McLaren MP4-29 Mercedes

[Alexgtt]

The McLaren is really starting to look extremely refined already. Getting so much clean running in Jerez really put Merc, Ferrari and McLaren on the front foot. Love the detail changes. Monkey seat is beautifully made and integrated with the exhaust, crash structure, rear wing support.

Any word if Merc and Ferrari engines are running at 100% boost and ERS now? Was suggested running at 80% in Jerez.

IT's ok anyway on my twitter there is time and ma twit is previus of omnicorse article

No problem with omnicorse only personal satisfaction

That is noble of you, but to be honest also naive. And the fact that they took that image is implicating something much worse, that is omnicorse ripping off ideas here without proper credit to the original poster.

Also the "technical explaination" is incomplete (wrong?): they say the nolders are for downforce, and overlook the function of increasing cooling with the low pressure behind them

Perhaps overlooked as it was me who posted it first (2 hours earlier) and then the image was mirrored and cropped it LOL but then this isn't a war on who did what first but clearly Omnicorse shouldn't be: A) posting a Sutton Image if they don't have consent (not sure if they have a Sutton license, I'd have to check) and B) giving a crap analysis on a part that deserves a better explanation IMO

Would it be correct to assume that the huge new monkey seat is being used to redirect some of the exhaust gases to accelerate the air flow underneath the rear wing? Seeing the pic of the Sauber exhaust plume today makes me think it'd be possible and with the massive two-element monkey seat and the Zircotec heat coating underneath I think they are going for something similar to what Scarbs hypothesised the launch version of the MP4-27 was doing:

The monkey seat is most likely there to help the diffuser rather than the wing. First of all, the high pressure zone of the monkey seat intersects the low pressure zone of the rear wing, so they actually reduce each other's efficiency. Not by too much, since they're so far apart from each other, but they're hurting, not helping each other. Additionally, you don't want one wing to be using the air coming off of another wing because it's bound to be more turbulent than the free stream. It may still be possible to energize rear wing flow by redirecting the energetic exhaust gasses, but I think the monkey seat is too far rearwards relative to the rear wing to be doing much of that, which was probably the intent of the regulations.

tl;dr, I would think that it's making use of the exhaust gasses perhaps to help keep flow attached to itself, which probably aids diffuser extraction, and probably doesn't do much good for the rear wing. You'd rather aid the diffuser than the wing, it's in ground effect and works more efficiently with respect to drag.

how low does that mclaren look and how absolutely stunning
despite the weird nose, i'm inclined to feel this is one of the most beautiful f1 cars ever,
and it looks right up the mclaren phylosophy alley; low nose low COG.

I think so. McLaren are introducing a lot of air into that zone - exhaust, engine cooling, and I suspect the side pod air is being deflected up there as well by the air dam. Think of the top of the suspension as essentially the top of the diffuser - they'd want a lot of air in that zone to help couple the diffuser to the rear wing. If they can get/keep that air flowing upwards, then all the better.

The shape is nice. Clearly a departure in design philosophy. It's a mimicry of the redbull's shape in the past.
In fact it's quite exaggerated with this car, from the tip of the nose to the end of the sidepods.
Should be an interesting year hopefully if this car is back on the top.

I love it, especially the color. + it is full of ellipses.

But the monkey seat is for the RW, this has been discussed before... Sure its much larger this year prob cause of both aving the exhaust there and losing beamwing but originally it was for RW.

[Pup]

My understanding, which someone may well correct me on, is that while the interaction between the wings does reduce their individual efficiency, this is more than made up for by the added surface area of the second wing, or monkey seat in this case.

Thus, more downforce but added drag.

Really? I thought it was widely agreed upon that it was there for the benefit of the diffuser at some expense to RW performance.

Sry yeah i was in a haze this morning, i was thinkin of the dicussion bout the monkey seat in itself creating downforce and teams using it had bad rear downforce. But your correct that it should create a different pressure behind to aid diffuser etc.
