L/D=Cl/Cd= 16 : 1
Downforce 17000N at 160km/h (44m/s)
frontal area, I choose 1.5m2 (is it Ok?)
Cl= 17000N/ (0,5 x 1.2kg/m3 x 44m/s^2 x 1.5m2)
Cl=9,5
Cl/Cd=16/1....
Cd=0,59
Do you think this is ok?
I think the highest L/D I've ever seen quoted for an F1 car was 8:1 for the 82 Williams, and I think that was without wheel forces.
In the past wheels were not mounted to the wind tunnel model but separately on their own struts, in fact I think it's mid-2000s before every team had wheels fixed to the car.
Newey said L/D is 16:1 and 17000N downforce, the rest I calculate from these two..
