Abstract

The hydrofoil arrangement for watercraft has the foils, basically conventional, mounted on hollow struts clear of the hull, and capable of pivoting about a horizontal transverse axis. Foil angle is controlled by a float (4) on a lever-arm (2d) via a rod- and/or cable linkage (2a,b,c) run inside the strut. A stop (5) limits foil-tilt upwards. From the lever-arm pivot (3) onwards, the mechanical controls may be replaced by electrical controls.

Description

Beschreibungdescription

Wasserfahrzeuge werden durch Tragflügel und damit durch Herausheben aus dem jVser schneller gemacht. Nachstehend wird eine "durch Schwimmer regelbare Tragflachenkonstruktion für Wasserfahrzeuge" beschrieben und teilweise zum Gegenstand der Patentanmeldung gemacht. Zeichnung 1 gibt die Gesamtanordnung unter dem Schiffsrumpf an, a) in Seiten-, b) in Unter-und c) in Heckansicht wieder. WL 1 ist die Wasseroberflache in eingetauchtem, WL 2 in bei Fahrt herausgehobenem Zustand des Schiffes. Die Zahl der Tragflächen ist von untergeordneter Bedeutung für das Patent.Watercraft are made by hydrofoils and thus by lifting them out made faster out of the jVser. The following is a "float-adjustable Wing construction for watercraft "described and partly related to the subject made of the patent application. Drawing 1 gives the overall arrangement under the ship's hull on, a) in side, b) in bottom and c) in rear view again. WL 1 is the water surface when the ship is submerged, WL 2 when it is lifted out during travel. The number the wing is of minor importance to the patent.

Gezeichnet sind vorn 1 hinten 2, sie können auch vorn oder hinten verschieden in Form oder Grösse sein.The front 1 back 2 are drawn, they can also be front or back be different in shape or size.

Beschrieben wird eine Tragflügelkonstruktion für Wasserfahrzeuge, bei der die in ihrer Form bekannten Tragflügel an der achse 1 horizontal gelagert sind. (Zeichnung 2).A hydrofoil construction for watercraft is described, in which the aerofoil, which is known in its shape, is mounted horizontally on the axis 1 are. (Drawing 2).

Mit der Drehung ändert sich in der ist Fahrtrichtung der Auftrieb im Wasser. Etwaige Rückwärtsfahrten sind unbedeutend, da sie nur mit geringer Geschwindigkeit erfolgen. Der Tragilugei ist in einigem Abstand vom Schiffsboden durch eine Hohlstütze in widerstandsgünstiger Form befestigt. Die Hohlstütze nimmt das Gestange 2a und 2b auf. Das Gestange führt vom Winkel 2b über 2c zum winkel 3 und über 2d zum Schwimmer 4.With the rotation, the lift changes in the direction of travel in the water. Any reversing is insignificant as it is only at a low speed take place. The Tragilugei is at some distance from the ship's bottom by a hollow support attached in a low-resistance form. The hollow support takes the rod 2a and 2b on. The rod leads from angle 2b via 2c to angle 3 and via 2d to the float 4th

Wenn das Fahrzeug in Ruhe oder ganz langsamer Fahrt im Wasser liegt( Q 1 ), ist der Schwimmer 4 an den Schiffsboden gepresst und der Tragflugel über das Gestänge 2a, b, c, Winkel 3, Gestänge 2d am Drehpunkt 1 in Auftriebs-Endstellung am Anschlag 5 angelegt.When the vehicle is in the water at rest or at a very slow speed ( Q 1), the float 4 is pressed against the bottom of the ship and the hydrofoil over the linkage 2a, b, c, angle 3, linkage 2d at the pivot point 1 in the lift end position applied at stop 5.

Bei schneller werdender Fahrt hebt sich durch die Schraglage des Tragflügels der Schiffsrumpf aus dem Wasser, d.h. der Schwimmer 4 langt an nach unten abzusinken und damit durch Drehung des Tragflügels den Auftrieb zu verringern. Die Anfangsstellung ist gestrichelt, die Endstellung ausgezeichnet. Je nach Geschwindigkeit pendelt sich das Zusammenspiel von Schwimmer und Tragflügel zu einer mittleren Lage ein. Der Tragflügel soll die Wasseroberfläche nicht erreichen, denn es ist bekannt, dass derartige Flügel mehr Auftrieb liefern, wenn ihre Oberseite ebenfalls vom Wasser umströmt sind. Die Anordnung des Schwimmers vor dem Tragflügel ist bei Wellengang von ausschlaggebender Bedeutung, desgleichen seine spitze, hohe Fornl, durch die er bei kleineren Wellen nicht ins Springen kommt.As the speed increases, the wing lifts itself up due to the inclined position of the wing the hull out of the water, i.e. the float 4 begins to sink downwards and thus to reduce the lift by rotating the wing. The starting position is dashed, the end position is marked. Commutes depending on the speed the interplay of swimmers and hydrofoils creates a middle position. The wing should not reach the surface of the water because it is known that such wings provide more lift when their top is also away from the water are flowed around. The position of the float in front of the wing is in swell of decisive importance, likewise its pointed, high shape, through which it doesn't jump in smaller waves.
