Embodiment Construction

[0032] Figures 1 to 3 (referred together in the remainder of the description) shows a schematic perspective view of the stabilizing surface of the stabilizing device in each of three different positions in the first pivoting direction.

[0033] The watercraft or watercraft 12 includes a conventional hull 14 . In order to significantly dampen undesired roll movements, the active stabilization device 10 is integrated in the hull 14 . Here, the stabilizing device 10 comprises, for example, a stabilizing surface 16 which is approximately rectangular and fin-shaped. If necessary, the stabilizing surface 16 can also have a polygonal outer contour with more than four corners. The stabilizing surface 16 is pivotable about a pivot axis S and rotatable about an axis of rotation D using a suitable, preferably strong hydraulic positioning device 18 comprising a drive journal 20 .

[0034] The stabilizing surface 16 is preferably connected in a straight line to the drive journal 20 in ...

Abstract

The invention first relates to an active stabilizing device (10) for primary damping of rolling movements of a watercraft including a hull, in particular of a ship, wherein the stabilizing device includes at least one positioning device (18) including a drive journal (20) and including a stabilizing surface (16) attached to the drive journal (20) in the region of 0 its root (22), wherein the stabilizing surface (16) includes a leading edge (40) and a trailing edge (42), and the stabilizing surface (16) is disposed under water (26). According to the invention it is provided that the stabilizing surface (16) having an angle of attack (gamma) set by the positioning device (16) is pivotable about a pivot axis (S) between a first and second position (80, 86) and is rotatable by the positioningdevice (18) about an axis of 5 rotation (D). Consequently the leading edge (40) can always be oriented essentially in the direction of the pivot direction (82, 90) of the stabilizing surface (16), which stabilizing surface (16) is moving under water (26), which results in a considerable reduction of the flow resistance. A particularly energy-saving operation of the stabilizing device (10) is thereby possible. Furthermore the invention involves a method for operating the active stabilizing device (10).

Description

technical field [0001] The invention relates above all to an active stabilization device for primarily damping the rolling motions of a vessel with a hull, in particular a ship, wherein the stabilization device comprises at least one positioning device comprising a drive journal and comprising an attachment in the region of its root A stabilizing surface to a drive journal, wherein the stabilizing surface includes a leading edge and a trailing edge, and the stabilizing surface is disposed underwater. Furthermore, the invention relates to a method for operating an active stabilization device primarily for damping the rolling motion of a vessel with a hull, in particular a vessel, which does not move substantially in the water. Background technique [0002] In order to damp particularly undesired rolling motions of boats, especially larger motor-driven boats, it is known to use active stabilization devices comprising fin stabilizers attached to the hull of the boat below the w...
