Mercedes GP MGP W01

I think Brawn feels he would be better utilized if he spent more time at the factory. He has sort of hinted at this. I expect him to step back into the technical head role. I expect Schumacher in time to fill the CEO role. Maybe Jock Clear will step up as team head?

As for the F-Duct... I don't know how much there would be to gain with a passive system. It would be very hard (I'm guessing) to stall the wing at a specific speed and then quickly reattach the flow when the speed drops. I think teams would have gone this route if it was easy to do. You get rid of all of the ducting and extra mass on the car needed for such a system. A passive system would more than likely acutate much later on the straights than you would want it to because you wouldn't want the thing stalling on fast sweeping turns either. Probably the main reason why teams go with a cockpit actuated system. They can actuate it as soon as they are chugging down the straights.

The Merc system is driver actuated, like all of the other teams. The main difference between the different teams' systems is where on the rear wing it blows.

If indeed that MGP system was an F-Duct that could be legal next year, I would do all to convince the competition that the system is active as well. I have no clue about how far other teams have looked into this kind of F-Duct, but it could be an advantage for next season to keep pretending it is an active F-Duct.

+1

Although I do believe it be an "activated" F-duct. However, I'am only going on hearsay for my belief.
But if you actually look at the system, the rear endplates are too thin to support it, furthermore there is no tubing from the new exhaust blown diffuser. There would be some tell tale signs that the air is being channeled in such a convoluted fashion.

And as Mandrake' has said, if the device is passive, as the initial rumours before it appeared were, then Brawn has indeed somthing of a coup.
In addition, there have been a few changes made to it....

The first solution blew the top wing, the second solution blows the bottom wing. Same change Mclaren made.

[JohnsonsEvilTwin]

But the inlets have no mechanical connection...so how could it be "operated".

McLaren did run a blown wing in Monaco last year similar to Mercedes this year.

I assume it was passive. But I remember Whitmarsh saying at the beginning of this year that they had the blown wing once last year in Monaco and was surprised nobody picked up on it and used it this year

The more I look the more I'1m inclined to think its passive.
Brundle walking up the grid reffering to things is hearsay and swayed my thoughts...but this is pretty indisputably passive on the Macca...

[Owen.C93]

Yep McLaren's Monaco solution last year was "un-switched"

And the solutions look identical.

The Mercedes F-Duct is NOT passive.

The ducts run through the rear wing end plate. Theres has been as least one race where Jock Clear tells Rosberg over the radio not to forget to use his F-Duct. Martin Brundle has confirmed during a grid walk how the tubing runs from the cockpit through the floor to the end plate. Ross Brawn and drivers refer to the system as F-duct, not merely a blown wing. What more evidence do you guys need to accept that they DO have an active system?

You are correct. And what about the request from Schumacher, to have the actuation move to beside his hand, from a position where it was activated by his leg (foot or knee)

There are now strong rumours that Brawn is either stepping back, or is in fact being moved back, to a lesser role in the team. Does this mean that Daimler will be calling the shots in future?

After the qually session in one of the mid season races there is even a request listed by the FIA from MGP to be allowed to change an O ring seal in the foot operated part of the F-duct system.

[dren]

And the solutions look identical.

They do look similar.

[JohnsonsEvilTwin]

And the F-duct O-ring change was made in the second race using the F-duct. This was the "switchable" one IMO compared to the latest one which bears all the hallmarks of the one Mclaren used last year. Which Whitmarsh himself said was passive .

Edit*
Mercedes raking in the cash and ready to break its sales record. Doesnt seem like a mediocre W01 has had much impact...the board will be pleased

would it not be next to impossible to impliment a passive system with a movable rear wing?

that is coming in next year i think

I guess it's worth finding out what part will actually be moveable. If it's just the flap that will be moveable, it still might be possible to implement a passive blown wing on the main plane, as the W01 has it now?

[dren]

Ahh I forgot about the moveable rear wings next year. You could have the wing move and stall itself rather than have some blown contraption. Depends on how many times a lap you can move the wing.
