The invention discloses a rudder blade with flow guide side plates. Two flow guide side plates (2) are arranged at the rear edge of the rudder blade (1), are respectively arranged on two side surfaces of the rudder blade, and are symmetrically arranged on the rudder blade; the flow guide side plate is arranged along the trend of the rear edge of the rudder blade, the plate surface of the flow guide side plate is opposite to the side surface of the rudder blade, and the flow guide side plate and the rudder blade are arranged at an interval; the flow guide side plate is fixedly connected to the surface of the side face of the rudder blade through a series of connecting plates (3). Symmetrical flow guide side plates are arranged on the rear edge of the rudder blade, under the flow guide effect of the flow guide side plates, the vortex shedding effect of the rear edge of the rudder blade can interfere with each other, and therefore generation of a Karman vortex street can be hindered, vortex-induced vibration is avoided, the uncontrollable condition in the ship running process is prevented, and the ship running safety is improved. And in addition, the overall structural design of the rudder blade does not need to be changed, and implementation is convenient.
本发明公开了一种具有导流侧板的舵叶。该舵叶(1)的后缘处设置有两块导流侧板(2),两块导流侧板分别设置在舵叶的两侧面上,两块导流侧板在舵叶上对称布置;导流侧板沿着舵叶的后缘走向布置,导流侧板的板面与舵叶的侧面相对而置,导流侧板与舵叶之间隔空设置;所述导流侧板通过一系列连接板(3)固定连接在舵叶的侧面表面上。在所述舵叶的后缘处设置有对称的导流侧板,在导流侧板的导流作用下,舵叶后缘的涡流脱落作用会发生互相干扰,这样就能够阻碍卡门涡街的产生,从而避免导致涡激振动,防止船舶行驶过程中发生不可控的情况,提高了船舶行驶的安全性,而且无须改变舵叶整体结构设计,便于实现。
