The invention discloses a ducted fan type propelling device. The propelling device comprises an annular shell, an air supply assembly and a wake flow direction changing device, wherein the air supplyassembly is arranged in the annular shell, the wake flow direction changing device is arranged at the tail of the annular shell, the axial section of the annular shell is a wing-shaped section, the wake flow turning device comprises a rudder blade and a steering device for driving the rudder blade to rotate, two ends of the rudder blade are rotatably installed on the annular shell, the rudder blade guides airflow flowing out of an annular body, due to the fact that the direction of the airflow is changed, the reverse thrust direction of the airflow is changed, then the movement direction of the ducted fan type propelling device is changed. The propelling device is advantaged in that the propelling device is simple in structure and convenient to operate, the ship comprises the ducted fan type propelling device installed on the ship body, the ship propelling device is convenient to install, the service life of the ship can be prolonged, and damage to underwater organisms is avoided.

    本发明公开一种涵道风扇式推进装置及船舶,涵道风扇式推进装置包括:环状壳体、供风组件、尾流变向装置,供风组件设置在环状壳体内部,尾流变向装置设置在环状壳体尾部,环状壳体轴向截面为翼型截面;尾流变向装置包括舵叶和驱动舵叶转动的转向装置,舵叶两端可转动的安装在环状壳体上,舵叶对环状体中流出的气流进行导向,由于气流的方向改变,使得气流反向推力方向发生改变,进而改变涵道风扇式推进装置的运动方向,使推进装置结构简单操作方便;船舶包括安装在船身上的涵道风扇式推进装置,船舶推进装置安装方便,可提高船舶使用寿命并避免对水下生物造成伤害。
