Well Grandharva, that flo viz pic certainly shows a much different pattern than earlier pics, which had the flo viz nicely even across the beam wing underside.

I also think that on the first picture DRD was only enabled for the left side of the car, as the flow viz on the right side of the beam wing (as far as we can see it) looks pretty much straight. Maybe they did this for comparision...

.. where do you think the charge is coming from? Perhaps inside the airbox? That way the method that Lotus is using would produce a similar response as airbox pressure builds during closed exhausts.

I think they use the airflow coming out of the airbox. The DRD is fed through a slit in the upper side of the swan neck. You can see it in the second picture. This way it's very easy to disable DRD. Just slap on a closed top panel to the swan neck and thats it. A matter of minutes. On top of that, with this DRD system they can slap on/off the monkey seat as they like. Impossible with all the other solutions we have seen so far.

In this pic you can see that the beamwing just has a slit through it. it's the same position as in the flowviz picture

But at all, i think this could be a great idea to use the drd. would it be legal?

Yes, the beam wing is slitted. But this has nothing to do with DRD.

This could be the DRD intake/trigger

That is the Swan Neck support from the gearbox to the Beam Wing giving the wing assembly rigidity, the same can be seen on the Sauber C31/32 and I believe Williams have done the same in the past too.

EDIT: After closer inspection of the image from my Sutton archive (Hi Res) it is plausibly a slit but could as easily be a reflection.

Just gone through the forward and rearward facing pictures and it's not a slot it's a piece of bodywork from the Engine Cover as it overlaps the Swan Neck it gives off the perspective of a slot:

So you saying that DRS + DRD give Red Bull maximum of 290 km/h in speed trap in Jerez. I would be very concerned if I was a fan of this team how much would they have without DRS use in Jerez, 270? If they come in Barcelona with that speed they can say goodbye and salute for 2014.

Yeah sure. They'll fight with marrusia. Stop posting BS.

On this picture you can't see the DRD inlet at all (maybe it was even closed at this time...), as those small winglets you are refering to, are mounted before the DRD inlet. Probably to guide the air into the direction of the actual DRD inlet and/or the monkey seat. Also those winglets were not mounted all the time during testing, as there are several pictures where they are missing.

[user001]

what are your thoughts about the exhaust design? its quite different from the other teams, isn't it?

Ok a little more digging now I've looked through and found the original of the image you posted. I have blown this up:


Looks like there could well be a duct split by a centralised vertical fence (Much like they use in the exhaust tunnel) This will likely be a response to to controlling the airflow in Yaw.

I've also blown up this picture showing the area with a cover on for comparison:


Furthermore I went looking for the outlets as used last season on the Beam Wing for their DDRS system and found:




I did speculate in my recent DRD article that teams may choose to look at the option of stalling the Beam Wing via DRD rather than using the periscope setup like RBR did with DDRS last season and so this only fuels that theory further - http://www.somersf1.blogspot.co.uk/2013 ... -drag.html

Imho the most elegant DRD implementation we have seen so far. Took me a while to figure it out.

Indeed, here is a better picture of the holey Beam Wing:

[Rikhart]

But isn´t it much more beneficial to blow the rear wing proper? Isn´t the beamwing producing much less downforce/drag? Maybe they intend to blow both? Anyway, very nice find gandharva, kudos!

It is more beneficial to stall the Mainplane but look at the issues Lotus etc have had trying to so, perhaps this is much easier to implement. (Especially as they already have the advantage of stalling the Beam Wing last season)

In theory this system could easily be expanded to also blow the rear wing. Add some tunnels into the rear wing sideplates and then blow off the air at the rear wing similar to how it's done on the beam wing now. But i don't know how efficent it would be by routing all the air from swan neck up to the rear wing...

[Matt Somers]

Good image and the one that has been alluding me in order to ascertain as to whether they were using front to back bleed holes again or whether it was an enclosed duct.

Looks like a swan neck mount to improve beam wing efficiency. Make a lot of sense with the way RB route their cooling.
