Go easy on me I'm only 16 ;) I am utterly confused with the concept of "Airfoils", I have been doing some research on the web and so far all I have found is confusing descriptions that I do not understand and people arguing over which aerodynamics model for Airfoils is correct. The arguing and such only seem to increase my confusion. What I have taken from this so far is that the the Equal Transit Theory is incorrect, can somebody please explain to me how an Airfoil actually generates lift? Also I am confused about planes flying upside-down and flat Airfoils still managing to provide lift. Thank you for your assistance!
