings.

look at these 2010 FW: these are a pre singapore GP FW (top) and the singapore GP FW



forget the endplates and concentrate on the the upper wings. they are differently spaced in their inner side... this is similar to the jerez and barcelone 2011 versions...

[madly]

I don't agree with Onch. Barcelona photo is taken from higher plane than the old (Jarez) FW photo. So there is different angle. But in reality gaps between particular wings (flaps) in FW are bigger, than in Barcelona photo (higher angle shortens gaps -> perspective).

I don't believe, that FW is flexing in such a way, that gaps start to be smaller when they are under speed pressure. Not so much. RBR flex FW moving entire FW down, not particular wings (flaps) and closing gaps between them.

There is very little photos of R31 from day 4 in Barcelona, is somebody has other photos, please put it here, maybe it will be some more change evidences.

What about differences between left and right cascades? Poor photo quality and imagination or it's something in it?

[Onch]

I stand corrected... It was indeed the higher point of view on the Barcelona shot that made me think it was just a matter of perspective.

No specialist in flexible wings, but I guess the teams try as much to have the wing moving as a whole, as to modify the relative positions of the differents components?

As for the assymetry between left and right I would be surprised if that would be the case. [waiting for Blackout to prove me wrong... ]

[mith]

I thought wings was flexing to get closer to the ground to generate more downforce rather than to change arrangements between particular flaps and winglets. I never saw Renault wing with sides pointing to the ground like on RB and other who managed to copy it.

[Onch]

I guess the top teams will have 'learned' during the winter how to make flexible wings like RedBull.

[mith]

As much as I want it to be truth, the only new flexing wing I saw until now was on Lotus T128, so I'll wait for some photos rather than take it for granted
