#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.

I've given a short delay to respect the hard working @WilliamsRacing staff.
But their excellent video on the post-brazil rebuild shows some nice details, we rarely get to see.

Some analysis into the #MV33 brake failure & fire at the #AustralianGP.
RBR said the right rear caliper was stuck on, which would have been detectable by pressure sensors.
So, it wasn't a blocked brake duct (my initial guess).

The heat from the brake being constantly on, set the brake duct on fire.
However, the brake disc did not explode when entering the pits. As the disc was still visible & intact in the pits.
The blast was probably the wheel/tyre failing releasing the air & blowing debris everywhere

So, where does the brake system split to isolate the RR caliper and what parts might be responsible?
The brake system is split front and rear.
The front shares the same pedal and tandem master cylinder with the rear, so we can exclude those parts. Image

It's been exactly 3 years since Romain Grosjean's huge accident in Bahrain.
The monocoque was on at the @F1Exhibition in Madrid this summer.
I took some time to look over the tub and noted the damage, which included elements I wasnt aware of...

Summarising the crash
The car went intact into the barriers at 197kph, at an angle on it's right hand side. This was the biggest deceleration, 67g.
The car jammed in the barrier and flicked around to the left, breaking apart in doing so, the survival cell remaining in the barrier Image
2)With the initial frontal hit to the barriers, the nose box wasnt evident on the car or track in the post crash pics.
But some of the nose is still attached to the right, but little remains on the left.
Most of the length of the nose appears to be used in absorbing the impact.

Williams are another team bringing a big update to their car.
The FW45 has had a thorough aero review, with one set of bodywork readied for #AA22 at the #CanadianGP.
#F1 #F1Tech ImageImage
The floor is the key change. Mostly the underside, but the inlet fences, floor edge and diffuser are more visible changes. The rear brake ducts are reworked accordingly.
#F1 #F1Tech ImageImage
Also the sidepods, feature new inlets and a deeper scallop to the waterslide. Directing more flow to the diffuser.

The first big update to the AMR23.
Heavily revised sidepods, floor edge and cooling outlets.
#F1 #F1Tech #CanadaGP ImageImageImageImage
The waterslide is narrowed and starts with a distinct edge. This may be to contain the rotating airflow, which marries up with the revised undercut, to create more load over the diffuser.
#F1 #F1Tech #CanadaGP ImageImage
The undercut feeds into the floor edge further back and with more more load.
The floor edge has been revised, but not in a substantially different way.
The rear tyre temperature sensor is embedded in the floor (red)

Corner entry deceleration issues for RBR persist.
#F1 cars 'brake' in several ways. There's the hydraulic brakes, hybrid braking and engine braking. All affect how the car slows & rotates into a turn. From inputs at the pedals, calculated by the ECU.
#F1Tech #AustralianGP
Simply lifting off the throttle gives engine braking. This map can be varied from the steering wheel button (EB or Torque). Altering the throttle/fuelling at that moment.
More EB (up to a point) gives stability/understeer. Less EB gives more rotation.
Confusing things more are the differential settings, that gave a similar balancing effect on corner entry.
