The proposition is to lower it from 15cm to 7.5cm. How will they do this? Different shaped nose cone? Longer hanging struts? Or a return to V keel?

Any speculation or discussion is appreciated!

Chris

Well remember the centre section of the current wings is much lower than 15cm so the struts wouldn't have to be too much longer so they could keep current nose/suspension designs.

I think...

Then we have the actuators for the up-down part of the wing to fit in the nose somewhere.

It depends what the actuators are made out of. If the FIA wanted to be innovative as they believe they are, they would allow Shape-memory actuators which would take up far less room and be lighter than anything hydraulic.

On motorsport-total.com (which by the way seems to be a good site) there's an interview of ross brawn on KERS and 2009 regs, and in illustration a rear wing CFD from renault.

I don't understand german, so i translated it via prompt and it suggests it is a a rear wing with 2009 regs, containing 3 elements, i heard some time ago that going back to 3 elements was considered...

By the way, here's the picture:

its my favourite German site

The new aerodynamic for 2009 was prepared by CFD simulation.

very interesting interview btw

Ogami, do you have any info on how the nose shape is going to be effected by the changes? Maybe Scarbs?

Thanks!

Chris

No i haven't sorry. In case some of you didn't read the interview of ross brawn, the point is that honda will surely design two cars, one with the KERS the other without it because it seems the KERS is not necessarily worth the weight, something Scarbs told us few months ago.

that's not exactly what he said. he said that he belives all teams will build cars that can run with and without KERS. they will try different versions and havn't decided if they have batteries or not. but he spoke about batteries as a field where they work with an external partner.

He also said, in terms of packaging that you wouldn't be able to actually see the KERS from the outside. So, the only thing that would change the look of the cars is the new aero configuration. I can't see the nose being any different from now (there are no rules which stipulate it) but it just depends on how the CFD/wind-tunnel results come out.

We may get more low-nosed cars next year (I hope so!), with more variation in design.

What I want to know, is how streamlined the bodies will be. Can they be as sculpted as now, just without winglets? To what degree will they be similar to todays chassis'? Oh how I love new regulations

There has been some contradictory indications. Stephano domenicali said the new aero regs would allow for more variations but i think howett said that the aero regs would be even more restrictive than now.

Willis said the bodywork would be adapted to make up for the loss of winglets and i don't recall who said that the sidepods had a minimal cross section area from the inlet to the rear wheel so that no coke bottle will be possible.

Nothing has been said on lowering the sidepods and nose again so i don't know...We'll have to wait again..

Do you know if any of the teams are planning on running their '09 cars on track before winter testing? I don't want to have to wait until the end of the year to get an idea of some of the designs! Has no one released any preliminary conceptual CAD models or even sketches? I'm very eager to see them.

Ferrari hinted they could run the 09 prototype around november.

We'll have more information when FIA will update their regs. There's a WMSC meeting the 30rd june, according to willis this is the deadline for publishing the rules.

Someone on the autosport forum told me that the FIA rules are automatically updated via a diffusion list.

Well its almost obvious that the KERS system will not be actually visible, but it will be noticeable as it will take up more space in the rear end packaging of the car for sure. So that will be one of the visible differences along with the changes (restrictions) in the aero regulations.

About the streamlined bodies, IIRC I read that the sidepods will not be allowed to be as undercut as they are today, making them a bit more 'boxy' shaped.

Maybe a return to the 1979 type sidepod that were tunneled?

I don;t know how they work, but I have seen them in the 1979GP mod for rFactor. If the current open is enough to cool the engine, then there is going to be alot of unnecessary space at the opening.

I am very excited to see how the teams maximize the new rules!
