Red Bull RB8 Renault

[aral]

Speed is also reporting DDRS on the RB8. You can see the inlet cover on the end of the flap.

Double DRS is when the front and rear wings are subjected to drag reduction. Red Bull are using a system that takes from activation of the DRS, via holes a la Mercedes, but instead of thenblowing the front wing,they are directing the air to below the rear wing, similar to Mercs passive system. So really it is just a refinement to the official DRS system.

This will give them the edge in qualifying surely. Getting pole is everything, it's essential for preserving the tyres. Vettel has a big chance to make it 3 in a row. Having said that, it should be kept in mind that Vettel probably never used DRS in the race but was still damn fast.

You can still count it as a DDRS though; the holes only open up when DRS is active. The only difference reallt is what it stalls. It gives a double effect when DRS is active. It is the same principle all together.

Red Bull solution might not be as effective as the one of Mercedes, but they saved themselves from having to repackage the car and designing a new chassis which had to go through crashtest again.

Here is my analysis and drawings on the DDRS system:

BTW guys please feel free to integrate any of my drawings in the forum to continue the discussion here.

While Lotus and Mercedes have been experimenting for some time with passive 'double-DRS' devices, which have proved difficult in terms of set up, Red Bull have devised a very clever and easy system for the RB8. Believed to have been introduced in Singapore, but only discovered this weekend in Suzuka, Adrian Newey's new solution is activated by the movement of the flap when the DRS system is operated and has been spotted thanks to the bigger surface of bodywork used to fix the flap. When the hole (see yellow highlighted area) opens, the air flows through the endplate to the beam wing, where it blows onto the central 12-cm section of the diffuser, which is free of aero limitations. The new device is believed to have helped the RB8 to register the fastest top speed in qualifying.

It is strange Red Bull has developed a DDRS system since such devices are banned for next season, although the system has really improved their qualifying performance because of free DRS use during qualifying.

I think it is only logical. You update what you can to get the most out of your season. We've seen in 2010 Torro Rosso adding in Korea an F-duct device; by that time it was already known that F-ducts would be banned next season. They did it anyhow in a bid to jump 1 or 2 teams in the constructors championship. That Red Bull is doing this to jump Alonso and to secure the constructors championship makes it only very logical that they bring an update that really works (rumored to have brought them 0.5 seconds in qualifying) and I believe McLaren and Ferrari will jump on the wagon.

It is also said they already tested it in Singapore. Nobody noticed that. To bring such an update and to keep it hidden is VERY impressive.

[amouzouris]

Yes, you are right about doing everything to jump Alonso! ill have to rephrase my post in the blog because im not giving out what i was thinking! Red Bull is a big team and can afford to 'waste' some money (waste only because it will be banned next year but pretty much worth it for this year with the big improvement the have in qualy)

I went through a lot of the photos from Singapore but didn't find any evidence of DDRS, im not saying they didn't have it their, but because of the light effect maybe n one noticed it

I was thinking the same thing. Some people (myself included) even tought at a point Mercedes dropped their own DDRS. It was that hard to notice it. The pipes run on the black inner side of the rear wing endplates, so already not so easy to spot them, let alone under artifical light.

Some different angles of RB8 from Singapore when the team did Flow Vis run.









and close up from today

This where the blowing most likely happens, flow separation, less drag:

Looking at the end plates at Singapore, the DDRS was also in use there. Well disguised by Red Bull. Nobody spotted it!

[Shrieker]

Newey stole my idea lol. I came up with it at least 6 months ago.

[Dragonfly]

Which means they are reading the forum

[munudeges]

The front wing and nose they have now is looking a lot like what they had last year.

[user001]

The front wing and nose they have now is looking a lot like what they had last year.

cause they managed to regain all or most of the downforce (at the rear) from last year? Or what could be the reason?
