I am working on a project and just need to understand one concept that I cannot find an answer to anywhere and hoping you could answer for me.
The project I'm working on is with airfoils and the main on NACA 63-021. In short, from what I have read as the foil get taller/thicker it creates more lift and can handle higher angles of attack as well.
My question to you is: if a foil like this which is symmetrical top and bottom foil shape, what direction of lift is increasing as the foil shape gets thicker? is the lift seen as forward motion lift/thurst?
You help on this would be greatly appreciated!
