摘要： The present invention relates to an apparatus for the stabilizing of the direction of travel of watercraft. The invention relates specifically to a sword or fin for sailboards. In order to allow the wind-profile like shape of the apparatus to adjust itself in accordance with a prevailing velocity of flow or a prevailing flow thereagainst, the apparatus comprises two deformable side walls which are mounted to a rigid and stiff center wall exclusively at an area located at the leading edge thereof in relation to the direction of flow. These side walls enclose together with the two oppositely arranged surfaces of the center wall two void spaces. Depending on the prevailing pressure situations between the luff side and the leeward side, an optimal hydrodynamic flow profile is automatically generated. According to preferred embodiments, the trailing edge of the apparatus comprises vacuum pumps which communicate with the void spaces, which vacuum pumps are present in form of water jet pumps. This allows additionally a controlling of the profile corresponding and in dependence from the velocity of flow.

摘要： The invention relates to a hydrofoil arrangement for a hydrofoil craft with at least one fully submerged lifting wing. The hydrofoil arrangement includes at least two struts pivotally arranged on the hydrofoil craft with each strut being connected to a lifting wing. The struts are arranged with their centers of effort of hydrodynamic forces behind the pivot axes of the struts during forward travel of the hydrofoil craft. They are arranged to pivot relative to the hydrofoil craft when the hydrofoil craft experiences a disturbance in roll-angle. This results in a transversal movement of the hydrofoil craft relative to the water surface during forward travel. The hydrofoil arrangement also increases the roll- stability for a hydrofoil craft.

摘要： A rudder of aquatic carrier is described, which includes a fixing component, a retractable component, and a first elastic component. The retractable component is pivoted to the fixing component; the first elastic component connects the fixing component and the retractable component and supports the retractable component. When the retractable component experiences an external force, the first elastic component is compressed and causes the retractable component to rotate with respect to the fixing component. When surfers or swimmers are hit by the rudder of aquatic carrier described in this invention, the rotation of the retractable component with respect to the fixing component reduces the force exerted on them, thus preventing them from being hurt. In addition, an aquatic carrier with a rudder is also described.

摘要： Water Craft or amphibious vehicle, includes a hull fitted with at least one elongate longitudinal keel; which may be extruded from natural or synthetic rubber. The keel has base, and at least two dependent keel members, which in steady state conditions slant downwards to port and starboard. If the keel is grounded, keel members deform elastically upwards against the base, absorbing shock. Keel members can be pushed down by water pressure, acting as dependent keels or. This may occur when cornering, or when planing. Stops act against stops on the base, so that when keel member is pushed downwards by water pressure, it cannot be forced beyond vertically dependent position. Alternatively, discrete keels may be provided on either side of the hull.

摘要： Methods are disclosed for increasing lift and decreasing drag on hydrofoils and swim fins. These methods include providing a hydrofoil with a highly swept back leading edge portion and orienting the hydrofoil at a significantly reduced angle of attack in which the reduced angle of attack occurs at an angle that is substantially transverse to the hydrofoil's direction of movement through a surrounding fluid medium. The lee surfaces of the hydrofoil are provided with a substantially unobstructed flow path as well as a separation reducing contour so as to permit lift generating attached flow conditions to form along such lee surfaces. Substantially rigid structural reinforcement is provided to prevent the hydrofoil from deforming significantly during use. Methods are disclosed for providing a hydrofoil with a substantially longitudinal recess or venting system located substantially along the center axis of the hydrofoil. The attacking surfaces of such a hydrofoil are provided with an anhedral contour that forms a substantially lengthwise channel with the recess or venting means located along the center axis of this lengthwise channel. Methods are disclosed for applying these lift generating and drag reducing methods to both non-flexible and flexible hydrofoil blades that are used in reciprocating propulsion strokes through a fluid medium. Also provided are methods for significantly controlling and reducing the build up of torsional stress forces within a flexible hydrofoil as it is encouraged to twist to a reduced angle of attack during use.
