Technical Regulations for 2009-2015

[WhiteBlue]

The actual trend in research for overtaking is not in going for a venturi or not, but is having devices that clean the wake.

Interesting information Ogami musashi! +1
How would an optimum device for wake cleaning look like?

There're several designs explored by indycar's proposals in 2011 that involve creating a strong upwash straight after the diffuser. This was called "mushroom" device because the upwash was in fact two counter rotating vortices pumping the turbulence out of the diffuser. The idea is to get the turbulences above the following car. This was also the idea behind F1 2009 regs. For F1 is relied a lot on the rear wing suction hence when teams clawed back diffuser downforce the concept didn't work as well. For 2012 indycar's proposal several manufacturers offered a device within the diffuser to create the mushroom.

Another concept explored is the pulsed jet to creat counter annulling vortices.
I think Plasma use could also do the trick.

IMHO this is a far better solution that scratching heads' thinkings about were to produce downforce especially in F1 were teams are exploiting every hole they can.

But more, the specification of some parts would do a lot of good hence why i regret that the spec floor (IIRC it was the end part of the tunnels that was supposed to be spec) is ditched.

Lowe revealed that the teams have already decided that tightening exhaust restrictions further next year is unnecessary and would only push up expenditure ahead of the major regulations shake-up in 2014, when the new V6 turbo engines are set to feature a single, central exhaust.

“It has been discussed at the TWG (Technical Working Group) whether there should be a further constraint this winter,” he confirmed. “All the teams agreed that it wasn’t necessary or appropriate, and to keep developing for another year with sight of 2014 when it will all change again anyway. One of the big drivers of cost is change itself, so if you were to change the rules and change them again it would only cause teams to incur further costs.” Link

Are there any major revised changes to the regulations next season? Or do we expect to see the more or less the same regs until 2014?

The only significant changes I know of are
1) Covers allowed over the top of the step noses.
2) no secondary effects of DRS.
3) No use of DRS outside the DRS zone even in practice and qualifying.

I can kind of understand that most of these regulations are to either save money or for safety but they sure make the sport much more boring.

This is because they hamper the most attractive thing with F1: Technological apex.

You cannot develop engines, you cannot develop aero with almost hideous restrictions. You need to share many common parts among cars.... So what is left? F1 is not pushing any technological/scientific boundaries anymore and that is just sad.

I remember people talking same things in 2011 regarding 2012 rule changes. As it turned out, changes had massive effect on downforce levels with no ebd and further wings stifness and flex constraints. The end result was RB loosing more than 2s in quali in Australia compared to 2011 (RB was the most obvious car) and on other tracks. 2011 monza pole 1:22.2 - 2012 pole 1:24.0.
Now with no unlimited ddrs things are gonna get even worse. Though i expect cornering speeds to stay about the same as this year.

I expect cornering speeds to be significantly up on last year due to the teams having had an entire year of getting their exhausts tuned to all hell.

In contrast, I don't remember anyone claiming that banning EBD would not have a significant effect on downforce. In fact, it was the primary goal of the ban. As well as to stop the trend of more and more peculiar design solutions.

Obviously I meant same speeds as at the end of this seasson not begining.

We knew ebd would have an impact, but to an extent we witnessed in 2012... dunno.

@Juzh
What I mean is that for 2013 there are no currently major changes and therefore no significant changes in cars' performance are expexted. Of course those who had got to grips with Coanda exhausts will refine them, but I don't thin there's much to gain combined with limitations on engine/throttle mapping. Those who lagged behind will try to catch up but it'll be difficult without already valid and tested data. New Pirelli tyres may bring some new challenge but ATM we can't say.

Hi everyone,

i think that everyone knows about Toro Rosso and Red Bull have the same founder, Dietrich Mateschitz. After what happens in Abu Dhabi and Interlagos (Toro Rosso leave the road to the Red Bull cars even like a lapped car do), i'm asking myself what the regulation says about team cooperation.

i know that is illegal have more than 2 cars for team, but red bull is as if has it in this way.

what do you think about ?

Red Bull and Toro Rosso were already made to separate their design teams, and stop sharing aero data, but there's probably near no regulation you could actually do to stop them moving over for each other on track.

WMSC decision: 2014 aero regulations reverted to 2012 spec.

Probably the dumbest thing they could possibly do.
My excitement for 2014 just died.
