In this paper we deal with the interaction problems between twin propellers and twin rudders in a uniform flow, as a first step of the theoretical approach to the propulsive performance of twin screw ship. The propeller is treated as an infinitely bladed propeller which is represented by the bound vortex distribution. The rudder load is expressed by the Glauert's mode function, and the rudder thickness is represented by the center plane source distribution which satisfies the boundary condition on the rudder surface. By using these singularities, we make clear the effects of the relative positions of the rudder to the propeller plane and to the propeller center line, and of the distance of two propellers and rudder thickness on the rudder drag in the problems of the propulsive performance of twin propellers and rudders system.
