Scuderia Ferrari SF15-T

[Crabbia]

Apologies if I have got this wrong, but it looks like that element of the crash structure just behind the monkey seat is actually fabricated from a different coloured material than the rest; if you look at the seams, the joins, it follows down the side of the structure of that colour too.

Well that was my thought if i understand you correctly. If you look at the way it follows down the side it looks to me like they have taken some heat resistant material and wrapped it or coated it over the top and down the front sides of the crash structure. I initially thought they might have sprayed it on as you can see it flows over the vertical seams of the crash struture (Look at the part just after the L that reaches down the side).

It looks to me like it is some sort of resin that was painted on. The sides of the crash structure were masked up, this was painted on and then they removed the masking. Thats the feeling i get looking at the end of the crash structure in particular.

My thought is they took the same compound and lined the exhaust with it so that the heat is retained in the exhaust till it exits. This is done so the exhaust itself radiates less heat and can allow for closer packaging around the exhaust.

Of course my whole theory is based on the assumption that things of the same colour are the same material, which is, I grant you, as flimsy as a contract with Sauber (too soon?). But based on the fact that this reddish brown colour shows up on the car where you want to control heat and protect carbon composites from heat i felt it was a solid enough assumption to propose this.

Look again at the picture mkable posted:


The reddish brownish material shows up on the upper wishbone mounting points. A critical part, that is right below the exhaust with minimal clearance, getting really hot. To me this red brown material is an insulating material of some kind.

Tin foil hat on...

Ferrari could be cheating!

Using Haemo-quantised fuel. That war time fuel - banned across the globe - stores oxygen until pressurized. The red dust you see in exhaust tip is the rust from the iron inside the compound.... Let us not even mention the toxic uranium compounds that serve latent heat absorbers in the pre-ignition phase... cheaters!!


tin foil hat off..

there's actually not so much that teams can do, in terms of fuel. IIRC 99% of the fuel has to be regular stuff that you get from the pump. the 1% is where the fuel companies are allowed to make changes. but they mostly focus on burning temps, ignition and so on. not actual HP or even economy per se. i could be just talking out of my ass, but this is what i remember.

BUT. we're not to talk about fuel here. so let's get back on topic.

i still think that orange/rusty stuff inside the exhaust pipe maybe some ceramic or other chemical coating. because if you look at the picture where you can fully see the exhaust pipe from the outside, it hasn't gotten blued like the rest of the pipe. infact there seems to be a border of bluing about 25cm from the exhaust tip.

the bodywork also stops there. i think they've added something in there to keep the heat from soaking into the exhaust tip. possibly to help hot air flow by enhancing the temp difference between inside the bodywork and outside. to create some sort of effect of the hot air charging out of the bodywork, to the more cooler air.
could also simply just be to protect the RW pilar from heating up too much.

...or could be nothing significant.

Are those numbers accurate? Because adding one liter of additives to a full tank is quite a goddamn lot. I recall having skimmed the F1 regulations on these regards and they have *very* restricted limits on some compounds, octanes and residues. And I'm talking PPM measurements.

I don't know the chemical composition of the red stuff but it is a deposit left by exhaust gasses. I have a 014 marussia ferrari wastegate and it has the red dusty residue left on the exhaust blown surfaces

that's how i remember it was. i saw that fact stated in a documentary about how ferrari prepared for the last season.
IIRC they said 99%, but it's possible it was more than that. it was a really small number anyway.
what i do know is that octane boosters are effectively banned. because the max octane number is locked at 102.

ok. so we can put that to rest

[markp]

Oxidizing of the exhaust material? Chemicals within the metal reacting under great heat? Iconel passivating oxide layer. Are the exhausts still made of iconel? Would wastegates also be made of this? Not a fuel additive at all which is very restrictive within the rules. If not on other cars maybe Ferrari use a slightly different composition of Iconal.

It can simply be red dye used in the fuel. Fuels are coloured for identification purposes.
If they maybe have their fuel containers stored with fuel for other vehicles or fuels for other purposes like generators, maybe they have their race gasoline dyed this red colour to not mix things up. I know some may ask why is the deposition of the dye so heavy, but it may be down to the flow rates and the temperatures. I'm not sure, but it does look like red dye for fuel.

To further illustrate. Lets say their gasoline is the typical colour of gasoline right... then after adding their additives they then add the colour to differentiate between ordinary gasoline and the gasoline that they have prepared for the race.
This is something that is commonly done in the petroleum industry.

More seriously, I don't think anybody can cheat on fuel. That's for sure one of the most controlled areas.

I don't know if it's possible but what about a compressible polymeric additive ?

They exist for diesel https://www.google.com/patents/WO2013135912A1?cl=en

Fuel normally is incompressible, with a similar additive you can easily cheat the flowmeter changing the density of the fuel with pressure.

This can the reason of additional fuel pressure sensor request by FIA

I can't see that in F1. Weight is everything and shell isn't going to add even 50 grams unless it is necessary. I'd go with an oxidizing reaction from some sort of additive before a macroscopic dye.

[ringo]

I think you are being too extreme. And what you say isn't necessarily factual when compared to what you are disproving.
You probably don't even need 50 grams of the Dye. And 50 grams is nothing.

[timbo]

But why do you assume that the combustion products would retain the reddish hue? Apparently the mixture is lean, temperatures are on high side, I don't think it is possible for a dye molecules to not break up, especially that red organic dyes are composed of rather lengthy chains usually. Also, dye molecules often contain groups which are easily oxidized.

I think there are two options, one is high temperature coating the other is organometallic compound. Interestingly, while manganes additives are forbidden, there's tolerance level set for lead and other possible metals like iron are not specified, so they are probably allowed (within general composition limits). So my guess would be it might be a ferrocene. It will leave reddish/orange deposits of iron oxides. The problem with it would be spark performance, as ferrous deposits are conductive. But if they manage to get around that, the RON would increase.

You are right, I was looking at the number for the Sudan family of red dyes and they only need a ~0.1% w/w concentration to be obvious in liquid. Still seems unneeded though.
