Abstract: This work is mainly concerned with experiments made with single-screw propellers and twin rudders located in the propeller race. The paper includes only the case of rudders which were placed just behind the propeller with zero angle of attack. The experiments have shown the possibility of obtaining an appreciable improvement in the efficiency and also in the thrust of the propeller for some range of rudder locations.
