Red Bull RB18

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

This car is an absolute jewel!

From these pictures, I get the feeling that they are blowing the diffuser with the flank of the sidepod and the tyre squirt area.
They are basically ramming air into that tight space, almost like a nozzle effect. They should get more suction from the diffuser, but critically, they have a better pressure gradient between the front and back of the car to mitigate against choking.
Exactly! The venturi effect works by shooting a jet of air into a diffuser, the air from the jet turbulently mixes with the diffuser and effectively pushes the air out of the diffuser. In doing so, it draws in more air through the inlet, which then accelerates through the throat, which shoots into the diffuser as a jet of air, turbulently mixing and pushing the air in the diffuser out.

This is why no diffuser has perfect pressure recovery, there's always a small pressure loss. And why reducing the back pressure in the diffuser/outlet increases flow velocity, as it increases the mass flow everywhere in the pipe. Even when the flow is choked, you can further reduce the back pressure after the throat, which will result in an increase in flow velocity via Prandtl expansion fans.

Maybe?

Is it different to these ones? Looks similar:

No, it the same as in KSA.

Craig Scarborough just posted a rear suspension layout, probably similar to the RB18s. He adds that RBR reaction bar may has his own spring as it has a linear sensor mounted to it, creating a dual rate heave spring effect.

The lower element looks like a half-way solution between Bahrain and Jeddah, also the end plate has a little curve on the leading edge where the "o" in Esso is at.

Again "expert hawk eyes" saw nonexistent new parts and MSM took information on face value and spread disinformation. Somehow sounds familiar in a global sense.

There is some similarity in the upper rocker design to the Mercedes Project 1 hypercar

The horizontal spring controls heave stiffness. The diagonal spring controls corner stiffness via 2 different springs along the same shaft. Each reacting independently to the different wheel corners. Quite clever actually. There's a youtube video from Kyle explaining it.

I know that Craig is not claiming he drew the RB suspension, but I think there is still some differences in implementation to what crew has drawn. Particularly relating to the corner damper at the top, and the linkages at the spring that is at the bottom that he calls the "reaction link". I think the right side is fixed based on the pictures from the RB.

Always expected the teams to go for a conventional suspension with two vertical dampers and horizontal torsion bars pivoting on vertical rockers and a third damper, similar to this one :

Also, I'm getting confused between Craig's drawing and the actual RB rear end. The detail at the bottom looks completely different:

Completely agree, i was confused, too. I missed a third element (damper or heave spring) on top. I expected two vertical dampers and a third element(heave spring) on top.
