Back to plain Jane. At least for a while
better example of anhedral-ness Notice how the middle section
is higher from the ground than the outer? This is the same idea Formula
One teams use when designing their front wings. It goes back to the
aerodynamics theory that a wing will develop more downforce the closer
it is in proximity to the ground.
Getting back to the anhedral idea though. The theory also says that there is a height (dependent on wing section, conditions etc.) where the wing is too close to the ground and it will stall, producing less downforce and more drag (opposite of what you want). The airflow going underneath it will pack up and slow down. But you still want to get as much downforce as possible out of your front wing (or splitter in our Courage's case) with out the disadvantage of a pitch sensitive wing? Well, make it anhedral. Let the outer sections run close to the ground producing more downforce, but leave a section in freer air so that even if the wing does stall in certain parts, the middle section will still function, producing downforce and providing airflow to the under body (preventing it from stalling as well).
...And this is how they ran it in the race.
