Thruster is a thrust device that has a propeller in the tunnel which penetrates the body of the ship laterally. Ships with thruster easily can be steerage in the situation with a wave and the wind. It also becomes possible to keep the shipturn at a fixed point so that it can get ashore and leave shore quickly. Recently thruster is becoming popular, but the small type thruster is not studied enough. In this study, we made an investigation into the thruster which is used ships around 10 tons by using numerical flow analysis. In this paper, show the thrust and drag of each part of the thruster are shown so that we focus on the difference of the thrust in each flow direction is clarified.
