Title: 2-shaft 2-rudder system high speed ship
Inventor: KIHARA KAZUYUKI
IPC: B63H25/38
Filed: 1984-08-22
Abstract: PURPOSE:To obtain sufficient efficiency of a rudder when a smaller rudder angle is taken in normal sailing or when a larger rudder angle is taken in high speed sailing by making curvature of the outside of the rudder smaller than that of the inside. CONSTITUTION:At the rear of a pair of right and left propellers 2L, 2R, a pair of right and left rudders 3L, 3R are disposed inside the propeller shaft center lines 4L, 4R. The rudders 3L, 3R have non-symmetrical blade type cross sections where outside curvature is set smaller than inside curvature on their horizontal cross sections. Therefore, pressure drop rate becomes less and cavitation is hard to be generated, and lift generated on the outside face of the rudder becomes less even if a larger rudder angle is taken in high speed sailing.
