Do we have any more (high-res) pictures of the new front wing? I'm currently looking into updating my drawings, but I can't find any decent enough shot to figure out how the elements bent towards the footplate.

I also want to note that this update made a previous comment from me in this topic, pretty much redundant:

He probably means the concept of turning a lot more air outside the front wheel. Whereas before they didn't turn so much of it.

Gather round kids, it's time for another Turbof1's winged special!

Let's do a comparative analysis and show that Mercedes and Red Bull wing are completely seperate concepts which have no influence on eachother.

Mercedes Wing:

Red Bull Wing:

Let's first focus on the main wing elements:
http://u.cubeupload.com/turbof1/MercedesMW.jpg
As you can see Mercedes sacrifices a bit of main wing area on the outside in order to have it a nice outwards bending curve.

Red Bull on the other hand prefers to maximize close to the maximum allowed surface. Note that the edges of the 2 uppermost elements are integrated in the endplate! It also uses a strake on the uppermost elements. This strake is very important in managing the airflow around the tyre. In short red bull uses more of an upwash solution then effectively an outwash one, although the latter mentioned strake is a very important 'outlet' to outwash to quite an extent, pressing air between it and the endplate.

Then we have the cascades:

Again Mercedes profiled their cascades to accentuate outwash, evident by the turning vane cascade and by bending the endplate the cascade.

Again different philosophy here at red bull. They are producing more downforce and are more about upwashing their airflow rather then forcefully bending it outwards.

Finally we have endplate and apendages:
http://u.cubeupload.com/turbof1/MercedesEndplate.jpg
A continuous endplate which curls quite heavy at the back, designed to outwash and upwash the airflow around the tyre. Creates vortices at its tips. The outside strake also generates a vortex which enhances the vortices upstream. The inside strake aids in upwashing the airflow along with creating a vortex on its own.
http://u.cubeupload.com/turbof1/RedBullEndplate.jpg
Red Bull on the other hand does not have a continuous plate. Due the wing elements being so close to the footplate, red bull needed to make a slot to get sufficient air inbetween the elements to prevent stalling. The endplate curves a bit at the back, but not as much as the Mercedes on does. One has to note that Red Bull simply has not the room to do so because of the endplate being so much closer to the footplate edge. It's winglets on the inside have almost no AoA, and are there to guide the airflow towards the upper element strake, which helps outwashing the airflow.

As you can see, there's not a single part on both wings that have the same approach. Red Bull's and Mercedes' wings are 2 completely different approaches, with the rest of the field picking solution between the 2. Red Bull did this last year too btw; just like Mercedes they only finetuned what they got and did not introduce anything really new.

The previous update, the one in Australia, did not made any particular change towards, as people would love to see it, Mercedes. This update did, however: the assessment of the wing moving towards Mercedes is however politically incorrect. The older Mercedes wing -the new one is for now a category on its own- was born amid other 2014 wings having all started with similar traits. For years now front wings have been converging towards eachother now; the new 2014 rules barely brought any change or temporary halt to it.

Red Bull was until now quite an exception, featuring the wing elements being integrated into the endplate, and having a very different upwash/outwash profile then the mainstream front wing. We now know that Peter Prodromou was infact the guy behind this philosophy. We know this because this philosophy still continues at Mclaren while Red Bull now has pretty much moved away from the unique concept, converging now towards the average front wing.

With hindsight now playing a very terrible hand into this, as at the time the Australian updates never even hinted towards such a radical change, I felt the need to correct myself .

Red Bull have a new aero package that will be introduced in Barcelona, a new FW and a new short nose says Helmut. RB also has a new PU iteration that should provide 40 more horses than what they currently have.

Oh god, the ranting about the issues with the renault PU are spreading here too?

People, this topic is sanctuary for member's who aren't even in the slightest bothered with moaning about such issues. This topic is only about the technical discussion about the physical parts of the car.

If your post got removed, you know why... .

[djos]

Since when is the PU not a physical part of the car?

[Thunder]

The Renault PU has it's own Thread. Better to discuss it there.

Aside from it having it's own topic, Like Thunders said, you didn't exactly readed my message through:

This topic is only about the technical discussion about the physical parts of the car

The key lies in the word technical. Moaning and complaining are not exactly technical debates, now are they? If you'd point to a specific part of the PU, and said "that part has this, this or that issue", it would have been passable atleast. Instead it was the same garbage from the team thread.

Sorry i didn't realise it had its own topic.

If it's about ranting and moaning -> no. Just keep it for yourself then. I didn't create that Renault PU thread for that purpose.

Is this healthy?

I noticed that too, made me cringe. No wonder they're having Brake Problems.

They are moving from an upwash design to an outwash design. I wouldn't be surprised if the cascades change to a Merc style soon. To me the change makes a lot of sense. An upwash design is fine back then when the front wings were the full width of the tyres, but since reduction in width last year, the flow off the end of the wing should see much higher blockage from the front tyres, which makes an outwash design a more logical design choice for me.

If you watched Scarbs latest video where he talks about Merc's newest front wing, he mentions the long lead times to design and make one, making me think this change wasn't a recent decision. It might be they revaluated their front wing philosophy after PP left and realised maybe Vettel's struggles with the car is partially contributed by the rear end ingesting dirty air off the front wheel wake which is insufficiently controlled by an upwash design. Else, I don't see a reason why they would totally switch philosophies if the upwash design is sufficient.

If it was a PP thing surely the McL design would reflect that, no? (Haven't paid attention to aero designs lately, I don't know if the McL is or isn't like that)
