The invention provides a wake flow optimized variable dip angle rudder-attached thrust fin. The wake flow optimized variable dip angle rudder-attached thrust fin comprises a rudder and a boosting fin, a servo motor is arranged in the rudder, the two sides of the rudder are each provided with one boosting fin, the front ends of the boosting fins are installed on an output shaft of the servo motor, the servo motor is used for driving the boosting fins to rotate around the front ends so as to adjust the dip angle beta of the boosting fins, and the dip angle beta ranges from 0 degree to 8 degrees. According to the technical scheme, the inclination angle of the boosting fins on the side face of the rudder can be changed to achieve the purpose of self-adaptive wake flow optimization, and the ship boosting efficiency is improved by recycling rotation energy of the wake flow of the propeller.

    本发明提供一种尾流优化的可变倾角舵附推力鳍,包括舵和助推鳍;所述舵内部设置有伺服电机,所述舵两侧分别设置有一个所述助推鳍,所述助推鳍前端安装于所述伺服电机的输出轴,所述伺服电机用于驱动所述助推鳍绕前端转动从而调节所述助推鳍的倾角β,β为0~8°。本发明的技术方案能够改变舵侧面的助推鳍倾角达到自适应优化尾流的目的,并且利用回收螺旋桨尾流的旋转能量,提高船舶助推效率。
