Abstract
The invention concerned refers to a hydrofoil-based vessel stabilisation system which ensures vessel stability without the unnecessary ballast weight. The stability of the vessel is efficiently achieved by the use of hydrofoils (1) placed under the water, which are detached from the vessel, connected to the beams or an axle (2) in a way which enables their rotation. As the hydrofoils (1) are rotated in opposite directions and passing through the water, they are pulling one side of the vessel downwards and lifting the other side upwards, thus enabling the rotation of vessel in the opposite direction of the wind or other forces tilting the vessel. The hydrofoil-based vessel stabilisation system consists of a pair of hydrofoils (1) placed under the water and detached from the vessel, connected to the vessel by several beams (2), several axles (3), out of which two are horizontal axles (3) connected to the hydrofoils (1) in a way that the hydrofoils (1) rotate around the horizontal axles (3) by means of the control levers (4). The system uses the function of the weight (6) or at least one electromotor (11) together with a rack (10) for the rotation of hydrofoils (1). The said hydrofoil (1) rotation system also contains a central vertically placed axle (3) which is in rack-based connection with the bevel gears (12), which the vertical axle (3) rotates via at least one electromotor (11) or manually.
Description
HYDROFOIL BASED VESSEL STABILISATION SYSTEM
Description of the invention
Technical field
This invention refers to the hydrofoil-based vessel stabilisation system. Technical problem
There is a problem with the wind and waves tilting the vessel and thus decreasing the efficiency of the vessel's sail and hydrodynamics.
State of the Art
The problem regarding vessel stabilisation has so far been solved by using a keel with a weight on its bottom, the so-called ballast which puts up resistance against the wind as the vessel tilts.
The more state-of-the-art keels move the ballast in a translational manner due to the axle parallel to the water level, so it is possible to gain an additional list compared to the vessel list which has so far been the way used to keep the vessel straight despite a certain amount of wind in its sails.
However, there are still many problems such as:
- ballast efficiency when the vessel is in an upright position,
- ballast mass,
- moment compared to the ballast mass, and
- draught.
The invention concerned solves the said problems without the unnecessary ballast weight.
Detailed description of the invention
An efficient solution lies in the hydrofoils detached from the vessel under the water and placed in parallel on the left and right side of the vessel, connected to the vessel in their centre via a beam allowing the rotation of the hydrofoils. Hydrofoils are rotated in the front or back section via a control device. They can be rotated from the hydrofoil's inner side via the axles connected to the centre axle. When the control device is regulated by a weight, it is connected to the back of the hydrofoil, and that change of the hydrofoil's position results in the pulling of the side of the vessel which has been lifted downwards and lifting of the vessel's opposite side upwards. It is important to note that the hydrofoil beam allows for the rotation and that is connected in the hydrofoil centre so that the hydrofoils, while passing through the water, do not return to their central position, or assume the furthest upper or bottom position. That way the hydrofoils remain in the position determined by the control device and they straighten the vessel.

