Red Bull pulling all stops for Monza

Post

Red Bull pulling all stops for Monza - Development blog

Red Bull Racing appears extremely determined to break the competition and secure the titles as soon as possible to be able to focus 100% on the 2014 project. As Monza hasn't been the strongest of venues for RBR, the team has gradually been pinpointing its weakest points and improving those, resulting in the impressive form displayed by the RB9 on Friday.

The team have basically brought two new front wing configurations. The first one featuring a cut out upper flap as used by Sebastian Vettel most of the day. Another version was likely shipped in in the morning, and lacked the stacked elements, with only a vortex generator - featuring the logo of Simply, the team's new partner - remaining on the front wing. That as well was used by Vettel (see inset). Mark Webber meanwhile used the Belgian front wing specification.

At the rear, the diffuser that was already briefly tested at Spa-Francorchamps made its return, featuring a gurney at the outer edges of the diffuser. The outer edges are also tapering down more than the previous diffuser, directing the extracted air more rearward, rather than outward and into the wake of the rear wheel.

Finally, the rear wing. One would think that the very shallow rear wing from Spa-Francorchamps would be used again too, but instead it was not seen again. It may be that the team found its benefits too small, warranting a further improvement of the design. Still featuring closed endplates without louvres on the high pressure size of the wing, the main plane is now curved downward in the middle. It's similar in concept to the one seen at Spa, except that at Spa the profile was straight with the leading edge slightly curved up in the middle.

IIRC this shape of central cooling outlet was used in monza also last year - it is probably related to reduced upwash from the low downforce rear wing

The rb7 won in monza with an unusual setup - shot gearing. The rb9 is the first redbull that is very fast at monza but seems to have conventinal gearing. The re is no big vidible difference compared to last year in the looks of the car: also the rb8 had the smallest rear wing, but still was not very fast on straights. What has happened this year?

Where has that extra drag fo the more downforce-producing body gone?

a bit offtopic, but did anybody notice today, I mean the sound of Redbull engine when they are off throttle? It reminds me of blown diffusor in 2011... This is probably the most of their advantage at this low-downforce race.
What do you guys think of that? I know that blown diffusors are forbidden but it was just strange sound....

Heard it SPA as well, definitely some trick stuff going on there,

The Flow Viz pattern of that diffuser looks perfect. No inverse flow patterns from the outside.
In contrary the flow seems to point down and to the ouside. They appear to get the footplate vortex accelerated so well that it creates suction on the ouside.
Amazing.
If you compare that to the messsy Flow Viz patterns inside the diffuser we saw on the Ferrari some time ago it dawns on me where the difference between the two lies.

Are we sure that the shots are in the pitlane after the lap and not before the lap?

1.On other forum people said that they gaind in DF coz the barge boards beneath the nose and the T-tray endplates are producing a tunnel effect : Image
2.Maybe someone could help me with a photo but it seems to me that they have a big if not the biggest RW main plane of all competitors. What are the advantages on doing that?
