Abstract

Offenbart ist ein leichtes Tragflächenboot mit mindestens einem Auftriebskörper, der ein antriebsloses Treiben des Tragflächenboots auf einer Wasserfläche ermöglicht, mit einem Antrieb, mittels dessen das Tragflächenboot auf der Wasserfläche in einer Fahrtrichtung (2) antreibbar ist und mit mindestens einer Tragfläche (10), die bei einer Fahrt des Tragflächenboots in der Fahrtrichtung (2) auf der Wasserfläche eine das Tragflächenboot in einer Vertikalen (18) anhebende Auftriebskraft erzeugt, wobei ausgehend von einer die Tragfläche (10) in der Fahrtrichtung (2) vorn begrenzenden Anströmkante (21) entlang der Tragfläche (10) strömendes Wasser relativ zu dem Tragflächenboot nach unten abgelenkt wird.Disclosed is a light hydrofoil with at least one buoyancy body, which allows a non-powered floating of the hydrofoil on a water surface, with a drive by means of which the hydrofoil on the water surface in a direction of travel (2) is drivable and at least one supporting surface (10) when the hydrofoil is driven in the direction of travel (2) on the water surface, a buoyancy force lifting the hydrofoil in a vertical (18) is generated, starting from a leading edge (21) bounding the airfoil (2) in the direction of travel (2) Supporting surface (10) flowing water is deflected relative to the hydrofoil down.

Um eine Anpassung der Tragfläche (10) an die Geschwindigkeit eines leichten Tragflächenboots zu ermöglichen wird erfindungsgemäß vorgeschlagen, dass die Tragfläche (10) in der Fahrtrichtung (2) eine im Wesentlichen konstante Dicke aufweist und dass eine die Tragfläche (10) in der Fahrtrichtung (2) hinten begrenzende Hinterkante (22) gegenüber der Anströmkante (21) in der Vertikalen (18) verstellbar ist.

Figure imgaf001
In order to enable an adaptation of the support surface (10) to the speed of a light hydrofoil, the invention proposes that the support surface (10) has a substantially constant thickness in the direction of travel (2) and that the support surface (10) in the direction of travel (FIG. 2) rear limiting edge (22) relative to the leading edge (21) in the vertical (18) is adjustable.
