Dangerous front wings

The front wing endplates have to be made curved or some other solution found before one of these punctures causes a serious incident, don't you agree?

Seems a car just has to touch someone's front wing and there will be an immediate puncture as was very evident this weekend's British GP.

No.
What's wrong with punctures ??
This is open wheel racing. And you are clearly kidding about these curved endplates . By the way, it is not a shape of the endplates, but the material that makes them so 'dangerous'.

I seem to remember that several years ago, it was mandated that the front wing end-plates be made much thicker to help prevent punctures. Is that not the case anymore?
Looking at some of the front wing's endplates, it is not. I doubt anyone would agree to this. FWs are simply too important in today's F1 cars (and following next year's DDDs ban they will become even more crucial) to hurt them with some anti-puncture regulations.

It is, they are just wider now and stick out more so there's more chance of catching them.

What a ridiculous post.
And what's funny about it ??
Punctures are part of this sport.
They are using carbon fibre which is by it's nature, very sharp material.
Front wings are wider because of regulation changes which took place in 2009 and endplates are very important part of front wing. (even more important now, when all those aero toys are banned).
What You proposed is ridiculous. You can't command engineers to make endplates more curved.
BTW. Even if they were more curved, they still would have sharp edges . So maybe lets ban front wings to make racing safer

I do appreciate your magical ability to estimate the age of man based on response to your own ridiculous statement. Can you teach me this??

Only beaten by this..Hell, I say make them sharper, and we can add some nationalistic pride and ethnic diversity to F1. Replace Kamui Kobayashi's front wing with two katanas duct taped to nose , Schumi can have a couple of old German daggers, that oughta liven up overtaking. Granted, your pit crew would all be about five feet tall after the first race but you don't really need shins anyway.

In fact it is the half-steps that the people making decisions do all the time. The current FW width was set with the intention of making the car track wider - returning to the pre '98 car width. Then they feared they are too radical and dropped the second part of the modification leaving the wing only.
TBH I personally expected more broken wings and punctures, which means drivers are careful. But if a wing is sticking outside the tire margins it's easy to misjudge some centimetres.

It was an OWG thing, using the inwash.
Trouble is the wing hits the sidewall of the other car, and that's relatively thin and fragile. I don't think they can make the fwep's more sidewall friendly, whatever they do.

Which is not working at all. To make the front wing, or front part of the body - which hit the air first and is crucial to the airflow to the whole aero - bigger is bad for racing. Plus the complex endplates as development goes on by teams makes it more sensible to subtle airflow change. It should be made narrower and smaller, and perhaps thinner, and the car should make more use of underground downforce, ie ground effect such as wing car, DDD etc.The wide front wing was put in to help following -> overtaking, because the outboard parts get better air in the wake of the car in front than the central part (that they've made standard and neutral anyway).

ARTICLE 3 : BODYWORK AND DIMENSIONS 3.4.2 In order to prevent tyre damage to other cars, the top, forward and outer edges of the lateral extremities of any bodywork more than 450mm ahead of the front wheel centre line and more than 750mm from the car centre line must be at least 10mm thick with a radius of at least 5mm.
So the idea is there, but in practice clobbering a piece of CF with an external radius of 5mm at 160kph with a tyrewall rotating at something like 1500RPM is pretty much guaranteed to cause *some* damage. If you're unlucky enough to get the little tiny vane against the rim then contact of any more than 1/25 of a second is going to run the tyre off the rim. Hence what happened yesterday.
Blink, and you'll miss it.
So no, I don't think the wings are dangerous. Vettel gambled yesterday and lost; another day he'd have got away with it. That's racing.

Well it seems to work, to me. I think things would be worse with a narrower front wing, as far as following is concerned. We can see Hamilton for example being able to follow closely through a corner by taking a tighter line than the car he's attacking, getting better air over the inside half of his front wing.
The rear punctures are a downside though.

Imo more than that needs to be done, especially with the wider wings.FIA Tech Regs this year:

Like I said, a curved and covering endplate or at least something that allows cars to race close without a touch with the wing to tire automatically ending in punctures.
And how someone would not want safety to be improved is beyond me. I guess it's the same bloodthirsty crowd that didn't want seatbelts, covered track walls or the higher cockpit introduced. Shame they are spewing that lust here.

It's a bit of stretch to put me (and others posting here) down as "bloodthirsty".
Ever been on a live racing circuit to deal with the aftermath of an open wheel racing car which has flipped over several times and bounced so hard the roll hoop snapped off? I have. I would suggest that the sort of people who get involved in track work - marshalling, recovery, rescue and so on - aren't "bloodthirsty" at all.
An acquaintance of mine has a signature on his email: Life is a sequence of risks, carefully choose the ones you want to take.
As I said above - you take a risk; sometimes it pays off, sometimes it doesn't. That's racing.

I don't know where you read this...this was never planned to go back to 2meters wide cars under OWG studies. 2 meters wide cars are worse for wake effects.
The idea was simply (as pointed out) that the most affected part of the front wing in wake was the central part, thus they made it standard and widen the sides to reclaim the downforce lost by the standard central part.
Which is not working at all. To make the front wing, or front part of the body - which hit the air first and is crucial to the airflow to the whole aero - bigger is bad for racing.

I think honestly you don't know at all if its working or not neither you do know about the OWG studies results.
And i don't know where this "bigger wing= bigger wake" comes from...that's really a negation of physics...

