### F1 2022 Technical Regulation

Greetings,

I was reading the technical regulations, and I didn't quite understand this specific point (3.10.1 (c))(rear wing). Can someone explain this to me, please?

It states that: Outboard of Y100, the normal to any point of the profiles surface must not subtend an angle greater than 20deg to a Y plane.

Thank you.

It means the wing profiles can’t dive or rise too steeply in a spoon like shape across the span.

So, if it's a flat wing, how does the angle of attack or the camber of the wing profiles varies with this point? Can the flap have a bigger angle of attack as usual?

The angle of attack / flap angle will be measured on a different plane - the X plane. X is front to back, Y is side to side, Z is up and down.
If you are more fortunate than others, build a larger table not a taller fence.

Let's say we are using NACA 6315 airfoil as the flap, and the angle of attack is set at 30deg, won't the angle between the normal to any point on the profile surface and the Y plane exceed 20deg?

The Y plane goes from side to side. So you're measuring the angle change as you go from one end plate to the other. No change in direction along that journey can be greater than 20 deg. If the wing is flat from endplate, through the midspan point and to the other endplate than the angle to the Y plane is zero at all points.

The angle of the surfaces measured on the X plane - that runs from front to back - isn't controlled. Hence the angle of attack and the flap angle can be greater than 20 degrees. If it wasn't this way, the wing would have to be basically a flat plate.
If you are more fortunate than others, build a larger table not a taller fence.

Right, now I understood it. And yea that's what I thought, a flat plate, that was the confusion I had. Thank you for helping

A similar wording was brought in for the front wing in 2019 so that's a good place to show how it works.

It relates to the green line below, so across the span. At the tip where the wing profiles sweep to the "cone" section the wing "subtends" at an angle of around 35-40° then where it joins the footplate it has an angle over 90° (negative from the zero axis) as you follow the line around.

To ban these tip cones the FIA said the maximum angle the wind could subtend was 15°, outboard of Y450, so wings now look like this. i.e. quite flat by comparison.

1. I think that there will be more emphasis on suspension than ever before. Maintaining an effective "seal" with the new underbody tunnels will be high on everyone's list. Added to that the 18" lower profile tyres will require more movement and compliance from the actual suspension components than the old 13" tyres with taller sidewalls. Traditionally McLaren has always excelled in this area.
2. But also traditionally, in any year with massive new aero rules, Adrian Newey cars were the best out of the chute right away. True in 1996, 1998 and 2010 after the 2009 blown diffuser was outlawed. Adrian always debuted his cars very mature and it took the rest of the grid a full year to achieve 85% aero parity.
3. And we can't rule out that some midfield team sees something in the regs that everyone else misses. Look at 2009 when Ross Brawn saw the blown diffuser and they owned the rest of the grid for the first dozen races before Newey and Vettel could give them any trouble.
4. Merc traditionally excels at tyre temp management. Supposedly the 2022 tyres can be raced more aggressively for longer. This could gather the field closer if less is to be gained via brake heat to the rims etc.
5. Because of suspension issues, I would not be surprised to see McLaren beat Mercedes on merit for 2022 before Merc catches up in 2023. I think Red Bull is the favorite to win both titles this year... unless Ferrari surprises, and it would be a huge surprise. A dark horse would be for Renault's new engine architecture to bear fruit and move them into the top four a head of Ferrari.

'09 Red Bull didn't see the DOUBLE DIFFUSER (not blown diffuser) and were behind until developing their own. The blown diffuser wasn't banned until the end of '11 going into '12 which you could also say that Red Bull got wrong after it having to be reworked to work with body work(coanda effect). I wouldn't say Newey's strong point is new rule interpretations but refinement

Hi All

Can someone help me find out max lenght on new 2022 cars? According to new regulations the must be a bit shorter but i can not confirm that?
Thank you All

IIRC there is no Max Length for the car itself... The Max Wheelbase however is 3.6m...

12 cm is huge in F1. That is why new Haas VF22 have much wider sidepods in order to have slim rear packing. I think we can expact similar solutions on other temas and cars as well.
