 Re: Rudder Airfoil Debate....
The flat plate is still producing lift though. Maybe not as much, but it definitely is. The flat plate and symmetrical aifroil (flat plat is symmetrical as well) both produce 0 lift at no AOA. Once a positive AOA is introduced there is lift. With the flat plate this also brings tons of drag= IDEAL FOAMY!
Disclaimer: Yes I know the " air has to travel faster to meet at the same point at the TE" is a hightly debated but extremely common explanation.
