Or more likely, they probably just didnt use the system today.

Something like this:

Reading scarbs' twitter reminded me of the existence of a minimum radius rule on rear wing cross section ( the one that caught out Sauber in Oz last year).

Wouldn't this rule ban any shape like that?

Interesting...

FIA Technical Regulations Article 3.10.2:

With the exception of minimal parts solely associated with adjustment of the section in accordance with Article 3.18 :
- when viewed from the side of the car, no longitudinal vertical cross section may have more than two sections in this area, each of which must be closed.
- no part of these longitudinal cross sections in contact with the external air stream may have a local concave radius of curvature smaller than 100mm.

I think you could successfully argue that the concave radii in a void like that are not in contact with the external flow. If that was rejected, it would be impossible for the section to both be closed and to have concave radii that aren't exposed to the external flow, so the second part of the article would be redundant.

Slot does not have to have curved edges, could be square / angled...

A square edge is just a curve with (close to) 0 radius.

how you do not understood what is the point? when DRS are open air come through the hole what are open, and this air go through RW and exit through this holes who are position on top RW, and reduce vortex which are creates when DRS are open. This is benefit,and this is all the wisdom about this.

Read the thread more carefully. We are talking about the legality of slots in the RW.

Apologies in advance if this has already been done to death on this thread, I'm just picking up on it now.

Let's assume that Mercedes have an F-Duct like system which uses a fluidic valve system like the original F-Duct did, whereby one intake was a fairly large opening with nice straight ducting etc. to blow... something, and another intake was there to act as a signal or Switch intake.

Let's assume that the holes in the endplates are designed to allow air in only when the DRS is active. Let's call that the signal.

Now, let's assume that their top air intake above the main airbox is not for gearbox cooling, but instead is the large opening to blow "something", and that this is somehow ducted to both above and below the beam-wing via a fluidic switch controlled by the endplate holes?

When DRS opens, signal sends main air feed to behind the beam wing, drastically reducing drag by "filling in" the low pressure section behind it. When DRS closes, a nice focused stream of air is then fed above the beam-wing to aid downforce.

Sound too wacky to be true?

Remember that Mercedes F-Duct did not have a shark-fin connection. Instead it featured "nostrils" on the rear wing, and it was suggested that the signal air may be being ducted up the endplate(s). If so, they already have experience in this area.

Just my thoughts. Please dissect at will.

is it just me or does the sidepod seem more sculptured and refined now?~

Can anyone tell me why they're using Cinturato model tyres?

I thought they ran P-Zero branded ones, or are they just plugging another model name at the moment (sorry, bit off topic!)

[Schurcedes]

This year's wet and intermediate compounds feature the Cinturato branding IIRC.

is that the actual duct wing? it doesnt seem to have the chunky part like this?

Some may argue about the legality of the rear wing about the fact that the wing should only have 2 elements(remember Ferrari tried introducing a 3rd element at fp in Barcelona claiming it to be a part of the end plates) the slots on the rear wing are not actually on the rear wing but actually on the inside of the endplates so that argument would fall flat on its face..

at the end i think that the F-duct is over hyped its major benefit would be in wuali as in the race unless drs is used then the entire device is basically USELESS

Its hard to tell due to the different angles but MAYBE JUST MAYBE mercedes are blowing the diffuser or atleast parts of it and also blowing the brake rear ducts (like mclaren and ferrari)

[Pup]

Sound too wacky to be true?

Not to me.

The exposed ducts are most likely the switch, with the major flow happening elsewhere. Think of the old f-ducts - the wing covering and uncovering the opening is analogous to the driver covering and uncovering the old fluidic switch control with his hand.

My guess is that the intake is the secondary inlet behind the main air intake, and the flow is going through the duct that connects to the beam wing. I think the beam wing is what's being blown, since it's outside the rules limiting the rear wing itself. Where the pilot flow from the wing goes, I'm not sure, but it could be hidden under or within the main duct. Someone mentioned two ducts were visible? I haven't been paying close enough attention myself. Anyway, I'm guessing that there's a fluidic switch, similar to before, under the engine cover that directs the main flow either through the duct to the beam wing or simply out the engine cover exit.

But I'm wondering now if the DRS ducts aren't more like release valves. That is, if there is a wing being blown, there will be some back pressure in the system. The DRS holes could then be like release valves that lower that back pressure and so decrease the wing blowing beneath whatever threshold causes the wing to stall.

Oops!

Sorry Pup. Should have read the whole thread before I opened my mouth, but hey, great minds think alike eh!

But it's still pronounced Herbs (i.e. the H is not silent!)
