McLaren MP4-29 Mercedes

[slimjim8201]

If someone wants to mock up a CAD model of the rear suspension, lower "beam wing" and diffuser, I'd be more than happy to run a few CFD analyses. I could try my hand at the model, but I figured someone here has already begun.

[slimjim8201]

Regarding my last post, a CAD model would be nice, but a detailed drawing would be great as well. Perhaps Craig or one of the other members would be able to supply a side cross-sectional view cutting through the suspension members and diffuser. I'm not looking for the entire car, but just a localized cross section. Digitizing a detailed drawing may be easier than mocking up a CAD model.

Interesting the way the monkey seat connectors are little "rainbow" winglets - I wonder if they are adjustable...

[H2H]

I was thinking about that too. Dragonfly suspension is fitting better.

Add another vote for the Dragonfly.

Me too. Dragonfly fits perfectly and it makes a lot of sense to have a specific name for a specific design.

Seems that here and elsewhere, there is some confusion about what is what on the suspension. I've color coded the photos below to try to make it clearer.

Red = Upper Wishbone
Blue = Lower Wishbone
Green = Track Rod (Tie Rod)
Yellow = Pull Rod



The same from the rear - the Lower Front Wishbone and Pull Rod aren't visible in the photo...


In this one I've numbered the members:

1 = Upper Front Wishbone
2 = Upper Rear Wishbone
3 = Lower Front Wishbone
4 = Lower Rear Wishbone
5 = Track Rod (Tie Rod)
6 = Pull Rod

Hope that helps make it clearer to everyone.

Are rear legs two pieces (green and blue in your illustration) one molded piece or two joined is in question. Seems to be a hinge or joint of some type @ angle change.

[forty-two]

No separation like last year's Ferrari.

Sorry if this is a stupid question which has already been covered, but where's the starter motor hole on this car? Is that somewhere else entirely on the 2014 formula cars, or does the MGU now serve this function?

It does look like a joint, doesn't it? I suspect that it's a strain gauge taped on, though.

Clever without question tho

do they have that silverish box on the rear brake ducts/winglets in order to hide what is going on at the attachment points? (whats the proper term for those?)

It's hard to say whether the upper wishbone is made up of 2 parts, we need to see the end connecting to the upright. It could be a 3 armed wishbone.

Yea, I think you are right. Oddly, when I first saw the car in the initial presentation pictures (in the McLaren building) I thought I saw a weird 7th link. However, after looking at many pics of the rear suspension, I can only see the 6 links you mention. The dark jumble back there seems to easily confuse the quick impression. A minor note- I think the lower wishbone is probably a pair of independent links rather than a wishbone, but this is irrelevant to your count of 6, and irrelevant to the car's legality.

[Pup]

Yes, you're probably right about the rear lower link. They've had to do something tricky to get it mounted so far back - it could be that it's mounted onto the brake box; i.e, the inside wall of the brake box is the upright. I guess they needed to get it so far back to satisfy the straight-line rule.

This year it is covered by a flap in all cars. If you look closely at the pic, you can see it in the middle of the lower central zone of diffuser.
