VESSEL SIDE THRUSTER Russian patent published in 2015 - IPC B63H25/42 

FIELD: process engineering.

SUBSTANCE: invention relates to ship building, particularly, to ship active control means. Ship side thruster comprises propulsors and electric drive fitted on the shafts. Said propulsors are composed of disc-like ring-shape bodies of spherical convex or concave shape outer surface that follows the ship hull shell plating outer surface shape. Rotational axes of said bodies are directed perpendicular to the plane tangential to shell plating at its intersection with the axes. Disc-like bodies are set to make their outer surface edges do not extend beyond the shell plating outer surface.

EFFECT: higher propulsive properties, increased ship useful tonnage, lower noise of side thruster.
