Scuderia Ferrari SF70H

And to continue the floor talk, who can tell how thick it is usually and how this thickness is limited by rules?

Deleted some Team Talk. This is the Car Topic, not the Place for Team discussions. However, i sent a copy of the Original post to g70, so he doesn't have to write it all again if he wishes to post it in the Team Thread

Am I the only one wondering about the lack of spread tow cf in the flokr this year? All the floors were made out of spread tow cf for a while.

You mean TeXtreme CF? Nice catch! Yeah, it's different this year, but they still use it for a lot of other parts... Something is definitely different with the floor this year, no doubt.

Thats exactly what i meant, I just didn't expect people to recognize it by brand name.

Worked with it a bit, wonderful stuff...

Rumours swelling of a loophole that Ferrari exploit. Mentioned by a few new outlets like Sky, etc.

https://thejudge13.com/2017/03/08/ferra ... ey-did-it/

"The pictures included in this article show us that the carbon part we thought were side pods actually aren’t. It is a structure made to regulate the airflow towards the real side pod. As you can see, the actual side pod is approximately 30 cm behind the carbon flap. What the front view did show us, was that the side pod entrance was rather unusually located high up.

Of course, by now Ferrari’s rivals have figured out just what Ferrari’s design team were intending to do. Under the watching eye of Simone Resta the Italian team found a loophole in the regulations. Personally, this is why I love F1. Loopholes mean somewhere someone was smarter than the one who came up with the rule.

The new regulations for 2017 promised us more aggressive looking cars than the year before. To that affect, the FIA incorporated rules about the V shape of the front wing, the way the end plates of the rear wing should “flow”, and under what angle the side pods should be. Paragraph 3.8.8 says that that angle should be 75 degrees. These rules are meant to give the cars a fast, aggressive look when viewed from above.

These rules are for aesthetics rather than ideal performance. As a matter of fact, aerodynamic engineers hate the rule, if it was up to them they had gone for a rectangular design for the side pod. A side pod with a 90 degree angle would have a smoother air flow relationship between it and the various air splitters ahead. Further, the general airflow performance around them would be optimised wholesale.

This is where the new loophole comes in. With the birds eye view, it’s clear to see how Ferrari made its actual side pod under a 90 degree angle. The carbon work in front (but still incorporated) of the side pod is set under a 75 degree angle, thus following the rules. This enables Ferrari to make their side pod smaller than they appear on other cars. And it gives them more room between the barge boards and the actual air intake of the side pod. All this should be able to generate a better airflow towards them."

Can some educate and explain the 75 degree and 90 degree difference?

No expert here, but I think it will be similar like the angle of sunlight hitting the Earth during summer and winter.

[PhillipM]

That's not exactly a loophole that hasn't been exploited by other teams as well...it's hardly rumours, it was an easy one to use.

[SiLo]

If you look top down on the car, its the angle from the centerline of the car outwards. So 90 degree is completely perpedicular to the driver.

The sidepods should be swept back slightly (75 degrees).

About the floor, the heat pipe idea seems the most logical and as someone said it could be very well used to heat the beginning of the diffuser (or the sides) in order to reproduce what EBD was doing. The heat pipes will go to a heat dissipator which will be used heat the airflow. A question for the aerodynamic specialists: would 80 or 90°C be suffisant to energize the flow and reproduce the famous EBD effect?

[PhillipM]

No, you don't have anywhere near enough conductive surface area there to heat that volume of airflow, it's not logical at all, you'd have to run a large aluminium panel there at the least, if not finned too, exactly what you don't want there.

The most logical explanation is they're running hydraulic pipes through the floor to dissipate a little heat and for better packaging. The temperature strips are there to check the floor isn't getting so hot that it would deform.

[Gui59]

Even with a larger dissipator at the end of the pipes?

[Gui59]

And just an air channel to flow hot air going through the exhausts at the front and exiting in the diffuser?
