The efficient twisted rudder comprises a rudder blade, the rudder blade is vertically arranged, the cross section of the rudder blade is in a bilateral symmetry wing shape with the large front portion and the small rear portion, a rudder stock is connected to the front side of the upper surface of the rudder blade, and the rudder blade takes the axis of the rudder stock as the center; the upper middle portion of the rudder blade twists leftwards from top to bottom, the lower portion of the rudder blade twists rightwards from left from top to bottom, and the lower edge of the rudder blade is located on the right side of the axis of the rudderstock. Or the upper middle part of the rudder blade twists to the right side from top to bottom, the lower part of the rudder blade twists to the left side from the right side from top to bottom, and the lower edge of the rudder blade is positioned on the left side of the axis of the rudderstock. The left side face and the right side face of the rudder blade are both subjected to counter-acting force of wake flow, and the cross section of the rudder blade is in bilateral symmetry and big-front and small-rear wing shapes, so that the rudder blade absorbs the kinetic energy of the tail flow of the propeller and generates additional thrust on a ship, and the effects of saving energy and improving the navigational speed of the ship are achieved.

    本发明公开了一种高效扭曲船舵,并公开了具有一种高效扭曲船舵的船舶,高效扭曲船舵包括舵叶,舵叶竖直设置,舵叶的横截面呈左右对称和前大后小的翼型,舵叶的上表面的前侧连接有舵杆,舵叶以舵杆的轴线为中心,舵叶的上中部由上往下向左侧扭曲,舵叶的下部由上往下从向左侧扭变换为向右侧扭曲,舵叶的下沿处于舵杆的轴线的右侧。或者舵叶的上中部由上往下向右侧扭曲,舵叶的下部由上往下从向右侧扭变换为向左侧扭曲,舵叶的下沿处于舵杆的轴线的左侧。舵叶的左右侧面均受到尾流的反作用力,由于舵叶的横截面呈左右对称和前大后小的翼型,舵叶实现吸收螺旋桨的尾流动能,舵叶对船舶产生附加推力,起到节能和提高船舶航速的作用。
