The invention discloses a pod thruster capable of improving hydrodynamic performance and an arrangement structure thereof. The pod thruster comprises a propeller and a pod underwater shell; the top ofthe pod underwater shell is connected with a ship body; the propeller is installed at the tail end of the pod underwater shell; the pod thruster structure further comprises a flow guide pipe, an upper support frame and a lower support frame; one end of the upper support frame and one end of the lower support frame are connected with the upper portion and the lower portion of the pod underwater shell respectively; the other end of the upper support frame and the other end of the lower support frame are connected with the upper portion and the lower portion of the flow guide pipe respectively;the periphery of the propeller is sleeved with the flow guide pipe; and a certain gap is reserved between the flow guide pipe and the propeller. According to the pod thruster, the flow guide pipe canbe supported through the upper support frame and the lower support frame, the section of the flow guide pipe is in a wing shape, and due to the fact that the inlet area of the flow guide pipe is larger and the outlet area of the flow guide pipe is small, when the rotating speed, the diameter, the blade shape and the like of the propeller are the same, the propelling efficiency of the propeller canbe improved through the flow guide pipe, and larger thrust is provided.
一种可以提升水动力性能的吊舱推进器及其布置结构,所述吊舱推进器包括螺旋桨和吊舱水下壳体,所述的吊舱水下壳体的顶部与船体连接,吊舱水下壳体的尾端安装螺旋桨,该吊舱推进器结构还包括导流管、上支撑架和下支撑架,所述的上支撑架和下支撑架的一端分别与吊舱水下壳体的上部、下部连接,上支撑架和下支撑架的另一端分别与导流管上部、下部连接,所述的导流管套装在螺旋桨的外周,且与所述螺旋桨之间留有一定间隙。本发明中,通过上支撑架与下支撑架可以对导流管进行支撑,导流管截面为翼型,由于导流管的结构进口面积大,出口面积小,在螺旋桨转速、直径、叶型等情况相同时,导流管的存在可以增加螺旋桨的推进效率,提供更大的推力。
