This arrangement concerns a flow guide surface for ship propellers, at least for twin propellers, the propellers being mounted by means of propeller brackets. It is provided for to arrange, at least in the region between the arms of the propeller brackets, a sectioned arcuate guide surface. This guide surface possesses a mean camber line converging backwardly towards the propeller shaft and the outlet edge has a distance to the propeller shaft amounting to between 70 and 130% of the propeller radius. This arcuate section of the guide surface is connected, on the side facing the ship's hull, to an approximately horizontal radial part. |
