Last update 6/4/2023 what's new. Frequently, the question arises as to what airfoil or airfoils were used in the wing design of a particular aircraft. Jane's All The World's Aircraft has been a good source of this information, but in many cases ... Clark y airfoil generation. I have been trying to figure out how to make a sketch that will be an airfoil for a wing. specifically I need this sketch to allow me to change a few parameters and it would make the wing I want. I either need the parameters to let me enter a 4 digit NACA, or, Preferably, to enter the Chord Length, Max Thickness, and ...The Aerodynamic Characteristics of Full-Scale Propellers Having 2, 3 and 4 Blades of Clark Y and R.A.F. 6 Airfoil Sections, NACA Report No. 640., NACA-TR-640, January 1938.
