I find it interesting that Williams is running their Spa wing. Also; would it not be more efficient to actually use the McLaren/Ferrari's old style "blade" actuator rather than a "pulling" actuator as that Ferrari has? I would think it would just add that little bit of extra efficiency to the rear wing; giving more downforce for just that extra half tenth.

Suaber seems to have the less cambered sections/almost flat-symmetrical as I wrote in the race thread.
Interesting that both FI and STR go for some textbook solution to decrease induced drag, by lowering the chord (FI) or the incidence (STR) at the tips.

FI wing looks particularly refined: notice the actuator is thinner at the root, to disturb the wing less.

Curious to see what RBR, McL and Merc come out with.

I remember teams also used to work on their front wings for Monza back in the pre-09 days. I wonder why that has stopped now.

fun thread. nice to see all the special wings in one place.

Leave aside qualy strategy. For the race--
If you're a front-runner who will always be catching up to slower cars and passing them then you will use DRS often, so running a larger wing with more DRS effect would make sense. If you are a backmarker who never catches up to anyone then you will almost never use DRS, so the optimum wing would be smaller (with less DRS effect).

Red Bull and Merc were added.

Williams will test the Spa-spec against a Monza-spec rearwing on Friday. Button says that their rearwings will be much larger than the rearwings of the other teams...

we will see..

I wonder why no team runs a wing that starts at the same height as normal but finishes lower than normal. I thought if a wing is closer to the ground it is more efficient??? HRT had something similar for a while, Canada maybe?

Also why the teams not have DRS actuators in the endplates rather than in the middle in a fin. Endplate would give less drag surely.

And how would long chord DRS flap be at this lower AoA compared to a shorter flap.

Last year it was maybe but now it is not. You cutting the flap short but the DRS is still at the top of the end plate, so you have less DRS effect for same efficiency.

You will get fatter end plates, give less chance of using slits in the end plate also making the end plates much heavier. You give away a tad of wing area and the cnetral part probasbly has some positive effect under yaw.

Would give you an nose up DRS flap

Is that two different rear wings for Williams? One is the cambered bucket shape and the kne after that is "flat"

Why?!?

[Richard]

The idea is that the U pods give less drag, so they can carry more wing than other teams.

[xpensive]

Perhaps they've got the MGP engine-spec from MHPE for this weekend?

[raymondu999]

Anyone have shots of McLaren's rear wing? I hear it's noticeably steeper than the Red Bull

Referring to wesley's post from earlier...

Last year it was maybe but now it is not. You cutting the flap short but the DRS is still at the top of the end plate, so you have less DRS effect for same efficiency.

Could not the hinge be lower down as well since it has to be on (ish) the trailing edge and that is what we are moving? Therefore same drag reduction effect.

You will get fatter end plates, give less chance of using slits in the end plate also making the end plates much heavier. You give away a tad of wing area and the cnetral part probasbly has some positive effect under yaw.

DRS bits have to go somewhere anyway so the extra thickness/weight should not an issue. If you use a small flap its not in the way of slots and some teams aren't running them anyway. Surely if they wanted better yaw performance they would stick a great big fin in there as allowed under the rules although some teams (FI) seem to not want that so they separated DRS from wing as much as possible.

Would give you an nose up DRS flap

Can't you just reduce the angle it opens to?

Updated. The Williams Monza-spec (not Spa-spec) looks as big as the McLarens...
