Mercedes F1 chief technical officer James Allison is confident that his technical team has found the root cause of the German-Anglo squad’s recent gearbox failures and can make the necessary changes to avoid its reappearance.
What will be the purpose of those 2 allen key bolts on the top of the crash structure? I assume they're to adjust something, but what?
We don't usually get shots where you can actually read the FIA stickers, but if I'm interpreting it correctly Mercedes in on its 8th (H) front wing spec.
Those aren't bolts, those are drive sockets that connect to a regular ratchet. The holes they are shown in, are probably just access holes to adjust/fasten something on the upper rear wishbone.adrianjordan wrote: ↑24 May 2017, 19:09What will be the purpose of those 2 allen key bolts on the top of the crash structure?

Hi Vanja, I don't think so - I believe that it is there to protect the Y250 and the rest of the flow between the tires from the air coming off/around the nose (remember the Ferrair F14T with its rounded nose cone? They're looking for even cleaner flow), especially in corners, where the airflow increases to one side, most likely changing the trajectory of the vortices from the front wing. The added lift from its shape can be countered with more wing up front, as well as the positive effect it will have downstream.Vanja #66 wrote: ↑24 May 2017, 19:08A question for fellow enthusiasts - would you agree that separate/isolated CFD of Merc super-ted-cape could give us an answer to its general function?
I'm very interested in this and I think it could show us a general trend even isolated (center section of the wing, nose cone and the cape). If not, I would be willing to spend a few more days after initial CFD to try and make and adequate model of its surrounding...

Are we sure they're FIA stickers? Could just be from Merc production line. I see FW 286, NOSE 182, SPEC H ...
Could be that to I guess, I just always assumed they where FIA inspection stickers. Still, assuming they started at A at the beginning of the season, that's a lot of revisions.
I think they line up with the wires that help support the rear floor by hanging off the rear crash structure. I think they use the tools to move some captive fastener to attach the wires. By leaving the tools in they probably show that they haven't been fully tightened (or they're going to be removing it again shortly).dans79 wrote: ↑24 May 2017, 19:30Those aren't bolts, those are drive sockets that connect to a regular ratchet.

It looks like it generates a vortex that is then directed by the barge boards around the side pods. Perhaps it goes under the leading edge of the floor but I think not. By lifting the leading edge the way they have, a vortex will be generated that runs along the top of the "cape" and is then pushed outwards by the raised central section. It then gets directed by the devices further back, in front of the side pods.CBeck113 wrote: ↑24 May 2017, 19:38Hi Vanja, I don't think so - I believe that it is there to protect the Y250 and the rest of the flow between the tires from the air coming off/around the nose (remember the Ferrair F14T with its rounded nose cone?

That's another good possibility as well.Just_a_fan wrote: ↑24 May 2017, 21:47I think they line up with the wires that help support the rear floor by hanging off the rear crash structure.
