Lotus E20 VD

too high to be blowing at the diffuser...

First draw from Scarb

The Lotus E20 DRS appears to blow the diffuser, then blows over the beam wing when DRS is open.

scarbs take on it

what was that about it not blowing over the top of the diffuser?

[Owen.C93]

it is not stalling the rear wing, it is blowing over the top of the diffuser

They could do that 24/7 if they wanted, no need to make a stupidly complex DRS system.

I might be wrong, but it looks like the ducts lead down to the diffuser area

Oh I thought you meant the beam wing exit.

The only problem is Grosjean is faster whitout it! it's a waste of money!

3 pipes????!!?!?!?
and now I dont get how he is losing downforce at low speeds

[hammarby88]

the wing is at high pressure so when is on normal mode the pressure stops the air from coming up from the holes, when drs opens the pressure is lower since there is only one profile working the air comes up and pushes the air from the top of the profile to the bottom stalling the wing.

it is not stalling the rear wing, it is blowing over the top of the diffuser

They could do that 24/7 if they wanted, no need to make a stupidly complex DRS system.

Could do both no?
When DRS is closed, the air from the inlets on the rollhoop is blown out the big hole aka longer version of RBR outlet pretty much. When DRS opens ducts opens mercedes style but blows over the diffusor as N12ck said, meaning DRS with better grip. On top of that a third duct is revealed in the main plane rear wing which makes some of the air going trough that large tube from roolhoop go blow up onto the opened DRS flap mean it could stall the main plane slightly AND increase the pressure to the ducts leading to diffusor.

Sounds possible N12ck?

Well looking at this image I really can't see how it's ducted to the diffuser. There does seem to be one small hole above the starter motor slot that may be ducted but that's tiny compared to the rest of the inlet.

The endplates go all the way to the floor.

There is no flow-wizz paint on diffusor,so maybe Scrabs is wrong!

[Huntresa]

Air could come via that highlighted area.

why would the air go to the diffusor if it has another place to exit?, wounldn't it be easy if..... 1 scoope blows the diffuser RBR style and the other scoop blows the rear wing and it has 2 separate systems?
