Thanks for the floor pictures, they are very interesting!
I was convinced that my floor was lacking performance, because I didn't do as much development as I wanted, so I'm pleasently surprised by the results! I now need to find out why I am missing so much on the rear wing compared to Variante and Koldskaal.
- Is my beamwing too aggressive? I'm the only one with dark blue on both the diffuser trailing edge and the beamwing. I went aggressive because that's what F1 teams have done, but maybe it doesn't work with our cars and CFD model.
- Is my bodywork and cooling flow strategy sending too much loss to the rear wing? That's quite likely.
- Are my rear wing profiles just
? Again I haven't done may iterations so I may need to spend more time there.
Anyway, with these cars there are clearly 2 distincts philosophies :
1) Bias all the floor loading to the back, maximising massflow and energy with a high floor inlet and not very aggressive fences. Then you just need a big front wing to balance the car. This will degrade the front tyre wake but if the front of the floor doesn't do much it may not be a problem. Variante, Koldskaal and Tolo have gone this way and given they have won 4 races out of 5, this sounds quite a successful strategy.
2) Share the floor loading beetwen the fence region and the diffuser. The idea is that there would be less requirement to balance the car purely with the front wing. This should mean a less extreme front wheel wake which in turn would help with fence performance. Everyone else have gone this way and my car is the most extreme / successful example of that.
