The invention relates to a propeller assembly (10) for a marine vessel (1), comprising: a body (12) comprising a duct (20) having a longitudinal axis (L) and a first end (20.1) and a second end (20.2); a support structure (14) for the propeller (16), the support structure comprising a propeller shaft (18) at a centerline of the duct (20); a propeller (16) positioned in the duct (20) and attached to a propeller shaft (18), where the propeller (16) comprises at least three blades (22) and a hub (24) supported to the shaft (18), and further comprises a circular rim (26) to which the radial ends (22 ') of the blades of the propeller are attached, where there is provided a circumferential groove (28) in which the radial ends (22') of the blades of the propeller (16) are fixed to the hub (24). A circumferential groove opening inside the pipe between a first end (20.1) and a second end (20.2), a circular rim (26) being arranged to extend radially into said groove; and at least one gas inlet (30) arranged to lead to the slot (28). The invention also relates to a transverse tunnel thruster and a steerable azimuth thruster provided with the thruster assembly.

    本发明涉及一种用于海洋船舶(1)的推进器组件(10),该推进器组件包括:主体(12),该主体包括管道(20),该管道具有纵向轴线(L)以及第一端(20.1)和第二端(20.2);用于螺旋桨(16)的支撑结构(14),该支撑结构包括在管道(20)的中心线处的螺旋桨轴(18);螺旋桨(16),该螺旋桨定位在管道(20)中并附接到螺旋桨轴(18),其中,螺旋桨(16)包括至少三个桨叶(22)和被支撑到轴(18)的轮毂(24),并且进一步包括圆形轮缘(26),螺旋桨的桨叶的径向末端(22')附接到该圆形轮缘,其中,设有周向槽(28),该周向槽在第一端(20.1)与第二端(20.2)之间在管道内部开口,圆形轮缘(26)布置成径向地延伸到所述槽中;和布置成通向槽(28)的至少一个气体入口(30)。本发明还涉及设有推进器组件的横向隧道推进器和能转向的方位推进器。
