The invention discloses a design method of a rudder and a ship. The rudder comprises a rudder blade, and the design method of the rudder comprises the steps that the rudder blade is divided into a plurality of sections in the extension direction of the rudder blade, and at least one section is an asymmetric section; and the attack angles of the rudder blades at the positions of the sections are adjusted according to the incoming flow attack angles of the positions of the sections, so that the rudder can generate thrust in the advancing direction when the ship body advances. According to the embodiment of the invention, the rudder blade is divided into a plurality of sections, and at least one section is an asymmetric section; the attack angles of the rudder blades at the positions of the sections are adjusted according to the incoming flow attack angles of the positions of the sections, so that the rudder can generate thrust to assist a propeller in propelling, the propelling efficiency of a ship is improved, and a more remarkable energy-saving effect is achieved.

    本发明公开了一种船舵的设计方法和船舶。船舵包括舵叶,船舵的设计方法包括:沿着舵叶的展长方向,将舵叶分成多个剖面,至少一个剖面为非对称剖面;根据各剖面所在位置的来流攻角调整舵叶在剖面的所在位置处的攻角,以使在船体前进时船舵能够产生沿前进方向上的推力。本发明实施例通过将舵叶分成多个剖面,至少一个剖面为非对称剖面;根据各剖面所在位置的来流攻角调整舵叶在剖面的所在位置处的攻角,可以使得船舵产生推力,辅助螺旋桨推进,提高船舶的推进效率,从而产生更为显著的节能效果。
