Red Bull RB7 Renault

Thx guys! So jeah that i mean this hole... So Red Bull was on that area the most radical than other teams..interesting clude...btw. Nice pic

Excuse me i m not from England and i dont understand one word; what is actually "gurney" [-o< Please "help me"

A gurney is a small strip of wing that can be attached to increase the downforce level. It's generally a pretty inefficient way of gaining downforce – it carries a high drag level too for the amount of downforce it generates.

I disagree. In many cases it gives good DF with small drag penalty. Such is the case in a small sport prototype series I worked in the past. With top speeds of 220kph it didnt affect drag and the driver could feel the effect in high and mid speed corners.

[volarchico]

That is the whole point of the gurney...large amounts of downforce for small amounts of drag.

Sorry to be dense guys, but can someone tell me what's going on here?



Looks to me like an exit from a double deck diffusor, but what would be feeding it?

Also, it looks like this is only on the RH side of the car.

There's discussion on the last couple of pages, just a perforated gurney like the Torro rosso and others, it's on both sides. Previously RB had it only on the center with pretty much a small wing used for a gurney, they modified the gurneys on the outside in Monza to the perforated variety.

Understood, but could it be that this is fed by these vents at the front of the bib:


The images on the last couple of pages suggest a top vent which feeds inboard, whereas these exit vents are well outboard.

No , those are too far away. The air would stagnate in the body.

Also feeding air there is counter intuitive, as it will be slower than the air coming through the diffuser.



these hole may be for cooling the batteries.
By the way are they visible when the engine cover is on?

[Robbobnob]

Seems you can spot them in this photo.

Yes you can see daylight through them to the starter hole/slot.

Regarding the bid vent, that isn't really a vent as much as a way to direct air to floor better. I think all teams have that.

Mclaren has something similar, but it's not shaped in that way. It's basically 2 throughs that lead to the starter hole.

In this case, i suspect that these holes are pulling hot air from the lower regions of the body work.



It's interesting because the air speed in that area is very low. The purpose is not very clear.

@ringo is that your drawing? Nice!

Yeah of course it could be that reason!

[Owen.C93]

I don't think there's any hot air since that area is filled with gearbox.

It could be that inside the end plates, that little slot acts as an extra wing. Then, on the outside since there is nothing feeding it, it must be to tune the vortecies, the gap would effectively delay the interaction between the air going over and under the diffuser. In addition it would also increase the pressure slightly of the air going outside the endplates of the rear wing. Also look where it's positioned in relation to the rear wheel cascades, and the exhaust.

It's a slotted gurney. They've been mentioned quite alot this year on F1T.

[Dragonfly]

Would someone please explain in simple words what a slotted gurney is. I know more or less what a classic gurney is but see no slots on the photo, neither an angled strip along the edge.
