Abstract
A lateral thrust rudder for a ship includes a cross-channel extending transversely through the ship from one side thereof to the other side and a water conveying mechanism such as a propeller is provided in the cross-channel. A guide vane is pivotally mounted on a horizontal axle at each end of the cross-channel and extends inwardly into the cross-channel. The lower part of each end of the channel is rounded so it flares outwardly. Normally the guide vanes are controlled solely by water flow through the cross-channel but, where necessary, a drive mechanism can be provided for the vanes.
Claims5
A lateral thrust apparatus for a ship, comprising an opening provided in one side of the ship, a channel in the ship communicating with said opening, means for selectively effecting a flow of water in one of a first direction into said channel through said opening and a second direction out of said channel through said opening, and a vane freely pivotally supported at one end in said opening for movement about an axis which extends across said opening, said vane projecting into said channel from said axis and being movable in response to water flowing respectively in said first and second directions between a first position generally parallel to said first direction of flow of said water and a second position inclined with respect to said second direction of water flow and substantially obstructing the flow of water through a portion of said opening which is disposed substantially on one side of said axis, whereby when said vane is in said second position and water is flowing in said second direction, said vane forces substantially all of the water to pass through the portion of said opening disposed on the side of said axis opposite said one portion thereof.
