Flex in non-flexible wings
How do the Bulls grind off the front wing endplates and still pass the 100kg static load tests ?
Or , perhaps more appropriately , how is it that nobody else can copy this trait ?
Charlie is saying they're ok .
Horner is sounding all bored with the questioning .
And , everyone else is left wondering how Newey is flexing the rules , enough to grind the endplates so much .
It seems kinda weird that nobody else has worked a way to do this , as the downforce at speed must be far more weight than 100kg .
Surely , these brains should be able to configure things such that they would not flex until they were above the required weight applied , and only then to a certain amount .
So , what's really going on here ?
If they aren't flexing the front down , the only other way is to lift the rear end , and that doesn't seem likely .
But , Horner seems a bit too happy with talking about the mysterious front end .
And Vettel said earlier he liked the rear .
Are folks looking at the wrong end of the car ?

Most probably a combination of:
1. front wing CF layering allowing the wing to flex more after the 100 kgs load is passed
2. the front wing is under much more than 100kgs of load when at full speed on the track, also the aero load is distributed on the whole surface of the wing unlike the FIA punctual static tests which means the wing will behave differently then under static testing
3. suspension setup
4. Excellent aero means that they can run much more front wing then the rest without unbalancing the car, which in turn means that they will do great on medium and high speed twisty tracks
Conclusion is that the rest of the grid need a lot more than KERS to beat them to the flag.Michael Schumacher The Best Ever F1 Driver

i was going to say something not quite so clever and technical as Ioan, so i'll say i agree - to me it would seem if the static load is on the end of the wings that doesn't replicate the uniform pressure across the wing imposed by the downforce. i'd imagine that there is something very clever in the construction that menas when the load is distributed it flexes, but when subjected to a load at the ends it remains stiff. plausible?
"I" before "E" except after "C". Weird.

I'm enjoying it immensely. No one's got a clue - after 18 months or so - how the Bull's are doing it!
All other opinions are wrong....

Very clever solution by Newey, and most probably difficult for other teams to implement without a large change in design philosophy, cause I do not believe for a second that Ferrari and McLaren could not build a wing that behaves similarly, it's just that their cars would not be any faster with it cause it would most probably unbalance their cars (front to rear downforce).Michael Schumacher The Best Ever F1 Driver

Just a theory, ironically enough I was actually thinking about this today at work (shut up, works boring) and I'm wondering, the static load test pulls the wing end plates straight downwards right? What if the wing doesn't flex straight downwards? Maybe they flex on an angle, down AND backwards? So they only flex when it has windspeed of 150km/h plus pushing the wings backwards as well as downwards with the downforce do they flex, rather then just straight down as in the static load test???

3 -I guess it's possible , that the suspension might be involved , but that would have to also be an area worked hard by all the teams , so to be so far ahead seems implausable .
4 -The "excellent aero" seems to be the advantage they gain by getting the wing closer to the ground , so they can channel more of the incoming air to the right places .
I think , though , that part of that advantage is that they can actually run slightly less , not more front wing , as they seem to be flexing down , increasing the angle of attack .
This might explain why they haven't needed the KERS at the start , because they have a slipperier car at lower speeds off the line .
Once the car is at a speed that's equal to the speeds and downforce created in those medium and high speed twisties , the nose is somehow able to squat down and create more efficient downforce .
This , coupled with better weight distribution , due to optimizing the weight of the missing KERS , had them miles ahead , figuratively .
Those of "questionable knowledge" will be the scientists. You might think that rocket science is hard but: Rocket Scientist: Someone who understands Newton's Laws of motion and basic chemistry....
