Scuderia Ferrari SF71H

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

I think that the floor sealing vortices don't run along the bottom of the floor but the top edge - they don't act like a skirt hanging down. A vortex running along the underside would be sucked inwards and be ineffective. By running the the vortex along the top side, the air around the car sees a low pressure above and below the floor and do doesn't try to flow in under the floor. The various slots etc along the floor edge are designed to maintain this equality of pressure above and below the floor edge.
If you are more fortunate than others, build a larger table not a taller fence.

Yes, the barge boards are now used to further seal the entry into the floor area, to prevent dirty air from entering. All this means that most of the air that runs under the car comes from under the driver, which is air coming from different ways around the nose and ends up under the bulkhead. Every car has various turning vanes and aero parts designed to increase suction in this area, so that more air would end up in there.

Barge boards (the vertical bits) are used to suck that low pressure zone outboard, once we reach "the safe zone" (safe from dirty air), then most of it ends up under the floor since we now have big rounded leading edges creating another low pressure zone. Final destination is diffuser of course.

For a while I was surprised that teams put the splitter so low, it didn't make any sense. Until it hit me - maybe they are using it to scoop even that low air next to the ground (no boundary layer on the ground, remember ;) ) since its mostly unused up to that point, it only passes under the centre FIA FW section.
And they call it a stall. A STALL!

If the rumours are true (I think there was an article on motorsport.com italy), they are supposed to bring a slightly modified rear suspension to help deal with the shaved tyres.

Is this a new position for the camera or they are going to monitor something with it?
