F1-02 downforce

[NaN]

Set efficiency to 0.8.

Still looking for a realistic medium setting. This one has total L/D=3.6, wing L/D=10

Code:

[wing.center]
position = 0.00, 0.00, -0.40
frontal-area = 1.0
drag-coefficient = 0.6

[wing.front]
frontal-area = 0.20
drag-coefficient = 0.01        # most wing drag induced(efficiency)
surface-area = 1.25            # tire load front/rear 44/56
lift-coefficient = -1.5
efficiency = 0.9            # L/D = 1/(1-efficiency)
texture = body00.png, body-misc1.png
mesh = wing_front.joe
position = 0.0, 2.25, -0.44
mass = 20

[wing.rear]
frontal-area = 0.3
drag-coefficient = 0.01
surface-area = 1.75            # tire load front/rear 44/56
lift-coefficient = -1.5
efficiency = 0.9
texture = body00.png, body-misc1.png
mesh = wing_rear.joe
position = 0.0, -1.84, -0.1
mass = 20

Maximum L/D should be somewhere between 0-12 -> efficiency 0-0.92. The efficiency has to be adjusted with the lift coefficient. At Cl=1.5 it should be much worse than what I have. I think about L/D=5 -> efficiency=0.8. But the F1 have multi-element wings which might differ.


To get the body drag right. I've tried to replicate Penske-Reynard-Honda 01 super-speedway configuration(almost no wing): 1000 lbs. @ 230 mph, with 950 lbs. of drag.
