Mercedes AMG F1 W05

[bhall]

I'm just going to be a nuisance and refer to the old McLaren flexing front wing that reduced it's angle of attack at high speed for less drag/aero balance.

Then the CP was obviously behind the mounting points, which is perfectly understandable given how close the mounting points were to the leading edge of the wing.



My objection to the idea of a wing pitching forward under loading stemmed from an erroneous belief that such an action is virtually impossible. However, it is possible. But, in no way should that be taken to preclude other possibilities.

In any case, I still think the purpose of the short nose on the W05 is to help the car in transient conditions. Any forward pitch under loading is probably an unintended consequence.

While this picture proves that a pitch forward behavior would be possible, I doubt it would be the net result after adding the high pressure from the top side of the wing. That is small near the leading edge and large in the rear, where it's force points almost perpendicularly to the axis of the mounting points.

But talking of the mounting points: I was under the impression that the trend to move those as far back as possible was to allow the pitch backwards movement. If this wing where to have a pitch forward behavior and that behavior was unwanted, the solution would be as simple as moving the mounting points forward a couple of millimeters.

I am gonna guess that the wing is effectively pitch neutral, allowing for the most stable aero structures being sent to the rear with the lightest wing possible. If you look carefully at online videos of this year's Mercedes (look at the visible vertical vanes and mark a point in the screen), a cantilever like movement is there but any pitch or twist is either absent or very small.

As ___ said on the previous page, the CP is the result of all forces applied to the wing, front and back. If additional force is applied to the trailing edge, the CP will move rearward accordingly. But , it won't overcome the tendency of the wing to pitch forward until the CP is even with or behind the mounting points (or until the mounting points are somehow reinforced).

In the case of the FW31 (in the CFD and below), that's basically a moot point, because the mounting points are reasonably close to the leading edge, and thus the CP as well.



The mounting points on the W05, however, are just about as far away from the leading edge as they can possibly be. So, either the CP of the wing is pretty far back, which I sorta doubt given the proximity of the wheels, or the mounting points are strong as hell.



But, as always, I've been wrong before...

By the way, ___, if you're reading this, how should one pronounce ____?

[hollus]

Why would the mounting points be so extremely far backwards? Do people think it is something related to pitch? (either to create it or to avoid it). Or maybe the main rationale is just to give air as free a passage to the rear as possible?
Nha, this is F1, the answer is surely all of the above and a bit of a third thing as well.
Thanks for the discussion, guys.

... the pylon that mounts to the wing to the nosecone has been exploited to stretch he FIA maximum cross section to form the longest possible pylon. This forms the mounting pylon into endplates either side of the centre section of wing and along with the arched inner wing sections, help create the ideal airflow 25cm from the cars centreline (known as the Y250 axis).

I guess the farther back the mounting points are located, the farther back the pylons can function as an "endplates."

About the off-board cooling: I judge that off-board cooling belongs here as long as it used to cool the car. It's very specific tech made uniquely for the car, so it should belong here.

I moved the posts about it anyway (to the team thread) because the article was basically just marketing/partner talk without anything specific on the tech. I'll allow some imagery of their tech to be posted here, as long as it's likely to be on the off-board cooling and not cooling used in the mercedes factory.

Where did you move it?

[Blackout]

What do you mean with ''off-board'' cooling?

The little fans they put on the brakes, sidepods and cockpit.

OK. Thanks : )

Mercedes have a new package which gives them 0.6s/lap boost, but it's not sure if they will introduce all the new parts during the Spanish GP or that they will decide to test them in the post-race testing sessions.

If that's true the other team bosses will probably start crying very soon.

The sidepods, are they actually angular in some places? Or is that the paint finish?

just paint effect--it was the same in china
