Red Bull RB9 Renault

Funny how people try to draw 1:1 conclusions from differently adjusted heat cameras.

That's irrelevant since the comparisons being made are looking at the difference between rims and tyre surfaces. So the Ferrari has red (hot) tyres with no registered heat on the rim, Merc has red (hot) tyres will orange (medium) rims and RBR has orange (medium) tyres and hot rims.

Even if they are calibrated differently, you can see RBR has hotter rims than their tyre surface and Ferrari the opposite.

Were the three on the same type of tyres (option, prime)? Are those pictures from the same session?

Even if they are from the same session, in order to draw meaningful conclusions other factors should also be the same. Are all of them from hotlaps? Same time of day, track location etc...

[marcush.]

you have to look no further than to the picture of the rim above1
the outer section of the rim is not painted but plain aluminium /magnesium -the emissivity and coloration of the picture will be different not according to the temp but due to different behaviour in relation to the capturing device-the camera.
Without having checked it seems possible that ferrari has their rims simply treated differntly in that area.

Nothing to conclude really! Those thermal are just for get the "feeling" how F1 tire work. That are just general assumptions and i belive that have noththing relevant according pace of differend cars.

I strongly belive that each team using own camera algorithm to "hide" crucial performance details. Even more that algorithem could be variable acording time undependialy to even more "mix" data and make it really useless (+/- 2 deg on changing specter make enought). With that in mind engineers and software developements, may they just on certain areas smoothing and makes tire curves more look like from the book aka perfect conditions. I dont even dare to think oposite. We must ask ourselves how much it would help engineers if they could just scan&analyse rival thermo data and transmit into Sunday race simulator? That it will be really silly from the high tech teams, all the most importand data on display in public could reveal literall all. Friction levels, downforce, balance, suspentiom setup (roll pich) etc.
I dont denied that maybe team aldready do that (off track spying, recording photos, videos etc.), cuz where is so big €£$ in play every thing is posible.

I saw those thermal images like bikini. It shows a lot, but it still show nothing.

So dear readers it is really nice efford to clip those pictures, but this is losing battle. For further reading is nice to read article here on F1T about that.

Now just few words about bulls. We all knew that the bulls already from beginnig had the pure, raw speed. So they was until Hungry traped inside fence of Pirellis undurable tires and they coudnt unlest the dragon out of it. After that plus spa aero upgrade (to me make Canada upgrade diff =>drag sheding) make them party, atleast for Seb. Nothing to say just brilliand car. RB5 heritage just make the history.

Red Bull have hot a rim, but Merc and Ferrari have hot sidewalls, so same same.

In general desktop computing using standard FPU/Vector measurements Intel chips are faster but AMD powered HPC clusters generally use the "Fusion" style CPU-GPU chips now and the GPU elements are dramatically faster than Intel's traditional Xeon CPU's for HPC work!

Sorry, but no - and I have to correct this because it sounds like something that has been pulled off a marketing site with people shouting "Well said!" in reply because they don't know what they're talking about and think they're getting back at someone - as is normal around here.

Very specific operations are hived off to GPUs (the dominant framework in that area these days is Nvidia's CUDA) these days but the heavy computational lifting is all still done by the CPU. Of more primary importance than even the single-threaded performance of the CPU though is the speed of the on-chip memory controller, and Intel have long since eclipsed AMD in that area. You're still moving around unbelievable amounts of data across a bus and that's where the platform really counts. There is no point shoving data through a GPU when your memory controller is the bottleneck............

Put simply, if you were building a cluster these days you can only sensibly build it on Intel platforms (I hate it, but there it is) and you'd use Nvidia or even AMD's graphics units to offset what operations you can. The above makes it sound like you can simply offload everything on to the GPU and it will magically all be faster and the CPU and its platform doesn't matter. Total rubbish.

I can guarantee you Red Bull will have started moving what they had in 2009 on, if they already haven't moved all of it. Time is money, and a lot of it, in this business.

Have I stumbled onto a "which computer" forum? I thought that this was a technical forum dedicated to the RB9.

[munudeges]

Well, Richard or whoever can re-open it from the off-shoot a few pages back. Don't ask me how this place is modded any longer.

From Reddit, the video segment of front wing vortices referred to in the Sky pre-race commentary.

So that's how Newey can "see" the aero

RB9's vortice has different "structure" and looks more consistent. Maybe this can be explained by difference in the speed and points of circuit.

[theWPTformula]

The differences between the two vortices are really interesting. I would assume both of them have been produced in the Y250 section of front wing, but whereas the F138's seems to rotate around one axis, the RB9's is very sinous at the same time.

The RB9 vortex seems to disperse before it meets the sidepod airflow conditioner. Does the vortex produced on the F138 produce more drag here?

@ aleks_ader

They are FOM cameras so I don't think the teams would be allowed to tamper with them. Yes, the cameras have a limited range and have a low sensitivity but they do give some understanding. That is what they are intended for.

The information is irrelevant and unuseful to other teams as you cannot pinpoint any performance advantage from the images but they are interesting all the same. I do believe that the link to the post about the application of Polysil on the RB9 rims is backed up by this thermal image.

We saw a shot of Vettel behind the safety car with slightly hotter rims so the thermal transmittance still works fairly despite the much lower amount of energy within the braking system under safety car conditions.

Anyone caught Webber´s stop with the camera pointed backwards?

Buckled as he´s coming in, they lift him up then drop him and the stay buckled quite severely.
It definitely looks like it´s connected to the suspension load rather then just the floor hitting the ground but i could be wrong.

I´ll try and get a gif up.

Edit:



Also notice it´s bent one direction yet during load it bends the other way.
Surely there´s less resistance in the already bent direction?
Like if you have a card between your thumb and finger and bend it slightly.
Then try get it to bend the other direction.
