McLaren MP4-26 Mercedes

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

uprights? Do you mean the swan neck support in the middle, or the endplates of the rear wing?

Sorry, endplates. English is not my first language so I still get technical terms mixed up sometimes...

I didn't mean to put the spotlight on your English mastery mate. Apologies if I offended you. Just got slightly confused, that's all. Cheers :wink:

Wrong. That is the incorrect comparitor. This is correct:

Image

Looks a bit assymetrical now, doesn't it? :wtf:

Edit: Oops, quoted the wrong text.

I can see why people are saying it's asymmetrical, but the inside edge of the upper part of the front wing (where the yellow line on the left is marking) is a curved edge, whereas the other side (the second yellow line) is a straight edge. This gives the impression that one side is raised and the other is not.

A top down images of the MP4-26 front wing would paint a better picture.

Before anyone says it, yes I was fooled at first too.

Guess it was asymmetrical when they did the press photos to then....
Or might it be an illusion that occurs when the angle of the photo makes the nose hide the inner part of upper flap........

NO, I think the wing is very symmetrical. You odd to consider the angles from which the picture is taken. If you had a picture from the opposite side you would say the same.
The picture is what at an inclination of appr. 30 deg from top and around 45 deg to the main axis. All parts of course have there own shapes, radii and given the perspective it would appear as it looks, but still be perfectly symmetrical.
Optical illusion!!

Again, probably optical illusion. If you find a picture that is spot on from top and right up from the front, without any angle you will see that everything is symmetrical.

Here, I've tried to show what I've explained above.

It's not an optical illusion as such, it's just that due to the 2D nature of the image and the angle of the photo, reference points for 3D perspective are lost or obscured.
Yer.

Dude, I said it _looks_ asymmetrical, but is in fact symmetrical. Read it again :P

I guess that was what I tried to say Hangaku. So it is symmetrical.

thanks!!

What is that carbon fibre fin on top of the diffuser, just left of the crash structure ? It's tilted around 45deg to the outside, and it's assimetrical too, I can't see the same piece on the right side.... :wtf:

EDIT : Maybe the crash structure is just obscuring it on the right side ?

The other side is indeed hidden by the crash structure.

I think it's just a little foil there to guide the hot air from the cooling aperture above the gearbox to the top of the diffuser and help keep it more or less in the center of the car.

It could help the efficiency of the diffuser / beam wing coupling to some extent to have a stable and energized airflow there.

Sidenote: The symmetrical / asymmetrical debate needs to stop guys. It's pretty obvious the wing has the same angle of attack on both sides of the car.

What induces the optical illusion is that the top foil of the wing has twist, like airplane wings: it has more of an angle of attack on the outer edge, near the endplate, and flattens out as you move towards the centerline of the car.

Look at the structural design here guys. The way the diffuser and rear wing uprights are held by those thin posts, acting as splitters for the slotted extension of the uprights behind the diffuser, with the whole thing bound to the crash structure using the beam wing.

This is some beautiful coupled structural / aerodynamic engineering with impressive attention to detail.

Whether or not this L sidepod thing ends up winning races, you can't say that the Mackie Boys don't put some serious effort in. And they've got some serious skill in the details.
Yes, it is beautifully done, but beauty doesn't always win races (see, for example, Ferrari 330 P4 and Dino 206 SP).

BTW: Superman called; he used his X-ray vision and confirmed that the McL wing IS symmetrical.

Guys, it's not necessary to keep posting the same picture several times on a page. It breaks up the flow of the thread.

Just delete the image tag in the reply box and just quote the text you're replying to. Alternatively just start your reply with " @<name> " or similar so it's obvious what you're referring to.

I'm sure the Mods will be grateful too...

In that image you can see the hole under the crash structure were air passes through the starter hole. Right behind the temp sticker.

Here's another view, albeit a lightly different diffuser.
