In designing a ship, it is very important to predict the performance of a rudder from the points of view of both propulsive performance and maneuverability. In this report, the flow field around a rudder and the pressure distribution on a rudder with rudder angle behind propeller are mainly treated theoretically. For representing the propeller, the simple propeller theory of the infinite number of propeller blades is used with roughly considering a contraction in slipstream. For a rudder with rudder angle in the non-uniform propeller slipstream, the panel method by L. Morino is applied to calculate the flow field and the performance of the rudder, including the viscous effect by the two-dimensional boundary layer calculation. As for the mutual interaction, the calculation on propeller and rudder is iterated so as to converge the pitch of propeller slipstream. The calculated results of the flow velocity around the propeller-rudder and the pressure distributions on the rudder surface with/without rudder angles are compared with the experimental data.
