If they use a "heavier" BW it is very likely that they'll use FW with higher DW than they used on tests.
Any pictures someone?
Aerofoils have no camber (neutral), angles don't need to be (except the camera pod angles I think). I think you are right about the driveshaft and brake duct winglets, although there is no lateral expansion in the diffuser at all since last year. Teams use big radii clearance in rules to add some curvature locally, but that's just to speed-up the airflow locally and reduce the pressure just a bit more. Outwashing diffuser would have an entire fence curved outside and this is not the case, rules don't allow that.nico5 wrote: ↑02 Mar 2023, 13:45Two very naive questions about that heavily downwashing driveshaft:
I was under the impression that suspension/driveshaft elements were mandated to have a neutral angle, is it not the case?
Is that bit considered far enough from the diffuser exit so that some downwash might actually help drive the rear corner winglets by increasing their AoA rather than inducing separation in the diffuser edge itself, which is most sensitive as it's where you also go for lateral expansion at aggressive radii, although far less than pre-'22. The fact that the trailing edge only dips down towards the outside would point to that. Would the downward transition combined with the relatively high camber of that wing body also help achieving that 45°-outwash effect that they're aiming for in the diffuser corner?
That FW in the background looks like one with higher DW than the one they used ov tests.
You got it right first as usual Vanja
