Mercedes AMG F1 W03

I'm pretty convinced the flow goes rear to front.
As mentioned before, the holes in the end plate are in a position of very high pressure (where you would normally see vortices streaming off the wing in humid conditions).

The scale is hard to read in this image, but it is 0.125 PSI just in front of the flap or secondary element. Is that enough pressure to get the flow to the FW slots? What is the pressure reading going to look like if the flap is open?

Also note how the pressure is NOT 'piling up' out at the end plates as is the common belief by many on this forum.

drag reduction looses downforce which creates a loss of tyre heat. This needs to be compensated for with a mechanical set up that works the tyre harder.They can't really do this because DRS is used over a very short section of a circuit so their set up must still work over the whole lap. But if they loose heat while DRS is enabled then they are at a disadvantage exiting slow corners. We don't really see this. What we see is a general inability to keep the tyres within their operating window which tells me they have erred to far on the side of caution.

This is a weak theory:

1) We have no idea of the nature of the tire problem.

2) The FWFD is not producing very much downforce/drag reduction. Nor do we know if changes of downforce on the straights have much effect on tire temps. This has never been discussed in regard to the DSR on or off this forum before since it was introduced.

EBD worth 2 seconds?

Indeed. Tombazis said the ballpark for performance gain with ebd in 2011 was 2sec in a recent interview

Good gief! I stand corrected. Develop away fellas, my first consignement of midnight oil is already on the way...

I wonder, why you guys still think about W03 as speed killer, ultra qualifying performer?
Look at the facts.
In Sepang qualification first 5 places were in 0.2s and it was shared between 4 different teams including MGP (MCL, MGP, RBR, Lotus)!

If you see speed trap values, and best speed at particular sectors there is no supremacy of W03 at all. Yes W03 is quick, but it's far from F-duct time where MCL had few more km/h speed advantage.

Yes W-duct is innovative but some teams obtain similar results without this system.

While its true that Mclaren are clearly faster and the rest of the pack were separated by a few tenths at most MGP has performed well at both races in qualifying. If true to form there is no reason for them to not repeat the performance.

Unless ofcourse the car is set up more for race pace and not qualifying.

Ebds are still important. Anyway you can get more rear df, means you can have more overall df. And the rb ebd was worth more than .8 I would say closer to 2 seconds so 25% is still .5 huge in f1 that's 10th to 1st at some races

THe effect of the EBD is GREATLY reduced this year. Have you seen how a Renault with no EBD is much faster than the ReBull in Qualifying? The same for the MErcs.

Great how you come to those conclusions, but how do you know that?

Drag System Reduction, really?

The context of the statement was that rear tire cooling had never been discussed in relation to DSR usage. The is first time I have heard of such an issue. Do you have any other info?

I am working on some numbers but I could us something data on the FW.

Lycoming suggested using the FW test weight, but how does it translate to wing load across the surface of the wing? I need surface loads to make a rough assignment of downforce for the wing elements.

Assuming a simple single element FW, does the aero downforce require to bend the wing match the weight placed in the test location, that would also bend the wing an equal amount? Seems like the aero downforce number could be much larger.

Anyone of a logical way of calculating this relationship?

More like; "Did I dress like that when I was Nico's age...?"

Ooops...off topic, I think MS is quite happy with the W03?

Hi guys.. my best pics of the car last time out in Sepang.. the cars looked awesome in that much rain..

[Dragonfly]

Do you have a photo with the car not so zoomed? It's interesting to see the water sprays around it.

I am not trying any discussion here, I am just correcting you. It isn't DSR it is DRS
