Am I reading this right? So the engine cover can taper down to 250mm?west52keep64 wrote: ↑04 Feb 2022, 23:55This is by no means perfect, but I think this shows how they ended up with this strange side pod inlet:

You can see the bodywork for the inlet is within the orange triangle, this is the RV-RBW-SPOD volume.
I asked this very question over in the Ferrari F1-75 speculation thread, so thanks so much for providing this info!west52keep64 wrote: ↑04 Feb 2022, 23:55This is by no means perfect, but I think this shows how they ended up with this strange side pod inlet:

The tapering towards the front of the box is meant to encourage that angled inlet styling, no? So that's why we didn't see that styling on the Haas sidepod. The FIA are naive if they didn't think teams would totally use that as a "loophole" so to speak rather than for styling the sidepod inletwest52keep64 wrote: ↑04 Feb 2022, 23:55This is by no means perfect, but I think this shows how they ended up with this strange side pod inlet:

Makes senseJust_a_fan wrote: ↑04 Feb 2022, 16:50From that view, it makes me wonder if the idea is to use the front of the sidepod to deflect air laterally and then the shape of the rear end encourages air flow down from above the car on to the rear floor. If you can't use big bargeboards to move air laterally, using the outermost strake and the sidepod front face to do it seems like the next best idea.Blackout wrote: ↑04 Feb 2022, 16:31https://i.imgur.com/HlNHPx7.jpg
No it's just a deliberate technical choice from Haas

And Anderson said about those very forward-placed sidepod inlets that "They are quite small in open area too but they are in a very clean area for airflow"
So if I had to guess I would say:
- Haas placed the sidepod intakes in the cleanest airflow possible
---> to make them as small as possible
---> to have a lot of sidepod bodywork to play with, taking advantage of the maximum allowed volume
---> they shaped that bodywork like an outwashy wing, similar to the floor stakes
---> in order to create a high pressure zone in that area of the sidepods (the green one)
---> to encourage air to flow in lower pressure zones: the undercut and the ramp behind the sidepods, the inlet, and the siedpod sides

Not quite, that's the plank you are seeing. I used the underside view of the volumes because the sidepod volume was much clearer on this view.godlameroso wrote: ↑05 Feb 2022, 04:17Am I reading this right?

Yes it appears so, and if you imagine the Haas inlets extended wider, they would have to be tapered back giving that styling seen in the show car. I imagine teams actually don't want the swept back outlets, possibly because they aren't a great solution aerodynamically. If teams want more traditional inlets they have one of two options:wowgr8 wrote: ↑05 Feb 2022, 06:37The tapering towards the front of the box is meant to encourage that angled inlet styling, no?

It looks so odd having the inlets that far forward ahead of the driver
Almost!jh199 wrote: ↑06 Feb 2022, 02:03Can someone clarify what y'all are talking about when you say the sidepod shape will push the front tire wake outboard? I don't see how this would work. The sidepods are wide, yes, but they're still lower than the top of the tires (allowing some tire wake to flow into the void left behind the sidepod) and still feature a pretty substantial undercut. To me, this would mean that the clean air wraps around the top and bottom of the sidepods, not really creating a wall of air to keep the front tire wake away.
In the photos below, I would expect the air from the centerline to wrap over and around the sidepods (blue), the adjacent air to wrap down the sidepod and move toward the floor (green), some air would go straight into the sidepod (yellow), and then the lower air would go down and around the sidepods or under the floor (orange). I don't see how air would travel around the outermost section of the sidepod to push the tire wake outboard. Further, the massive void left behind the sidepods should then bring some of the tire wake toward the rear wing. Right?

Wouldn't the 'side-wing' only control the turbulence near the floor? Leaving the majority of the upper front tire wake to interfere with the rear wing as it's drawn toward the body? And when you say rear wheel 'deflectors', are those located on the inside of the rear tires?Stu wrote: ↑06 Feb 2022, 09:12Almost!jh199 wrote: ↑06 Feb 2022, 02:03Can someone clarify what y'all are talking about when you say the sidepod shape will push the front tire wake outboard?

From CFD plots that I have seen (on this forum) of how the front tyre wake behaves with the new regs the tyre wake will be drawn into the undercut area on the Haas.
If it works how I think it could/should the small ‘side-wing’ that the regs allow along the floor edge will then re-energise that flow into a vortex along the floor edge which then flows to the rear of the car exiting roughly where the rear wheel ‘deflectors’ are located.
