Now i guess its getting clearer and clearer
they have ducting around the sidepods and through the inside of the R W endplates it reaches the wing
is it right guys?

I think it not possible to divert air flow through such narrow and winding air pipe without cause excessive drag at the entry point.

My guess is they are just wires for sensors or possibly running a simulation device to study the effect of stalling the rear wing.

[nacho]

I wonder if their gonna make a wing that has the duct and the switch right in the middle of the wing.

[Pierce89]

Nope, isnt that where the rear wing can be adjusted?

Exactly. Besides the 'piping' goes all the way down the endplate:

I think that what you're seeing there is a pitot tube for sensing airflow somewhere, and they've chosen that snaky route up the endplate in order to reduce the disruption to the airflow as a result of the tube being taped there.

I would have thought that that tube is way to small to perform any useful blowing function, unless it's fed from a compressor of course!

agreed. Definitely wire for pitot tube or array.

[JohnsonsEvilTwin]

That is very definately a sensor cable or wire/pitot tube(what is a pitot tube?). I think this is just the rear wing device they will be testing as there appears to be no aperture firstly to capture the air, and secondly that there is no visible line for the air to reach said device.

If by some miracle it is an "air cable"... I think the Merc lads would have done a better job with the gaffer tape!

[PlatinumZealot]

Why can't it just be a wire that goes from the sensor in the wing to he ECU? that's all I think it is.

The doughnut thing on the wing, it's probably just a cover for the new hole. They might be testing the pressure inside the wing as if the F-duct was turned off...? But if it's the actual F-duct itself... then wow..

I think it's a passive system, because it looks race ready to me.
Heidfled, Schumacher and Rosberg have all said that it works.
The temporary wiring must have been for measurements.

Surely there are slots somewhere n convenient places, one in each of the flaps,with the half circular duct basically acting like a communicating vessel.
Depending on the speed of the car, changes in the pressure difference between the slots change the wing behavior. The device is tuned so that wing stall is induced at high speed.

It's not a staller. Looks like a suction for the top element. It uses a pressure balance between the suction on the bottom element to pull the flow on the top and keep it attached. So it increases down-force efficiency.

So it's a completly different approach by MGP, interesting, but I still don't really get it... How exactly is this thingy working? Pics would be nice

i think that is very true look at sauber, ferrari there tubes dont go through the cockpit so in no way their drivers leg can control the flow of the tube.
if u look at mclaren's system there is no evidence that the tube came from the snorkel its people's imagination that claim the system being an active system. i believe that the air simply came from the top of the inlet above the drivers head the 2nd hole on the engine inlet


and if it is a active system it therefore will be illegal as said on the coverage of the bahrain grand prix

[raymondu999]

It's not "active" in that the McLaren doesn't use hydraulics/valves to control it. But the knee serves as a pressure switch though. It's "driver-activated," not "mechanism-activated," and hence it's legal. Or so the FIA says.

[mike]

if the knee is moving its active.....hell even mass damper is active how is moving ur knee non-active, in this case u can say moving ur need to hit a switch is non-active

but that not really the point, there is no evidence to suggest that the snorkel feeds the hole so knee or no knee is irrelevant

True! Heidfeld confirmed in an interview just now that it's not yet controlled by the driver.

[WhiteBlue]

The new wing isn't an improvement. Nico dropped it for quali and was 0.7 s faster than Michael who used it. Lately Nico used to have one or two tenth in hand over Michael so the impression is clearly for the wing making the difference.

[marcush.]

still schumacher maintained he did work with most of the time with the new wing whereas rosberg was spending most of the time with the old one.. the question would be ,have they done their best lap times in FP1/2 with the same wing? without knowing in which configuration times where done,we are at a loss in explaining what happened.
For sure we can say before qualyfying Schumacher was not far away ,the odd 2 or 3 tenths but suddenly he lost another 3 tenths to Rosberg..constantly..
