#BritishGP spec deep dive:
#F1 #TechTalk
The updated floor, in particular the floor edge, with a wavy edged flap, mid flap and a simpler treatment ahead of the rear wheel
#F1 #TechTalk
Another team to copy the Aston Martin bib wing. Curved floor fences, note the change in height of the tunnel roof inbetween them.
#F1 #TechTalk
Initially contentious mirrors on the sidepod wing. Updated twice with a larger side mounting and vane hanging below the pod wing.
#F1 #TechTalk
Inner brake duct detail and @BremboBrakes .
#F1 #TechTalk
Front wing updated for Silverstone. The endplate strake was lowered, the old position visible in the carbon weave above it. A cost saving over a newly manufactured endplate.
#F1 #TechTalk
Bib is supported by a stay and not the spring/damper seen on rival cars.
#F1 #TechTalk
Merc powertrain and note the insulation around the fuel tank.

First up in #BritishGP spec deep dives.
Aston Martin AMR22:
#F1 #TechTalk
Brakes and ducts, missing the discs in each case, but usefully shows the hub where desc/bell mount to its splines
#F1 #TechTalk
The AMR22 still runs the highest nose tip/wing. RBR inspired floor fences and mirror housings.
Stripes on the wheel cover help identify the nut at pitstops.

All #F1 teams run an air speed (pitot) sensor. It measures air speed from the pressure differential between two ports in the tip.
Some can also detect direction (yaw).
Air speed is important as it's what the aero works with, as its a combination of road speed and speed.
#TechTalk
As they're delicate instruments, they'll often have covers over them in the pits, McLaren's is shown here.

Red Bull like most teams 3D print theirs from metal

A break down of modern #F1 roll structure design...
Typically we think of roll hoops as a four legged 'hoop'. This creates mounts that are wide spaced, but relatively small. Creating points of high stress in an accident, where its bobded/bolted to the tub.

The blade format is quite different. Having a narrower closed structure, that widens at the base. Although the base mounting is narrower, there's a large contact point where its bonded to the monocoque to spread the load.
📷 @MetalAMMag Sauber
Although a conventional 'hoop' can also have a pointed shape and narrow mounting base. Similar to the blade concept and having similar structural properties.

Porpoising is an issue on most 2022 #F1 cars.
Red Bull have found their solution in a very clever & legal suspension innovation. So they can now run super close to the track.
With gas springs and inerters banned, they've exploited a non-newtonian fluid filled damper.

Thread:-
Everyone knows from home science experiments that non newtonian fluids are liquid, but become semi solid when a large force is applied to them. Like the Corn starch on a speaker experiment, even custard is a NNF!
I spoke to RBRs ex-Honda suspension engineer, Kesonyu-san about the system. The NNF filled damper does not affect normal suspension movement, but when the car starts to porpoise its non newtonian properties resist the bouncing. 'Porpoising Intervention Engineering' he calls it !

So we have now seen the @MercedesAMGF1 W13 #F1 Bahrain spec.
The extreme sloped sidepods are the key feature, that allow the aero to work despite their small size.
From ahead the jelly mould sidepods, do have inlets and side radiators.
To create the shape the side impact spars are detached from the sidepod and have their own shroud shared with the mirror mount.
Inside the radiators are repositioned slightly, but still in in an apparent conventional position. Also there's the usual coolers above the gearbox fed by the roll hoop.
Hot air exits through louvers and the high coke bottle exit.

Porpoising. The cars can be seen to bounce up and down at speed.
This isn't new and not only related to big underfloor tunnels.
The car gets its downforce from the wings and underfloor. The ride at low speeds gives no problems.
#F1 Image
As speed increases the downforce increases too. This compresses the tyres and suspension.
As the underfloor gets closer to the ground, it works even better creating even more downforce
(this is ground effect).
Ride height continues to reduce with the aero load Image
This reaches a critical stage, where the ride height is too low and the airflow in the underfloor stalls.
This suddenly reduces downforce, the reduction in load uncompresses the tyre/suspension, lifting the car back up to a higher ride height Image
