Question: Consider an NACA 2 4 1 2 airfoil with a chord of 0 . 6 4 m in an airstream at standard sea level conditions.

Consider an NACA 2412 airfoil with a chord of 0.64 m in an airstream at standard sea level conditions. The freestream velocity is 70 m/s. The liN per unit span is 1254 N/m. Calculate the angle of AOA and the drag per unit span.
For the airfoil and flow conditions given in above Example, calculate the moment per unit span about the aerodynamic center.
