| Outline of Final Research Achievements |
The rudder behind the propeller generates the thrust owing to the circumferential flow in the propeller slipstream. Some researchers developed the low drag rudders using the propeller-rudder interaction. This study presents the newly developed rudder 'High Thrust Rudder' which has U-shaped notch at the leading edge on the extended line of the propeller shaft center line in order to obtain the low drag more effectively comparing with the conventional rudder. Experiment and calculation are conducted in this study and the energy saving effect by the developed rudder was confirmed.
