With the 2022 rule change on the horizon bargeboards will no longer be a feature of F1 cars, but what are they, how do they work, and will F1’s designers be able to replicate their function in 2022?
Does not compute for me. I would think that, if all the turbulence air is diverted upwards instead of being deposited right behind, the slip-stream would be better. A bigger, and emptier "hole".
The 2022 cars are a lot less draggy, and a lot less able to push the air out and away with the bargeboards etc. Thus they punch a much smaller hole in the air for the car behind to slipstream in.
Because if this aero works well, a 'clean' good energy air will rapidly wash in behind the car, below the dirty wake...
Regarding the Z locations, at the left, both Side Impact Structures are roughly at the minimum height, and at the right they are at the maximum).jjn9128 wrote: ↑21 Dec 2021, 09:37The way the high inlets work is by moving the side impact structure down. The X,Y,Z location of the side impact tubes are more tightly controlled in the 2022 rules than the current spec. It will be impossible.AMG.Tzan wrote: ↑21 Dec 2021, 01:41I haven't seen any renders with the 2022 cars having high radiator inlets just like every single car since 2020!
Do you think teams won't need high radiator inlets anymore because of the changed aero rules??
btw I don't think high radiator inlets will look quite nice on the 2022 cars
I'm going to change my position, the lowest the upper SIS can be is 460mm (at it's principal axis which I assume is through the centre of the mounting face) which I think is about where they are for the current cars with the high SP inlet. It could be possible to have the high SP inlet.Blackout wrote: ↑29 Dec 2021, 12:34Regarding the Z locations, at the left, both Side Impact Structures are roughly at the minimum height, and at the right they are at the maximum).
I suppose the teams will put the lower SIS as high as they can (not necessarily at the max height - it depends where they'll put the SIS in the X axis I guess) to get the biggest tunnel entries possible, but still... we should see more variety in the intake designs, like in 2017 and before. We might see triangular, horizontal and, perhaps more old school square/vertical intakes again
Dunno if intakes à la Alfa C.37 (end of season) are still possible. MP4-26ish seem to be possible with a top SIS placed at the minimum height IMO
When a F1 car runs close to another F1 car in the dirty air round a corner/straight it can loose up to 50% downforce.
Most of the aerowork in NASCAR is understanding pack dynamics, influence of the walls next to the car, side drafting, etc. I hope F1 is successful, but CFD is hard to get right (which it is in general) when you start throwing multiple vehicles. I’m holding my breath, but I won’t be surprised if it doesn’t work how they hope.Blackout wrote: ↑29 Dec 2021, 12:12Because if this aero works well, a 'clean' good energy air will rapidly wash in behind the car, below the dirty wake...

Yeah, but where does this come from? You just wrote "less drag", without any reasoning.ClarkBT11 wrote: ↑29 Dec 2021, 15:24When a F1 car runs close to another F1 car in the dirty air round a corner/straight it can loose up to 50% downforce.
Running in dirty air = Less downforce/ less drag, making the slip stream effect stronger.
Running in clean air = More downforce more drag, making the slip stream weaker.
That image only shows cars travelling in a straight line, race cars take corners too. One benefit the bargeboards had, was the nice high energy air on either flank of the car. Your image shows that as well, it also shows this is lost on the new cars, what isn't shown is the wake profile in yaw. Last gen cars gave drivers the ability to drive around the leading turbulence, to an extent. There won't be anything like that with the new cars.Blackout wrote: ↑29 Dec 2021, 12:12Because if this aero works well, a 'clean' good energy air will rapidly wash in behind the car, below the dirty wake...
