A thread of Dr.Obbs going into what he thinks the new low downforce rear wing is doing with the cutout in the middle

[Vanja #66]

Yeah, no... G flap that close to the DRS hinge will only increase the pressure locally, which is what you want to do. This actually helps to contain the detached flow, by not allowing it to spread out.

The cutout is there to reduce drag with DRS off and it will also (likely) introduces two vortices, like a typical V-notch would do. Again, G flap on the edge there would enhance the pressure gradient needed for vortices to form.

This rear wings are funny things. Last year red bull run rounded flap ends, this year sharp like a knife. Mercedes last year a small radius endplate/wing transition, this year very big radius.

So in addition to the notch, there is also a dip in that area of the RW? Interesting, wonder what that's for

Better DRS performance (reduced drag by reducing camber)

[PlatinumZealot]

The need to go back to the downward cannon exit. I frgot what's the term Toto called it. This normal shapped engine cover is not as efficient at cooling it seems. Thats sorta could be why they had to close of the louvers after seeing the aeroloss was too high, and they overestimated how cool the night would be.

Deisgn as old as time. Teams had versions of wavy wing flaps i think back to 2010? Or even early 2000's.

Optimizing pressure distrubtion behind the flap. Lowers drag.

That's a huge blunder if by deciding wrongly to close cooling slots to gain .025s and lost .4. Either the love muscle is full of --- or somebody seriously cocked up the cooling calcs.

Funny caption. The DRS mechanism is actually different.

[nicolas]

The mechanism is not different, it is very similar.

Lewis with more downforce

[RicME85]

Thats a pedantic response
Clearly meaning the whole off the DRS mechanism and attachments. Whilst the components of the mechanism are similar/the same its clear that the rest of it is different. The swan neck mounting is different as is the pivoting section attached to the wing and actuator
