In this paper, a design method to obtain the maximum static thrust ducted fan is proposed. In this method, the shape of the optimum blade is obtained by minimizing the objective function. The objective function includes the effect of the leading edge suction that acts on the duct's rip. The shape of the optimum blade is tapered, however, a small expansion is confirmed at blade tip. The amount of this expansion depends on the radius of duct's rip. From the optimized ducted fan, it is concluded that the duct generates nearly half of the total thrust, which is also predicted by the simple momentum theory.
