That is very interesting, a passive system coupled to an active system.horse wrote:This is VERY interesting!
Look how the channel travels into the main element, not the flap (top arrow).
Also notice that the original slot system (bottom arrrow) is still being used. How these systems work together is a mystery!

it's being fed by a snorkel mounted atop the left sidepodHungryHebbo wrote:Am I the only person thinking that the F-duct system on the Macca ISN'T driver activated? If Sauber have their version being fed from the sidepod, that's hardly going to have a tube going into the cockpit to be closed off now is it?!
It's going to be interesting to see if this one works though
I don't think they have a control system for it yet and this is simply the inlet for the main air line to the wing similar to the extra channel used on the snorkel of the McLaren.HungryHebbo wrote:Well yes, ok, terminology description fail on my part. What I was getting at was that the Sauber's feed duct is near enough level with the driver's head, not in front of the driver where piping can be directed past him.
Note that the 150mm slot in the main plane is still there (just under fin-pipe thing) just like on the older version of their blown wing ( -> #2)thedutchguy wrote:Slightly larger picture:
Definitely a blown rear wing. Not as smooth looking as on the McLaren though.
The bottom opening works the same way the split inbetween the wings work. It's small because of the regulations. It allows a steeper angle on the rear wing to be used.horse wrote:This is VERY interesting!

I think you may well be the only one, or def in the minority! Sauber device looks like it isnt switchable yet. It took Mclaren a lot longer probably due to getting the activation working well. I dont really understand the device if its not switchable??HungryHebbo wrote:Am I the only person thinking that the F-duct system on the Macca ISN'T driver activated?

McLaren blow the flap though, not the main element. Is there any advantage to stalling the main element rather than the flap?dren wrote:The tube blows air into a more than likely hollow bottom wing which has a slot that blows onto the backside of the wing, just like the Mclaren.
Is this a little bit of hard cheese, Giblet?Giblet wrote:Nope it's for cooling
If it isn't switchable, it should still work, but also work at lower speeds, which means they just need compensate with a steeper wing than Mclaren does. I would guess since the wings don't do very much until a certain speed, that the blown flap won't do much either until that certain speed is reached. I though the wings had a negligible effect until over 120km/h.thestig84 wrote:I think you may well be the only one, or def in the minority! Sauber device looks like it isnt switchable yet.

Dont think they will run with it in the race. Maybe just testing this weekend, still impressive how quickly they have acted.