I thought about staring thread about this yesterday but it felt too complicated. Collect examples and so on. But in reality, it seems like the new, horribly ugly, wide front wings have some kind of James Bond mechanism built in. A slifht touch = puncture almost every time. Remember Sutil touching Kimi at Interlagos last season? It was hardly even visible in slow motion. We have plenty of examples of it. First of all - the front wigs are too wide. It looks like **** and they always cause trouble the first couple of laps. They should really do something about it.Seems a car just has to touch someone's front wing and there will be an immediate puncture as was very evident this weekend's British GP.

Course i'm no expert at all. Also I know the logic of 09~ aero rule. But fact is that it's not working. early 09 it looked like it was working, cars are following each other closer than ever. But since 2nd half of 09, things have started to look bad, and now situation is the same as it was ~08.I think honestly you don't know at all if its working or not neither you do know about the OWG studies results.

Bigger front wing = more likely to be affected by turbulence. Plus, now front wing endplates are used to feed air to the diffuser, rather than to generate downforce. Therefore the complexity of the front wings. The more complex, the more sensible to airflow changes.

I guess will's power is above all. You don't probably watch the same races than me. Saying that cars can't follow each other is quite astonishing considering the recent races... And there's no wet, nor tyres in the equation, even leaders can follow each other closely without droping away.

Sorry that's wrong. The sensitivity to wake of a wing depends on the wake itself and the geometry of the wing, not its size. And in the case of the 09 wings the have a higher aspect ratio than previous wings meaning not only do they produce less wake but also are less sensitive due to the downforcing section being outside of the core wake's effects zone.
Again..you have absolutely no material to say it works or not.
Please forget Aeros by the naked eye, not good at all.
The fact they are a problem for close racing (punctures) is a toll that was accepted when the 09 rules were done.

They must built parktronics into them as the drivers have to be supermen to not make small mistakes in their judgement about distance not seeing the wing

I'm not saying cars cant follow each other. Just saying now apparently less so compared to early 09, and current situation overall looks not that different from ~08.

What have we seen in Valencia then, JB was at least 0.5sec faster than KK, or could go even more than a sec faster at one point, if not for entire race, but nothing happened. Kubica was apparently faster than Rubens too.
I'm not saying overtaking should be made too easy tho. Overtaking should remain sth that is difficult and requires skills.

Front wing endplates are now used to feed the air to the rear of the car. Some teams, like Merc, Sauber etc, direct air to the outside while others, like Macca and RBR, lead air underside. Whatever it is, its complexity makes it more sensible to turbulence. Turbulence on front wing is affecting the diffuser downforce.
Again..you have absolutely no material to say it works or not.

I'm ready to accept that I'm wrong anytime. So can you then tell me your idea on why it's not working, at least not as expected, and what can be done, instead of just attacking others like that.

There is a bit of misunderstanding of that n,n sec advantage and overtaking. When we talk about sec/lap advantage in aerodynamics vs overtaking topics it is to say that to the x sec/lap advantage of one car corresponds an amount of downforce advantage I.E if the car has the required sec/lap advantage, when he'll come close to the leading car he'll lose an amount of downforce(= an amount of sec/lap advantage) smaller than the necessary one, he will then retain enough grip to overtake.
But yet people when the see lap time advantage believe it is the downforce..of course not! It is all factors combined and then this leads to my remark: If you are driving a one way street at 50km/h and close in on a 40km/h car what will you do? ...Slow down to 40km/h then..
No matter how fast you were before, what matters is how fast you can be at a very close distance of him.
I happen to do timing on kart races, i've seen kart men with 1 sec/lap advantage (which for a kart track is huge) being completely stuck the whole race behind competitors. Sometimes you can't just overtake for there's no room for that.
And that is not true. I'm sorry.What i mean is bigger (and also more complex) wing is more likely to be affected by turbulence created by the car in front.
This had been the case for 15 years now.Front wing endplates are now used to feed the air to the rear of the car. Some teams, like Merc, Sauber etc, direct air to the outside while others, like Macca and RBR, lead air underside. Whatever it is, its complexity makes it more sensible to turbulence. Turbulence on front wing is affecting the diffuser downforce.
There's nothing new and the fact that the endplates are complex do not changes the fact that being wide they are less affected by the wake. As i've told you, the effect of wake on a following car depends on the wake geometry and the car's design.
I'm ready to accept that I'm wrong anytime. So can you then tell me your idea on why it's not working, at least not as expected, and what can be done, instead of just attacking others like that.
But the problem is that i disagree from the start, it is not working! I've told you from my very first reply.
And as attacking you...i think i've being using courtesy at a fine level. There's no other word than "wrong" when you think someone is wrong.

Posted 13 August 2010 - 12:19
How much force would a front wing withstand? If the speed difference is big enough to create a catapult effect, the front wing mounts would shatter in milliseconds. From a safety point of view, they can not be other than bad.Aren't the wide front wings make the "front wheel-rear wheel catapult-contact" a little less probable?

The front wing can take only fractions of the force generated by a car coming towards it with higher speed from behind. A small fraction.But IMHO there is a range of speed difference where the front wing is actually making the difference between to catapult, or not to catapult, however - I can be totally wrong

The end plate thickness was increased in 1996 IIRC. Really I don't see how the '08 width would make that much differenct as it is still able to touch another car's rear tyre. The drivers should know where their front wings are now. I don't think any changes need to be made just yet.

Bloody ugly overwidth things. The tyres must be a bit suss too as they seem to puncture very easily.
apparently the cars for 2009 were supposed to have a wider track, but they decided against it (WHY??!?!)
