Abstract

The device which automatically counteracts the tendency of a yacht to heel over under the force of the wind. The yacht is fitted witha keel (1) with a rectangular opening (2) and flaps (3) which. can be rotated about vertical axes which are fitted in these openings. The spindles of the flaps are connected to a leverr which has a weight fitted to its outer end. When the yacht heels over this weight causes the lever to rotate and actuate the flaps. The flaps are then inclined to the plane of the keel and the flow of water over the keel exerts a force on the flaps which tends to restore the yacht to the upright position. USE - Yacht with keel designed to resist heeling action in wind.

Description

Der Erfindung liegt die Idee zugrunde, daß bei zu starker Krängung ein zu großer Verlust an Segelfläche auftritt. Sicher kann durch Raffen ein Kompromiß erreicht werden, jedoch ist bei stufenweisem Raffen eine optimale Ausnutzung der maximal möglichen Segelfläche nicht gegeben. Durch später beschriebene Erfindung ist bei gleicher Windstärke ein "aufrechteres" Segeln möglich (Voraussetzung ist natürlich ausreichende Qualität der Segel). Nicht zuletzt ist diese Einrichtung der Sicherheit zuträglich, da im dynamischen Bereich der Stabilität ein erhebliches Aufrichtmoment zugute kommt.The invention is based on the idea that when too strong Heeling an excessive loss of sail area occurs. A compromise can surely be reached by gathering, however, with gradual gathering is an optimal use the maximum possible sail area not given. By Invention described later is at the same wind force a "more upright" sailing possible (prerequisite is sufficient sail quality, of course). Not least is this facility conducive to security because in dynamic range of stability a considerable Raising moment benefits.

Im Mittelteil des Kielschwertes sind ein oder mehrere ruderähnliche Klappen, die durch Schwerkraft betätigt werden, eingebaut. Aus hydrodynamischen Gründen wird man die Betätigungsmechanik innerhalb des Schiffskörpers anbringen. Ein Gewicht betätigt über Hebel die Kompensator­ klappen. Die Klappengröße, sowie Anzahl der Klappen wird auf den gewünschten Effekt abgestimmt sein, ebenso wird dies die Größe bzw. die Masse des Betätigungs-Gewichtes beeinflussen.In the middle part of the keel sword there are one or more rudder-like flaps operated by gravity are installed. For hydrodynamic reasons you will the actuation mechanism inside the hull attach. A weight operates the compensator via levers Valves. The flap size and number of flaps will be be tailored to the desired effect, as well this is the size or the mass of the actuation weight influence.

Wirkungsweise: Bei stärkerer Krängung betätigt das Gewicht das Gestänge bzw. die Hebel der Kompensatoren. Durch das Ausstellen der Klappen, sowie deren Wirkungsweise zuein­ ander, tritt ein, gemäß Impulssatz und Tragflügeltheorie, der Krängung entgegenwirkendes Moment auf.Mode of action: In the case of more heeling, the weight is activated the linkage or the lever of the compensators. By the Expose the flaps and their mode of operation other, occurs, according to momentum theorem and wing theory, moment counteracting the heel.

Anzahl, Anordnung der Klappen, bzw. verschiedene Varianten der Ausstellwinkel sind auf den jeweiligen Schiffstyp abzustimmen.Number, arrangement of the flaps, or different Variants of the opening angle are on the respective To coordinate ship type.
