Abstract

Ship maneuverability is mainly determined according to hull-propeller-rudder system of a ship and directly related to the ship safety during the operation in the ocean. Among hull-propeller-rudder system the rudder system had direct concern with the ship maneuverability and a special rudder has been recommended to improve the ship maneuverability. In this paper the study of flapped rudder’s 2-dimensional section was accomplished. Model tests had been carried out with different angles of attack of a main foil and flap’s deflection angles to predict the performance of the flapped rudder and the 2 frame particle tracking method had been used to obtain the velocity distribution in the flow field during model tests. Re=1.027×10⁴ had been used during the whole experiments and measured results had been compared with each other.
