McLaren MCL34

[NiyolHuayra]

Any news if McLaren will incorporate those wings on the top front of the car. And the ones on the sides on top of the bargeboard area.

And what about the PU update Ricciardo had. I haven't seen any news on when McLaren will get their upgrades.

Looks, like ball being on McLaren side.

I doubt they will have the ones in the top of the car since they seem to work with the S-Duct and the MCL34 doesn’t have one... The ones in the side of the car? I’m sure they are analyzing that trend (Mercedes, Ferrari and now Renault) and will put it in the car if they find an increase in performance with it and the rest of their concept.

Found this picture by @NicolasF1i on tweeter... It seems that the team was already using a POU back in Baku, probably the new suspension is just relocating it further up?

Did not know those work with S-Duct, thanks.
For the side ones I meant those where the Richard Mille logo is on the Alfa

[Emag]

The ones on top of the nose work with the air coming out of the S-Duct, to regulate it and manipulate it the way the aerodynamicists want it to. The ones on the side (where the Richard Mille logo is) are used to direct some of the air downwards in the undercut below the sidepod or probably to generate vortices. Those are conditional on the philosophy of the car. Perhaps McLaren doesn't need those there, that's why they aren't there. It's probably a misconception the fact that the more complicated or the more aerodynamic elements a car has, the better/faster it is, but the truth is the contrary in some cases. Aerodynamicists try to minimise the number of elements they use to direct airflow. Less elements means a much cleaner airflow which leads to a much more efficient car. You can see this philosophy on the Ferrari. They have tried to use as little aerodynamic elements as possible to create their downforce and in return they have very little drag with substantial amounts of downforce. However this "efficient" design is always harder to perfect, that's why you see Mercedes, with much more complicated Aero, sacrificing some of their aero efficiency for more downforce. If Ferrari was generating more downforce with this concept, I can guarantee that they would be faster than Mercedes in *most tracks.

The problem with some of those solutions is that most of them induce “drag”, therefore the question is if the added benefit compensates for the added drag.

A friend told me that that’s the reason why the MCL34 doesn’t use an S-Duct, they found that they additional aerodynamic benefit wasn’t enough to compensate for the increase in drag... I always find it interesting that Mclaren seemed to be the only team not using one.

It's unlikely they're considering such winglets at this point. I imagine the majority of focus is centered around balancing the downforce, an area they've made decent strides in recently. The car's Achilles' heel is its front end. What they could do aero wise is go towards the Ferrari direction by further increasing the outwash with solutions such as cambered front wing endplates with tiny vortex generators, updated floor and diffuser etc; these would subsequently allow them to increase the AoA on the tapered front wing for better upwash/downforce. In combination with the POU suspension it could provide surprisingly significant gains in lap-time.

Is it me or the wing in the top has a different Y250 approach (the one below seems to be the Spain update)

We may well see an S-Duct shortly now the Renault is up to full power and the tyres seem to need more DF to give setup options.

That will be an interesting development, hopefully the added weight (I’m sure the structural integrity of the nose will need to be addressed) compensates for it.

If I’m not mistaken, the use of the S-Duct is mainly to take care of the dirty air flowing towards the underside of the nose and therefore having a negative effect on the turning vanes and front part of the bargeboard area?

Yes, just cleans up the boundary layer under the nose and dumps it in the low pressure area above.
