VESSEL WITH FLOW-DEFLECTING HYDRODYNAMIC ARRANGEMENT OF BOW UNDERWATER WING Russian patent published in 2017 - IPC B63B1/40 B63B1/32 B63B1/06 

FIELD: transportation.

SUBSTANCE: vessel with a hydrodynamic flow control channel at the bow of this vessel is proposed. The channel comprises a pair of sidewalls (2, 3) with a part of the wing profile on each side of the vessel bow, connected to a horizontally oriented or inclined wall section (1) with the part of the wing profile. The channel is made with the possibility of movement in the vertical direction between the position (a) and the position (b) due to differentiating the flow therein from the out-of-channel flow interacting with the vessel bow having horizontally extending rectilinear or convex sidewalls (102, 103). The side walls (2, 3) have their rear edges at a constant distance from the side walls (102, 103) of the vessel bow, while, due to aesthetic requirements, they may comprise coatings (2', 3') of the part of the wing profile or inner sheet laminates (20', 30') projecting outward while navigating the vessel and retracted inwards when the vessel is immobile in the port.

EFFECT: reducing the wave formation and frictional resistances.
