The pod thruster comprises a tail fin, a rudder body, a propeller and a fairing cap, the rudder body is located behind the propeller and provided with a power device used for driving the propeller to rotate, the tail fin is connected with the rudder body, and the fairing cap is connected with the rudder body. An additional impeller driven by the wake flow of the propeller is arranged between the rudder body and the propeller, the additional impeller and the propeller are coaxially arranged and freely rotate, the additional impeller comprises a wheel disc and blades, the part, close to the wheel disc, of each blade is a turbine blade, and the impeller and the blade are coaxially arranged. The parts, extending outwards in the radial direction of the additional impeller, of the turbine blades form propeller blades. The invention can absorb the wake flow of the propeller to generate additional thrust, improve the propulsive efficiency and save energy.

    本发明公开了一种具有桨后附加节能装置吊舱推进器,包括尾鳍、舵体、螺旋桨和导流帽,所述舵体位于所述螺旋桨后方,所述舵体设有用于驱动所述螺旋桨转动的动力装置,所述尾鳍与所述舵体连接,所述舵体与所述螺旋桨之间设有由所述螺旋桨的尾流驱动的附加叶轮,所述附加叶轮与所述螺旋桨同轴设置并自由转动,所述附加叶轮包括轮盘和叶片,所述叶片靠近所述轮盘的部分为涡轮叶片,所述涡轮叶片沿所述附加叶轮的径向向外延伸的部分构成螺旋桨叶片。本发明可吸收螺旋桨尾流产生附加推力,提高推进效率,节省能源。
