Toro Rosso STR10 Renault

Monaco has a low drag penalty due to the low speeds. A good chassis will show there. A good driver, too. As has been stated, it highlighted the driveability issues of the others compared to the Mercedes.

First time I saw a structure element passing through a part of an engine, very interesting solution - probabaly get some gas flow stabilization out of it too.

why would it go through the exhaust? it's welded on top of it, it's not passing through it

In this case, the exhaust is a structural element. Rear wing forces pass through the carbon post down through the exhaust pipe.

And i belive there where is reforcment of exhaust its also connected on top of gearbox...

Look on this pic to see what i mean..

That is very strange! I wonder why they have done that instead of the inverted Y-lon that other teams are using?

[daveyrace]

They must have a reason for putting the support through the exhaust like that? I put an overlay of the part from the poicture aleks_ader linked to on the picture via Amus from above. So the position of the part can be seen. What we need is a shot straight up the exhaust

What is interesting is that the part appears to be clean, i.e no exhaust gasses have passed over it, so it must be shielded. Perhaps the exhaust drops over the top of it and has an integral fin/shield welded in. Perhaps they just want a clean flow of air round the outside of the exhaust from under the engine cover?

Bear in mind that the vertical post is also connected to the engine cover which might have some proper support underneath to carry the loads. And that the rear wing end plates are mounted to the floor, which will carry a very large portion of the downforce.

Exhausts really aren't made for any off-axis loading...

(I don't think it's the case but) Let's assume the pylon goes through the exhaust: it occupy space inside the tube so less hot exhaust gases pass through it.
Does it help/affect engine performance?

I wonder, if the center support actually does go through the exhaust pipe, if the heating of the center support by exhaust gasses causes the support to expand causing the center section of the rear wing to move upwards slightly relative to the outer edges, which I believe are fixed in position via attachment of the end plates to the floor?

Possible?

It sure wouldn't help. It would be a (minor) blockage for the exhaust flow, basically increasing the backpressure seen by the ICE/turbine and reducing output power.

Does anyone have any pictures more from the side so we can estimate the distance between the support and the end of the exhaust? Regulations say the last 150mm of the tail pipe must be unobstructed so if the pylon is within those 150mm we can end the speculation immediately. If not, then it would be allowed by regulations but still highly unlikely that there is any structure passing through the exhaust imo.

[techF1LES]

Instead of a round design mimicking the shape of the exhaust, the vertical attachment structure (dotted line) goes inside the big pipe and is attached to the car’s deformable rear crash structure. There’s no doubt that it’s a lighter solution and one that doesn’t interfere with engine performance.

[ringo]

I think it would contravene the rules if it did. secondly the heat would be transmitted through the support and would cause damage or burning or too much flexibility.
what i think this design is is the exhaust pipe is the support itself. If you look slightly behind the support you see a band of CF. That band is where the strength is coming from.
That pipe is more than enough strength to support a little 750mm rear wing.

Anyhow, this car seems just as good as the redbull, and i believe they have done a better job with the renault engine.
