auf Verminderung des Widerstandes wirkt.acts to reduce the resistance.
Patentiert im Deutschen Reiche vom 3. November 1911 ab.Patented in the German Empire on November 3, 1911.
Bei den üblichen Segeleinrichtungen wird die Stabilität des Fahrzeugs gewöhnlich durch seine Form und durch tiefliegenden Ballast erreicht, während es andererseits bekannt ist, durch Einstellen der Segel eine nach oben gerichtete Winddruckkomponente zu erhalten, die das Fahrzeug etwas aus dem Wasser anhebt und dadurch den Widerstand vermindert, den das Fahrzeug bei seinem Bewegen durch ίο das Wasser findet. Diese bekannte Anordnung ist aber sehr verwickelt.With the usual sailing devices, the stability of the vehicle is usually through its shape and achieved by deep ballast, while on the other hand it is known to obtain an upward wind pressure component by adjusting the sails, which lifts the vehicle a little out of the water and thereby reduces the resistance, that the vehicle finds when moving through ίο the water. This known arrangement but is very involved.
Die Erfindung bezweckt nun, die gleichenThe invention now aims to do the same
Ziele mit einfacheren Mitteln zu erreichen.To achieve goals with simpler means.
Nach der Erfindung ist das Segel um eine etwa wagerecht liegende, an Masten, Stangen usw. befestigte Welle drehbar gelagert. .According to the invention, the sail is around an approximately horizontally lying, on masts, poles etc. fixed shaft rotatably mounted. .
In der Beschreibung ist als Beispiel das Großsegel eines Segelbootes gewählt worden. Fig. ι der Zeichnung stellt eine Seitenansicht so und Fig. 2 eine Hinteransicht des Bootes dar. Das Boot α ist, wie üblich, mit Mast b und Großbaum c ausgerüstet, deren Spitzen durch das Tau d miteinander verbunden sind. Zwischen Tau d und Mast b ist eine Achse e anas gebracht, an welcher das Großsegel f an den Stellen k, I drehbar befestigt ist. Das Großsegel wird durch die Stangen g, h gespannt gehalten, indem es zunächst mit der Stange g fest verbunden ist und dann bei i angezogen wird. Die unterhalb*der Achsee befindliche Segelfläche wird zweckmäßig größer gewählt als die oberhalb.In the description, the main sail of a sailing boat has been chosen as an example. Fig. 1 of the drawing shows a side view and Fig. 2 shows a rear view of the boat. The boat α is, as usual, equipped with mast b and boom c , the tips of which are connected to one another by the rope d. An axis e anas is brought between the rope d and the mast b , to which the mainsail f is rotatably attached at the points k, I. The mainsail is kept taut by the rods g, h by first being firmly connected to the rod g and then being tightened at i. The sail area located below * the Achsee is expediently larger than that above.
Bei einem von links, senkrecht zur· Segelfläche einsetzenden Winddruck, den man sich im Flächenschwerpunkt m angreifend denken kann (Fig. 2), weicht die unterhalb der Achse e befindliche Segelfläche nach rechts aus, und das Segel nimmt etwa die gestrichelt gezeichnete Lage f ein. Der Schwerpunkt m wandert dabei nach ml', und der horizontal gerichtete Winddruck η läßt sich in eine senkrecht zur Segelfläche f gerichtete Komponente 0 und in eine parallel zu f verlaufende Komponente p zerlegen, die auf das Segel keinen Druck ausübt, so daß nur die Kornponente 0 wirksam ist. Diese ist schräg nach oben gerichtet und kann daher in eine wagerechte Komponente q und eine senkrechte Komponenter zerlegt werden, die einem Oberneigen des Bootes entgegenwirkt und 5» daher die Stabilität erhöht. Gleichzeitig wird der Reibungswiderstand des Bootes im Wasser in bekannter Weise vermindert, indem ein Teil des Bootsgewichtes durch die Komponente r aufgehoben wird.In the case of a wind pressure starting from the left, perpendicular to the sail area, which can be thought of as attacking the area centroid m (Fig. 2), the sail area located below the axis e deviates to the right, and the sail assumes approximately the position f shown in dashed lines . The center of gravity m moves to ml ', and the horizontally directed wind pressure η can be broken down into a component 0 directed perpendicular to the sail area f and a component p running parallel to f , which exerts no pressure on the sail, so that only the components 0 is effective. This is directed obliquely upwards and can therefore be broken down into a horizontal component q and a vertical component, which counteracts the boat leaning over and therefore increases stability. At the same time, the frictional resistance of the boat in the water is reduced in a known manner in that part of the boat's weight is offset by component r .
Außer der beschriebenen sind auch andere Ausführungsformen denkbar. Man kann z. B. die Achse e fortlassen und das Segel an Mast b und Tau d an den Stellen k, I durch Taue befestigen, die gleichfalls eine Drehung um die durch die Befestigungspunkte gegebene Achse zulassen. Ferner kann auch der Stützpunkt bei k fortfallen, wenn mit der Stange g bei / etwa ein genügend langer Zapfen starr verbunden ist, der in einem am 65 Mast b befestigten Lager ruht. In allen Fällen "In addition to the one described, other embodiments are also conceivable. You can z. B. omit the axis e and attach the sail to mast b and rope d at points k, I with ropes that also allow a rotation about the axis given by the attachment points. Furthermore, the support point at k can also be omitted if a sufficiently long pin is rigidly connected to the rod g at /, which rests in a bearing attached to the mast b. In all cases "
ist das Segel durch geeignete Vorrichtungen gespannt zu halten, damit auch bei schräger
Lage desselben alle üblichen Segelmanöver ausgeführt werden können.
"the sail must be kept taut using suitable devices so that all common sailing maneuvers can be carried out even when it is in an inclined position.
