Aerocynamic W- ducts

This clip is purely entertaining for aero nuts. I liked it.

Is the ducted air going to have enough energy left in it to "provide downforce" after all those twists & turns?

An awful lot of money is spent on this sort of thing to NOT be effective. I'm with you on the down force part...Maybe it is intended to alter the boundary layer in some form that I'm not smart enough to see.

It wasn't clear to me if the system is actually being used by a team. I wonder if they are trying to promote the technology to someone?

You would think that is an active F1 contender IS actually using this, they wouldn't advertize it?

Mercedes uses it. I'm sure it's boundary layer control of the airflow. That switching duct looks just like a fluidic amplifier.

It's not a rulebender, that's why they're comfortable talking about it. Ferrari was reputed to have used an aeroelastic wing that flattened out to reduce the Cl at high speed (going straight) to reduce downforce & induced drag. This was ruled verboten (variable geometry).

It looks a little bit like the blow hole system used on some sailplanes to eliminate the short bubble in the cusp of some laminar flow wings.
