It is intended to be the most "user-friendly" of its type. AeroFoil uses the vortex panel method and integral boundary layer equations to calculate drag, lift, and airfoil pitching moment at different angles of attack. Direct comparisons of up to three airfoils at a time may be performed. Lift and weight are two of the four forces acting on an airplane, the other two are drag and thrust (see Figure 1). The airplane generates lift using its wings. The cross-sectional shape of the wing is called an airfoil. A typical airfoil and its properties are shown in Figure 2, and are also described below.
