Calculate the maximum lift to drag ratio for a business jet wit... | Filo

The ratio of lift to drag L D for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. If a wing is pitched through a range of angle of attack, L D first increases, then goes through a maximum, and then decreases. Consider an infinite wing with an NACA 2412 airfoil. Estimate the maximum value of L / D. Assume that the Reynolds number is 9 ×10^6. | Numerade
