涉及设置有主副推进装置的船舶推进的改进
摘要：
本发明涉及一种拥有具有船头(201)和船尾向所述船尾的至少一个主推进装置(3)，以及-位于朝向所述船尾的至少两个副推进装置(4)，每个副推进装置(4)的推力容量小于所述至少一个主推进装置(3)中任何一个的推力容量的30％，-其中，由于在垂直于船体中心线(CL)的平面上凸出，所述推进装置(3、4)布置成使得每个副推进装置(4)的水平延伸(HES)不重叠所述至少一个主推进装置(3)中任何一个的水平延伸(HEM)，-其中，所述至少两个副推进装置(4)布置成使得来自所述副推进装置(4)的螺旋桨涡流(8)离开副推进装置(4)的区域(7)在所述船舶正以全速或极速向前直行时至少部分地位于所述船体(2)的边界层(6)内。(202)的船体(2)的船舶，所述船舶包括-位于朝
摘要（英）：

The invention relates to a ship presenting a hull (2) having a bow (201) and a stern (202), the ship comprising at least one main propulsion device (3) located towards the stern, and at least two secondary propulsion devices (4) located towards the stern, the thrust capacity of each secondary propulsion device (4) being less than 30% of the thrust capacity of any of the at least one main propulsion device (3), wherein the propulsion devices (3, 4) are arranged, as projected on a plane which is perpendicular to a hull centreline (CL), so that the horizontal extension (HES) of each secondary propulsion device (4) does not overlap the horizontal extension (HEM) of any of the at least one main propulsion device (3), wherein the at least two secondary propulsion devices (4) are arranged so that regions (7) where the prop washes (8) from the secondary propulsion devices (4) leave the secondary propulsion devices (4) are at least partly located, when the ship is moving straight ahead at full speed or flank speed, within a boundary layer (6) of the hull (2).