The invention concerned provides several manners of application of the hydrofoil- based vessel stabilisation system, with the use of a weight, a single electromotor, only one central axle, several axles and with the use of two electromotors. Figures 1 and 2 give an overview of the vessel stabilisation system with the use of a weight (6) which essentially consists of the hydrofoils (1 ) connected to the axle (3) in their centre, with each hydrofoil (1 ) supported by a beam (2) in a way which enables the rotation of the hydrofoils (1 ) which is realised in the front or back section via the control levers (4), each exiting one of the control cylinders (5) fixed in the vessel. Central levers (7), connected to the weight (6) which moves over the cylinders (5) and levers (4) and thus moves the hydrofoils (1 ), exit the other side of the cylinders (5). The cylinders (5) are filled with a gaseous or liquid medium (9) and they transfer the horizontal movement of the weight (6) and central levers (7) via the medium (9) to the movement of the vertical pistons (8a) and control levers (4) which move the hydrofoils (1 ). Hydrofoils (1 ) are connected to the beams (2) under the water in a way which enables their rotation initiated by the weight (6) in such a manner that when the weight (6) is set further from the central position, the hydrofoils (1 ) are rotated further more in the opposite directions. Figures 3, 4 and 5 give an overview of the placement of the hydrofoil-based vessel stabilisation system. Figure 6 gives an overview of a hydrofoil-based vessel stabilisation system regulated by an electromotor and a rack. Hydrofoils (1 ) which are in their centre connected to the axle (3) supported by the beam (2) thus enabling the rotation of the hydrofoils (1 ), and rotated in the front or back section by the control levers (4) which are connected to the control cylinders (5) fixed in the vessel itself. Central levers (7), connected to the rack (10) operated by an electromotor (1 1 ) which moves over the cylinders (5) and control levers (4) and thus moves the hydrofoils (1 ), exit the other side of the cylinders (5). The cylinders (5) are filled with a gaseous or liquid medium (9) and they transfer the horizontal movement of the central levers (7) over the pistons (8) via the medium (9) to the movement of the vertical pistons (8) and control levers (4) which
move the hydrofoils (1 ). Hydrofoils (1 ) are connected to the beams (2) under the water in a way which enables their rotation initiated by the electromotor (1 1 ) so that when the electromotor (1 1 ) is set further from the central position, the hydrofoils (1) are thus rotated further more in the opposite directions. Hydrofoils (1 ) pass through the water in a way that they are surrounded by water both from their upper and bottom side and they rotate in opposite directions, pulling one side of the vessel downwards and lifting the opposite side upwards, or vice versa.
Figures 7 and 8 give an overview of a hydrofoil-based vessel stabilisation system regulated by axles (3), a system which consists of hydrofoils (1 ), beams (2), several axles (3), bevel gears (12) and axle holders (14) so that by rotating the central vertical axle (3) over the bevel gears (12) supported by the axle holders (14) the rotation is transferred to the horizontally placed two axles (3) which are laterally connected to the hydrofoils (1 ) which rotate in opposite directions thus regulating the vessel list.
Hydrofoils (1 ) placed under the water and connected to the axles (3) rotate in opposite directions via the rotation of the central axle. Hydrofoils (1 ) can be rotated around the lateral axles (3) over the portable assemblies (13) which are transferring the rotation from the main vertical axle (3) over the bevel gears (12) and the horizontal axles (3) onto the hydrofoils (1 ).
The central vertical axle (3) is operated by an electromotor (1 1 ) over the bevel gears (12) supported by the axle holders (14) and it transfers the rotation to horizontal axles (3) which are laterally connected to the hydrofoils (1 ) which rotate in opposite directions thus regulating the vessel list. Hydrofoils (1 ) are connected to the beams (2) under the water in a way which enables their rotation initiated by the electromotor (1 1 ) over the axles (3) so that when the electromotor (1 1 ) rotates the axles further from the central position, the hydrofoils (1 ) are thus rotated further more in mutually opposite directions. Hydrofoils (1 ) are detached from the vessel under the water and connected to the vessel via the beams (2) and the rotation of axles (3) which allow for the rotation of hydrofoils (1 ) in opposite directions and thus regulate the vessel list. In addition to the electromotor, the vertical axle (3) can also be operated manually.
Figure 9 gives an overview of a hydrofoil-based vessel stabilisation system operated by two electromotors, and that system consists of hydrofoils (1 ) placed at a distance from the vessel under the water and connected to the vessel by a beam (2) which allows for the rotation, operated via the control levers (4) with two separate electromotors (1 1 ), each of the electromotors (1 1 ) powering one hydrofoil (1 ), exchanging data via the control device (15) on the basis of which the electromotor (1 1) operation is regulated in a way that the vessel list is regulated by moving the control levers (4) and the hydrofoils (1 ). Hydrofoils (1 ) under the water are detached from the vessel and connected to the beams (2) in a way which enables their rotation operated by two electromotors (1 1 ), each for one hydrofoil (1 ), which regulate the vessel list by rotating the hydrofoils (1 ).
