Ferrari SF-26

So serious question, if the front wing has to be changed during a race, is there a ‘bit’ which needs to be connected to allow the active aero to work? Or will it be as quick a FW change as it was under last regs? Ta

Contacts are embedded in the frame, they engage by fastening mounting bolts. Kind of like when you put back a wireless phone to charge.

That is true if the system is electrically actuated. If there was some pneumatic or hydraulic system, it would be more complicated.

Even in that case, you put the hydraulic part after the nose and electrically actuate the hydraulic piston.

They already have a standard data connection between nose and chassis, they just reuse that since it’s likely something like CAN bus that they can extend and repurpose for whatever they need.

Wouldn't you need pressure from the central hydraulic system to actuate the piston? You could use a hydraulic quick detach connector in that case.
Kind of academic though because I suspect most people went for electric motors anyway.

Or a piston that actuates from the chassis and presses into a hole on the nose. Could easily line that up.

Actually you could have just a small reservoir of oil in the nose and actuate its pump (in the nose) eletrically. In that case the connection would be easy.

You can have a screw and a small motor rotating the screw to generate pressure for example.

minor addition :
CAN (or any other automotive data protocol) bus is fine to provide enough juice to power a temp sensor or IR sensor etc, but it wont be able to power a servomotor that has to fight against aero-forces to move the flaps up/down. There definitely will be present some kind of 'power lines' as well, alongwith 'data lines' that make a male-female 'connector lock' between the nose stub and the nose when they come together.

This is one of the more plausible ones.
I would say, why not a completely mechanical linkage? The hydraulic line ends at the detachment point, in a metal rod, and in the nose there are no hydraulics, only a carbon fibre rod reaching the wing actuator.
One thing to add, is that the wing has to be moved in both direction. So you either add a spring so it jumps back up (or vice versa) or you have to make your mechanical contact to function in both direction. You can not run probably legally with the wing stuck in either position or getting loose.

There's no other way to do it but a spring, you would need 2 hydraulic circuits, or something very smart, to pull up and down with the same piping. Anyway all of these are likely electromagnetic pistons as it's easiest and most reliable.

Im looking forward to seeing the non-primordial Ferrari. They usually have lots of interesting tricks
