The shape of a symmetrical four-di NACA airfoil is described by the equa- tion yote (0.2969, –0.1260-0.3516(3)*+0.2843(3) -0.1015(3) Insert Tools Desktop Window Help DERE NACA Airfoil where c is the cord length and t is the max- Figure imum thickness as a fraction of the cord Ele Edit View length (tc = maximum thickness). Sym- Dada metrical four-digit NACA airfoils are des- ignated NACA 00XX, where XX is 100t (i.e., NACA 0012 has + - 0.12). Plot the shape of a NACA 0020 airfoil with a cord length of 1.5 m.
