When i say not much separation, i mean on this wing it is separating on the regions way after where the DRD is having it's major effect.
I'm getting separation near the trailing edge of the first plane, and similarly on the second.
The DRD effect is on the bottom, as the profile start to rise.
Regardless of what percentages we are talking about or how good a L/D ratio, this will vary across teams, the DRD does infact reduce drag, but the overall efficiency of the wing drops and this is to be expected.
What i wonder,is why don't teams just increase the speed at which it disengages? s
Surely that will give enough time for reattachment of the flow.
Another way of reattaching the flow much easier is to add an end plate in the middle of the wing.
This is what we saw mercedes doing in the winter tests. Once you give the air something to "grab" onto the flow will reestablish itself.
they have a little mini end plate on the wing. I think this may return in a bigger size later down in the season.
