Mercedes GP MGP W01

the effect you talking about, wouldnt the tabs to the side of the nose help to achieve this better?

What i can think of is that these tabs shed a small vortex blocking an line off moving upwards thus increasing the function of the nose shape.

I believe so too.
This concept is pretty radical, i guess if the W01 sticks with it throughout the season, then it works well for them.

biggles22, this is completely true, that's the basis behind the concept, and the comment by someone about increasing the speed of air along the front wing. One this you must bear in mind is, relying too much on the wings for downforce in not desirable, especially the front wing. If you can achieve the same number but transfer the downforce to the body, it's a much better result.

Most people and a large portion of F1 teams only consider straight line aero, the car is rarely in this condition so yaw and cross-wind should be more biased in terms of results and what the design goals are, yet is rearly crosses the minds of most critics.

The point of where the air would be sped up over the wing would be the middle where it is flat creating no downforce anyway. I think that the sped up air over the flat part of the wing would aid the diffuser by speeding up the air diverted to it and not have anything to due with generating downforce on the front wing. I do agree with the fact that downforce on the body is helpful but I am sure the cars are designed to produce max down force and least drag no matter how they get it.

Well lets see what today holds/

Michael is already quick today and there are updates to the car.
No pics yet so not sure if they've sorted the mass distribution or if there new aero parts.

this is a hell lof of a diffuser!!!

this is a hell lof of a diffuser!!!

Not really, the McL diffuser fills the gap to the bridge wing, and nearly full width too.

Size isn't everything, it is more important to get the supply air flow under the floor working properly.

It is still the 2009 Brawn version. See page 6.

[Raptor22]

so no new diffusor yet.
must be the weight distribution they were working on then.

im really disappointed with this, looks like theyve developed the car around the same front-wing as last year. A part can always be better. But seems like mercedes has accepted to use this frontwing as baseline. I can live with mercedes not having a new diff. yet. But the frontwing is normally the part that determines the rest of the car. So i quess its safe to assume that this frontwing will stay. Doesnt look very ambitious to me. But i hope im wrong

Don't fix what ain't broken is a old golden rule... Or maybe they'll have a new aero package in Barcelona, don't fret just yet..

Yup, they will most likely use the Barcelona test to use the totally new aero parts. Because if you haven't noticed, thus far teams have only done mechanical upgrades and have outspokenly talked of waiting until the last test to test significant aero parts.

Most of that is completely wrong, and the FIA controlled section of the front wing is not flat. I won't go in to more detail.

Also, you can't even begin to use those images someone's interpretation to try and figure out anything, it's such a dangerous/worrying fact that CFD and FEA tools are accesible to a lot of people these days.
You also seem to have realized that the expansion under the nose in a diffusive environment doesn't serve to change the pressure and velocities the same as a closed pipe, hence my reason for mentioning the closed section pipe in a previous post.

Yes the F1 controlled section of the wing is a symmetrical profile, in drawing 7 of the regulations. It can still create down force, if angled. If not there could be some ground effect too.

Concerning the part in bold:
On the contrary, . If it weren't for that, everyone here would have to hold to your/my opinions instead of making their own first hand judgment. Not saying that all assumptions drawn by posters are correct, but at least each person can see for them self.

There is no black and white between expansion in an external flow or pipe flow; the boundary conditions are what matters most. Then there are also considerations such as work done by the fluid and heat transfer etc.
I think the problem is the word "expansion", people think the word expansion is associated with of a drop in density or pressure.
Without that little example most would have the wrong idea concerning diffusers.

Here is an example by USF1, similar thing here under the nose, just less pronounced because of a more gradual underside.

Mercedes must win to stay in F1 - Zetsche

This is a serious target. 2010 could be a make or breake season for the new team. If they cannot win with Schumi he will go away and they may loose the Parent company.
