Mercedes GP W02

Does anyone know how they actuate the flap? as the flap is actuated through both wing endplates the mechanism must be quite elaborate or you need two actuators...
if those two get out of synch for reasons of vibration or twist you are in for trouble ...Mercedes the one Team who managed to create a system that can get stuck in the open position repeatedly.This was explicitly to be avoided,right?
engineering is wonderful and teaching you all sorts of things.

I'd be releasing my finger from the DRS button a second before normal to make sure the air flow has re-attached properly so I wouldn't overshoot the braking zone after I've just passed someone. I assume it's still an aero problem as opposed an electro mechanical one.

[marcush.]

well maybe Schu is so old that his crippled fingers will not release from a button once pressed for several minutes...
seriously we saw Schumachers and Rosbergs flap not returning to normal position in one of the qualifyings...so there is some car problem.

This time it really is a mechanical issue apparently, with the wing not closing properly on braking, as Brawn said it showed in the telemetry. He also used the word "malfunctioned" rather than "stalled" which suggests a mechanical or electrical problem rather than an aerodynamic one.

The wing mechanism is hydraulic, so it would be fairly easy to have two actuators acting simultaneously. All you would need for that is one hydraulic circuit with one master cylinder and one command, splitting into two pipes going to the actuators. The issue is probably elsewhere, either from the mechanism getting blocked by something (debris, rubber marble, ...) or maybe the electric pump for the hydraulics pressure. Could just be the pressure sensor in there acting up. Or an electric fault in the command.

The problem is not with releasing the button. All the DRSs on the cars work the same way: press the button once to open, then close automatically when the brake pedal is pressed. It's all going through the ECU to make sure that the wing is not open when it's not allowed to be. There's definitely a glitch in the system somewhere.

there isn't a DRS button. It disengages when he breaks, are you suggesting Michael breaks a second earlier?

[volarchico]

If you watched qualy, there is a DRS button which was spoken about during the BBC feed. It had to be held down to activate the DRS and released to deactivate. Maybe during the race they operate it differently since it can only be open in one part, but during qualy it has a press-and-hold button.

Doesn't Mercedes have a pedal to activate its rear wing?

'According to a report from Germany's Auto Motor und Sport, the Mercedes W02s of Michael Schumacher and Nico Rosberg will feature an additional foot pedal to activate the adjustable rear wing, and will be located to the left of the brake pedal.'

Rosberg's onboard didn't show him holding any button on the straight, except when he used kers

[dren]

Yeah, the button is for KERS, the pedal for DRS. DRS deactivates when the brakes are pressed. There shouldn't be as many issues for Schumacher tomorrow since the DRS isn't used much in the race. He can get his usual 3~4 car jump at the start and fight it out with the Torro Rossos and Ferraris hopefully.

Im heartened by the teams showing this weekend so far. The car has some real pace, but I await to see if the tyres will last in race trim.

Seems cooler ambient tempratures allow the short wheel base design, with its tightly packaged cooling, to do as intended.
Brawn has said they have solutions so as not to compromise performance again. I wonder what compromises are needed that makes them that slow?

Either way, I just hope we have a series of cool races

Engine mapping and or cooling vane exits?

[volarchico]

Looks like either my poor memory, or BBC announcers getting it wrong. They definitely commented on one of the teams having to hold a button for DRS, but I guess it wasn't Mercedes!

yea, i think tyre strategy can help him greatly if they get it right
he has the choice of starting on hards, can help him fight struggling cars on softs

Brawn:" We will get a new one (rearwing) for Istanbul and it will eliminate the problem".

"One of our priorities for the next races will be introducing a new cooling solution".

I believe things are looking up for Mercedes. Fingers crossed.

that would be STR

[Byronrhys]

I just hope they don't get left behind trying to eliminate their problems, they have a good base, now they have to build on it.

The car still lacks consistency. It's definitely ok when it's in a certain range. Let's see what parts of the race tomorrow they're strong at.
