Maybe it is. If they can make the inside of the mirror that small, why not just make it small and not bother with the gap or the larger outer surface?
Unless there is a stipulation on size in the regs?
I think it's a bit of both most likely.

Oh, I love that idea! Hmmm, well, based on these results, you'd probably end up having slightly different pressure distribution on top and bottom part of the cone, which could lead to some small amount of lift or downforce created.

Just checked it, 3mm slot model created 17% more lift than 1mm model. It's a very very small amount (3N at 320kmh), but there could be room for exploitation other than drag reduction. Great idea amr!
No, there are practically no changes in airflow behind the mirror, it goes straight as an arrow, just with smaller turbulent wake most likely. This difference of 3N is very very very small for such high speeds. And intakes are high pressure zone.amr wrote: ↑23 Mar 2018, 15:00Thank you Vanja.
So, if the mirror is setup to create lift it will push the air slightly downwards towards the intake on top of the sidepods.
If the mirror is setup to create downforce it will push the air slightly upwards away from the sidepods.
I think the key is that we have to judge the mirror considering that on top of the sidepods there is probably a low pression area created by the sidepods top intake.
Ok, the forward facing intake is indeed a high pressure zone. But i believe that the up facing intake, the one on top of the sidepod is creating a low pressure zone.I think that inside the sidepod, the two intakes are connected such that the fast high pressure air coming through the forward facing intake creates a venturi effect and sucks air through the up facing intake, this in turn creates a low pressure zone on top of the sidepod.
Direct air on the other side in what way? Could you make a simple drawing?iulian_florea wrote: ↑23 Mar 2018, 22:52I am almost sure that the upper sidepod intake directs air on the other side of the radiator than the lower intake.
Anyone has a different opinion on that one?

Maybe the mirror is design to create a downwash vortex to better feed the up facing intake, while reducing drag.
Great work! You are a true scientist and engineer.

First of all your good work rubbishes the air deflector to side-pod theory. Secondly I would have liked to have seen the model without any slot, and finally I am also interested in your last conclusion, with the turbulent factor value - in layman's terms was it good or bad?
