Problems solved by technology

[0006] Due to the formation of a Karman vortex street, on the one hand, the efficiency of the work of the hydrofoil is decreasing, that is, in the case of a rudder, the rudder force decreases

Embodiment Construction

[0051] In the various embodiments of the invention described below, the same components are provided with the same reference numerals.

[0052] figure 1 A perspective view of hydrofoil 100 is shown. In this case, the hydrofoil 100 consists of a fishtail shape or shilling (Schilling ) shape of the rudder formed. The rudder comprises a leading edge 10 and a trailing edge 20 . Side 11 extends between leading edge 10 and trailing edge 20 . End plates 14 are arranged in each case at the upper end 12 and at the lower end 13 of the hydrofoil 100 . Since the present hydrofoil 100 takes the form of a fishtail-shaped rudder, the end 15 of the rudder widens from the rear region 16 forming the narrowest point of the rudder to the trailing edge 20 . A total of five projections 30 designed as plate-shaped ribs are arranged on the trailing edge 20 , which in each case extend from the upper end 12 to the lower end 13 and are arranged parallel to one another.

Abstract

The airfoil (100) has five projection bodies (30) that are designed as plate-like ribs and provided at an end strip (20). Each projection body extends 75 percentage over the entire length of the end strip parallel to a center line of the airfoil or along the center line in a cross-section of the airfoil. The projection body orthogonally protrudes from a surface of the end strip. The breadth of the projection body corresponds to the half of the width of the end strip. The end strip runs in a straight-line, convex or concave.

Description

technical field [0001] The invention relates to a hydrofoil with a trailing edge, in particular a rudder, for water vehicles, especially ships. Background technique [0002] In the current context, a hydrofoil is a device used and / or installed in a watercraft that produces buoyancy in the field of hydrodynamics. Examples of hydrofoils are rudders on hydrofoil boats, spines, hydrofoil skids (Tragflügelkufen), stabilizer fins or other fin-shaped bodies of water vehicles. The hydrofoil according to the invention is especially suitable for use as a rudder, where it is also possible to use it for one of the above-mentioned bodies, or for another body of the hydrofoil type. [0003] Hydrofoils of the known art generally have a leading edge arranged in the direction of flow or aligned in the direction of travel of the watercraft, and a trailing edge opposite said leading edge. The sides or walls of the foil are disposed between the leading edge and the trailing edge. The upper e...
