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 ... Oct 25, 2011 · The Clark Y airfoil is a great choice for the RC model airplane designer. The Clark Y has high camber, which allows for an efficient lift to drag ratio on a typical lightweight RC model.

Figure A-1 shows data for the NACA 0012 airfoil, a classic symmetrical shape that is used for everything from airplane stabilizers and canards to helicopter rotors to submarine “sails”. Note that for the symmetrical shape the lift coefficient is zero at zero angle of attack. These graphs show test results for several different Reynolds ...Back to Results. Pressure Distribution Over Airfoils with Fowler Flaps Report presents the results of tests made of a Clark y airfoil with a Clark y Fowler flap and of an NACA 23012 airfoil with NACA Fowler flaps.
