Technical Regulations for 2009-2015

"Based on the information we have received from most of the teams, we have decided to keep the same tyre dimensions (in 2014)", Hembery said."

So, you're right, Holm. I somehow still had in mind that Pirelli wanted to widen the rears...

[SectorOne]

the cars are traction limited(=not at full throttle) from the start up to ~100km/h. Above this speed, KERS is activated.

But it should be said that they are also gear limited up to 100km/h.
So being able to put in second gear at now 80km/h should give some benefit i think.
If we just took a ´13 car and did starts with the two gear limits.

Wind Tunnel testing has been restricted to a maximum of 80 runs per week and a maximum of 60 hours of tunnel occupancy with only 30 hours of "wind on time". Still 60% scale maximum & 50 m/s airspeed. CFD is restricted to 30 Teraflops per week.

[Saribro]

CFD is restricted to 30 Teraflops per week.

That must be off, or oddly phrased causing misunderstanding. Sauber's 5 year old Albert 3 (assuming peak performance) would have blown through that budget in under 3 seconds (though I vaguely recall them not having their computing in house anymore). Top line graphics cards today even do 0.7 to 1.5TFLOPS double precision, so that would make for less than a minute's work.

30TFLOPS average sustained performance as an upper limit seems to make a lot more sense, even if puny by today's hardware capabilities.

You can go to their site-> Racecar Engineering and sample the latest magazine and see the article for yourself. I'm sure it's not a misprint and their information is correct.

Wow, 30 terraflops is nothing, get 150 decently high end workstations and you hit it!

This part seems more useful:

3.4 CFD Teraflops Usage is defined as the average number of teraflops of computing power used for the purpose of making Restricted CFD Simulations during the Aerodynamic Testing Period.

As seemed more sensible to me before, the 30 TFLOPS is the maximum allowed average computational throughput.
It's still a fairly small number by today's hardware standards, but at least this way it sounds sane.

[Owen.C93]

Mike Elliot of Mercedes was talking about this. Is a very big downscale for the big teams who used to run their tunnel 24/7.

I asked current F1 Aerodynamicist is 30TF sounded correct and this was his response.

[Kiril Varbanov]

Yeah, that's a small amount. I haven't had the time to read the entire sporting regulations apparently (thinking they are still under construction), but now I did go over them. Clicked the X on the browser tab with the bitter expression of a person who doesn't like lemons, but ate about half a kilo. The sport is SO regulated and the time for testing and experimenting is becoming less and less .... Ridiculous situation. Even the number of bottles of water and towels is regulated ...

[Ogami musashi]

Autosport plus has a feature about some proposed rules for the 2007 Overtaking Working Group projet that led to the 2009 and 2014 aero rules. And it seems Fan cars were envisionned...i've never heard of that. Anyone? (i don't have a subscription so doesn't know about the article); http://plus.autosport.com/premium/featu ... les-world/

[SectorOne]

Yea there was talks about that for 2014 but that was shot down pretty quickly after it came out.
I believe it had to do with the fear of too big of a difference among the team´s floors in terms of downforce.

[Ogami musashi]

Are you sure you talk about Fan cars? Or ground effects cars?

[SectorOne]

A fan car i think is technically a ground effects car if i´m not mistaken but yea, unless my memory has turned to scrambled eggs i think they talked about a fan.
