Young Drivers Test 2013 Day 2 (Silverstone) - 18.07.2013

Can anybody give more info about the lines in the floor? Or have any other pictures of that area.....looks kinda odd but very interesting.

Also is it just me or did they move the exhausts further back, closer to where they were on the launch spec car?

[Carmack]

Those lines, I belive, are for temperature measurements.

it´s available for almost every temperature you would be interested in .The stuff is applied with a paint brush and changes from glossy to dull colour when specified temperature is reached .so you can actually draw a map of surface temperature distribution with this .Accuracy 1%,and the pricing is also ok .As always you be interested where and when things happen so
the question is why they are happy with this approach .
I would simply build the test pieces with integral thermocouples and get accurate time plots for surface and ambient temps
at modest investment compared to this rather amateurish attempts.

I can't help but wonder whether they are hoping that their original design for the rear airflow will work now with the new tyres...

It's not the original design, it is the updated one with the bump removed

Maybe they just want to check that a certain threshold temperature isn't exceeded. E.g. you might want the floor never to be subjected to a temperature above XdegC so you can easily paint X-temp paint on the floor and see if it changes. Much simpler and cheaper than setting up thermocouples etc.

that seems rather short sighted ...as a temperature exposure is always time dependand and a max temperature does not really tell you anything at all apart from there is this and that temp not exceeded ..
It seems odd we are talking about a few € to save compared with the information you could possibly gain in terms of reliability of data and machinery compared to this approach.
It´s not like they could not afford a few thermocouples ...the temp range in question would set you back 10or 15 bucks per piece ...so nothing realy to worry about ...it may be the labour especially when considering the time to scrape through all the generated data ..eg you´d need someone to write scripts to transform your data in useful plots for the boffins to rethink their latest creations .

nah, you can buy inexpensive interface modules and software to input the tc output right into an artsy-fartsy PC graph with dates and times and such. I did this at university for a composite cure cooling study. the tcs, modules, and software is really cheap.

In aviation we use things called "teletemps" simply little strips that are on most aircraft on areas such as gearboxes and clutch units etc. they start off white and change colour to a dark grey according to the maximum temperature reached. With these a pilot/mechanic can check the maximum temperature from a previous flight and after each flight obtained. Note however that once these teletemps change to a certain colour they do no revert back. There are also many for different temperature ranges....explains how it would be useful around the exhaust gas flow area...can easily and discreetly tell McLaren where exactly the majority of their exhaust gases are going

Is it me or is the pylons making the wing look to close to the ground??

the front wing is not on the the car
edit: you're right! i can see the tire...

Those temp indicators are to indicate the exhaust flow. I suspect they are not interested in the actual temperature of the floor, they just want to know the distribution of the hot gasses.

Having said that, the static sensors only indicate the envelope or range and have single use. Using electronic sensors gives scope to repeat the tests and see different patterns, for example different speeds for each lap.
