Red Bull RB15

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.

Look at the rear wing at high speed.
Soft rear suspension, don't you think?

No, that's the actual wing flexing, that's why they've all adopted these designs with the split, front mounted endplates, etc.

Maybe that is also why we saw the merc wing fail. the weaker the entire structure the more (downward) flex it has (and the less drag at high speeds) but at some point the DRS attachment point can get out of alignment too much and fail (apparently).

flex on front and rear wing are predetermined and aren't allowed to exceed a certain flexibillity

thats why you saw at TR those target points on the rearwing at the russia GP, to see how much the rear wing flex

Yea, lets look back at how RedBull passed the front wing tests around 2010-2013, you can pass the test, but sometimes the force on the wings in real life exceeds/differs from the way a clinical test is done.

Red Bull needs to switch to the box kite side pod style the way Mercedes and Ferrari have done. The rest of the grid are using that fighter jet where the top and side elements are detached.

Box kites are incredible under yaw, the trick is feeding them enough air in the right place.

Of course easier said than done as going full box kite might not work with other bits on the car, and bargeboards.

It's not just the flexing of the rear wing, but also (as you mentioned) a soft rear suspension. You can tell by the lack of rake on this pictures compared to the rake at low speeds. Image

Wow, that's some borderline cheating!

A rear wing that lowers its angle of attack at speed, then returns to its proper position for corners, sounds like quite an advantage.

Is there no deflection test for the rear wing? :wtf:

There is, not only for the RW but for many other parts as well.
Doesn't stop the teams from going to the limit but as everyone is doing that you don't gain that much I imagine.

Well was mentioned by danish f1 journalist, who spend his whole life with f1 and good contacts with haas offcourse through kevin, that haas only has one hydraulic rear susp from ferrari and i think was in spa that grosjean used and that alone gave 6kmh according to peter nygaard, on the straight due to lowering the rear under load. If you add to that a little flex in the rearwing element and mount and youre looking at quit a significant gain without harming corner performance
Edit
Just checked, and yes peter mentions that main purpose of hydraulic rear is to lower during load and that gave grosjean 6-7 kmh on the straight compared to magnussen in qual

the car with plastic around the wheels is the showcar, it is an RB13 with 2019 "look alike" wings

Yes, there is a deflection test, but the way the wings are designed with the cantered endplates and front mounts they twist down and out and lower the rear wing from not just the downforce but the drag generated by the wing as well, that's why that style of endplate has been adopted almost universally.

The haas suspension and rw flex is indeed very similar to the Ferrari suspension because they share a lot of parts.
