Re: Rudder Airfoil Debate.... | Quote: Originally Posted by wings19 | | | | | | Lift is created when the air over the top of and airfoil is traveling faster than that over the bottom reducing the pressure on the top(bernoulli). Therefore, an airfoil would make more lift at the same AOA as a flat plate because the air has to travel a greater distance over the top of that surface than the bottom making a much lower pressure compared to a flat plate where the air wouldn't travel as far. When the air has to travel further it speeds up. I forget why it speeds up but I know it does because I was taught why in my ground schools but can't remember why  | | | | | Ditto
