Can you incorporate a cape in the front wing?

No - it wouldn't help anyway without Y250 downwash.

How's the rules on chord twist of the elements? Could we see part of the wing moving air down to the venturi while another part generates upwash?

The rules are very limiting on how much the shape of each element can vary from end to end. It’s almost as though they have thought of this!!

As Stu said yeah, very restricting. Most of the downwash will be from front suspension which is also heavily restricted.

Indy Car is a much better viewing / racing product than F1, they’re just a little slower, heavier, and less downforce.

I hate that it’s being used as a negative because it’s a fun series to follow.

If you can follow it. It's f-ing exclusive now that it cannot be watched anywhere... And I'm not about torture myself with illegal internet streams, especially from America with 8 minutes of advertisement for every five minutes of racing. I did it once, it was enough. Same damn Silverado commercial 10 times in a single hour.

ESPN is terrible..

I'm lucky... Here we don't see the ads while pictures continue but the commentator's voices goes away...

Here in Ass’traya we’ve been forced to give that scumbag Murdoch money for access to F1 via his Kayo streaming service. Or pay extortionate prices for his steaming PoS Foxtel cable service.

The only upside is no commercials during the race and the Sky commentary team. Despite their extreme British bias, they are generally decent.

I was thinking the same thing the other day. It's not possible to have lifting wings because of this rule. The best you could do is have NACA 4-digit style neutral wing sections with a lot of nose up incidence.

3.9 f. Assessing each closed section independently, the part of any closed section visible when viewed from below may contain no concave radius of curvature.

That doesn't make sense as the cape was not used to route the y250, but rather provide clean air behind the bargeboards to the leading edge of the floor. The y250 ran along the bargeboards.

The cape had a big influence over the y250 position and intensity.

By stopping the y250 from migrating inboard, but it also interfered with y250 formation if it was too far forward. The stagnation pressure at the cape inlet also steered the y250 as a high pressure trough steers hurricanes. But I'm drawing a blank as to what was meant by downwash from the y250. Help me out here. How would no y250 stop a cape from helping to channel front wing airflow to the floor a bit more effectively? Other than it being illegal per regulations ofc.

The downwashing side of the Y250 hits the cape edge at almost 90 degrees - most importantly the cape vortex can only exist if the Y250 provides the downwash. The goal here is to NOT make the cape provide clean air but rather lots of mixing. Notice that the cape is counter rotating to the Y250 BUT co-rotating to the barge board floor slots and the floor leading edge vortex generators. The whole aim of these cars is to spin the air one way under the floor to get more mixing. The cape is the first, then O-nose fences (where applicable) then barge board slots, then floor leading edge vortex generators and finally diffuser strakes.

So the y250 downwash raises the pressure on the top surface of the cape, creating the pressure differential between the upper and lower surface to make the CC cape vortex?

The nose on the new cars and the front wing connecting to it can create a CC vortex, the nose cone acting like an endplate for the inboard wing elements.

Somehow the neutral section introduced by FIA in 2009 now seems to be the most important part of the aerodynamics some fans

I don't know, but did anybody else spot the front Pull rod suspension in the AT-video, posted a few days ago on Twitter?
I know it's just a render, but could this be a new 2022-trend? Since 2014 I only think Ferrari and McLaren had front pull rod suspension.


The showcars obviously didn't have pull but push rod:
