A transparent windscreen can provide some impact protection, but it would be heavy. An extreme example is the Lexan bubble canopies used on supersonic fighter jets. They are typically 1-1/2 inches thick (or more), in order to provide adequate bird impact strength at the speeds they operate at. An F1 windscreen would not need to be that thick, but it would likely need to be at least 1/4 to 1/2 inch thick, to prevent what happened to Massa, or what happened to Da Matta in Champ Car.

On a personal note, I don't think we need it. As for the spring incident with Massa, better helmets and the recently tested stronger visors should here quite a way there. Still that wouldn't solve Surtees' fatality, with a wheel bumping on the top of his head, breaking his neck. I really have no idea how to resolve this safely, apart from this windscreen idea. The problem is always that nothing "static" much can be placed above the driver's head, as he needs to be able to leave the car quickly.

And as for that HUD, that looks to me like a gadget to lure the big public into accepting such a windscreen. Nothing more, nothing less.

Merry Christmas!
As usual, I'm afraid our chief moderator is correct. The powers to be within the FIA has all gone politically correct on us.
Long gone are the days when Jacky Ickx and Pedro Rodriguez left the GPDA, as they wanted to keep racing on the old Spa.

You are correct. I was thinking of the Corvette, and the Bentley LMP1 program's wiper woes, and incorrectly assumed that the LMP1's used a similar solution as the GT cars (i.e. move the wipers out of the airflow).

Still, fact remains the wiper presents a larger frontal area when the airflow is not parallel to the wiper blade - such as when yawing/ turning. You can prevent the fluttering (stiffeer assembly/ net downforce) but You can't get rid of the drag and the flow disruption without getting rid of the wiper.

Riff raff, remember the windscreen doesn't need to take ALL of the impact. The forces/ absorption can be distributed between the windscreen and the driver's helmet. There's also new glass such as Corning's Gorilla Glass that is supposed to be a major advancement in fracture resistance (and therefore weight). Their claims are somewhat substantiated by a big investment from Apple into their technology.

I'm not hearing that wind shields are seriously considered for the 2012 rules. There would probably be a lot more talk if they were. So the report by the FiA Institute is most likely not one that calls for immediate action but considers the options. I would leave it to the rule makers to advance it to a serious regulation item. They are very good with safety issues.

Sadly, I again remind that safety is not a newfound concern of the sport. And - once again - I'm compelled to point out that these problems were addressed with a remarkably elegant, open-wheel solution over 40 years ago...

Suppose I were to show you a way to manufacture a windscreen that could do the job of an acrylic one 3" thick, but be only 1/2" thick. Would that be worth something to ya?

The drivers need not be exposed period, they could sit in an case with various HD cameras giving a stereoscopic effect. Furthermore, the camera could change it's FOV to make it easier for the driver to spot apexes, braking points...etc.

...or they could sit in the garages and drive the car by remote control.

I'm not one of these guys thinking: "Hey, F1 is about being macho" but this is becoming ridiculous.

A full canopy brings in more security problems that it solves, like fog, ventilation, heat, viewing distortions, new wipers (330 kph wipers on a curved canopy!), mechanisms for escape in an accident and sturdy three inches (or one half inches) canopies and shards and pieces of canopy flying in case of an accident.

Just imagine the air conditioning you need under a canopy in Malaysia (have those guys ever heard of the greenhouse effect? Light passes glass, but infrared doesn't).

How, in the name of Tazio Nuvolari soul, are they going to solve all of this in one season without expending half the US deficit and without bringing in more safety problems than the one they are trying to solve escapes me.

If they want to solve the BIG accident weakness of open wheelers they would be doing something about cars flying when they touch wheels.

Don't you see people what FIA is about? They spend all the time (or so it seems to me) devising new, expensive, fancy "improvements" so YOU can have "fun" talking about them.

I bet some CEO, maker of HUDs, said one day at a meeting in 2010:

"Hey, you guys, how could we introduce HUDs into the mass market?"

Then some smarty pants engineer answered:

"Well, if we could force or bribe somehow those rich and politically weak F1 directors to introduce them by regulations into the championship, in 10 years Toyota would be paying us patent rights for all eternity. We could start by pointing out the improved safety of a bubble canopy"

...and then all the eyes around the table blinked in unison... and, hey, there we are.

So, canopies it is. Sigh. After all, racing has becoming secondary. Shut, I'm going to take some laps in a kart to vent some of it.

BTW, happy New Year, you guys.

Can anyone please post an image or two of Jacky Ickx in his Ferrari 312B at the Mexican GP in 1970, audience and all please,
then we all can learn something about what racing used to be way back when drivers were drivers and...eh...whatever?

F1 - FIA: Abandonment of the windshield
Posted January 2, 2011 in the category: News , Technical Analysis
We talked about it last week and the debate was very important on this blog ( see here ). The FIA was considering the idea of a Plexiglas windshield on cars to protect drivers from a frontal impact.
However, according to information from the Italian site 422Race.com FIA dropped the idea to focus on security around the driver and the passenger with a new protection system to withstand 600kg of pressure. A test method is under development.
In principle, the idea for now is to build on the side of the cockpit two systems forms prismatic to help move a car from the top to protect the driver's helmet. A solution that could have aerodynamic constraints. One change that could occur for cars 2011.
The regulation states that, for security reasons, the FIA has the right to authorize changing the rules through the unanimous consent of the teams. However, even if FOTA seems to be aware of this change, there is no indication that a change from 2011 is under consideration. Maybe for 2012.
Relatively bad translation but the gist seems to be that the plan for a wind shield was dropped and the raised cockpit sides will be improved to protect the helmet. Storm in a tea cup as usual.

A 3 page thread counts as a tempest in a teapot in white blue country? Vishnu help us if you ever became a mod. We'd all be banned and the the forum would consist only of consecutive lengthy WB posts reposting what we all read on Scarbs' blog. I doubt you can find many posts where the members thought this was a certainty or became unduly upset. Just speculation is all. Closed cockpits are only a matter of time, IMO, and there's no harm in speaking of its implications. The aero, driver comfort and safety benefits are too obvious. Besides, too many people are playing GT5 and getting ideas...

Mods, maybe we can rename this thread Implications of Closed Cockpits on Open Wheel Chassis Design or similar.

Auto; please explain your comment? I'm not doubting whatever you mean, but a few more words might explain what you're thinking?!

Riff_Raff; how thick are Le Mans LMP windscreens? they're not that thick are they? The f1 Canopies could include pillars, so the screens themselves could be thin, with the main strength to deflect, say, a wheel (like in the late Surtees Jnr incident) from the driver coming from the pillars. As driver's have two eyes I don't think the pillar itself will pose much of a visibility issue in reality. This would allow relatively flat screens and hence no visibility distortion.

I think a "maximum driver working environment temperature" is a good thing anyway -canopy or not. An AC system might seem over the top in a sprint racer, but for a long distance event, such as an F1 race I don't have a problem with it.

The aero gains, for "tomorrow's" energy efficient formula, fit quite nicely I think.
