Abstract

The pipe ends located in the water are flexible and movable and carry surfaces, similar to the fins of fishes. The fins are positioned crosswise and the fin pointing towards the water level, is shorter. The amplitude of the fin is limited by a spring or an abutment. The fins have rubber sections (1) which permit them to flap from side to side w.r.t. the hull (3) when the lever (2) driving the fins is reciprocated by a drive within the boat.

Description

Flossenantrieb für Wasserfahrzeuge, kombiniert mit Wasserstrahlantrieb.Fin drive for watercraft, combined with water jet propulsion.

Die Erfindung betr«-St eilell ilossenantrieb für Wasserfalirz<uge, der nur in Verlindling mit einem Wasserstrahlantrieb funktioniert.The invention concerns a part of the drive for waterfalls, which only works in Verlindling with a water jet drive.

Bekannt ist, Wasserfahrzeuge vermittels eines kontinuierlich, oder intermittierend wirkenden Wasserstrahl antriebs anzutreiben.Is known, watercraft by means of a continuous, or to drive intermittently acting water jet.

Bekannt ist ferner, Wasserfahrzeuge mit Hilfe von Flossen, die über mechanische oder hydraulische Verbindung zum Motor bewegt werden, zu fahren.It is also known, watercraft with the help of fins that over mechanical or hydraulic connection to the engine are moved to drive.

Die letztgenannte Antriebsart hat zwar einen guten Wirkungsgrad, ist aber - wegen der komplizierten Mechanik - teuer, störanfällig und wartungsaufwendig.The latter type of drive has a good degree of efficiency, is but - because of the complicated mechanics - expensive, prone to failure and maintenance-intensive.

Die vorliegene Erfindung soll nun den Strahl antrieb mit dem Flossen antrieb kombinieren, wodurch der Gesamtwirkungsgrad erhöht werden soll.The present invention is now to propel the jet with the fins Combine drive, whereby the overall efficiency should be increased.

Diese Kombination gestattet es, den mechanischen Teil des Antriebs wegfallen zu lassen.This combination allows the mechanical part of the drive to be omitted.

Die Aufgabe wird dadurch gelöst, daß der ausstoßende oder pulsierende Wasserstrahl eines Strahlantriebs durch die flexibel oder starr ge= staltete Flosse strömt, wodurch diese (in Grenzen) bewegt wird.The object is achieved in that the ejecting or pulsating Jet of water from a jet propulsion system through the flexible or rigid fin flows, whereby it is moved (within limits).

Wasserstrahlantriebe des Fulsationsprinzips, bei dem also das Wasser hinten ausgestoßen und angesaugt wird, eignen sich besonders für diesen Vorschlag. Im Versuch wurde nämlich festgestellt, daß flexible Rohrenden eines Pulsoantriebs kräftig vibrieren. Wenn diese Rohrenden flossenförmig gestaltet sind, können Vibrationen aber in Vortrieb um= gewandelt werden; eine Kraft, die ohne zusätzliche Energie zustandekomat.Water jet propulsion of the fulsation principle, in which the water ejected and sucked in at the rear are particularly suitable for this proposal. In the experiment it was found that flexible tube ends of a pulso drive vibrate vigorously. If these pipe ends are designed in the shape of fins, vibrations can occur but to be converted into propulsion; a force that without additional energy status komat.

Die Gestaltung des zusätzlichen Flossenantriebs kann auf verschiedene Weise erfolgen.The design of the additional fin drive can be different Way.

So kann das Rohrende einfach in genügender Länge, flexibel und flossen= förmig gestaltet sein, Oder: das Rohrende (bzw. die Enden) ist aus starrem Materials aber, an geeigneter Stelle, gelenkig befestigt.So the pipe end can easily be of sufficient length, flexible and flowing = be shaped, or: the pipe end (or the ends) is made of rigid material but, at a suitable point, articulated.

Die Flossen können verschiedene Gestalt haben. Sie können z B. auch kreuzförmig sein, wobei das zum Wasserspiegel zeigende Ende kürzer sein kann.The fins can have different shapes. For example, you can also be cross-shaped, whereby the end facing the water level can be shorter.

Die Schemazeichnungen zeigen Einzelheiten und Merkmale.The schematic drawings show details and features.

Fig, i zeigt die Flosse (i) aus flexiblem Material aut dem starren Rohrende (2) steckend. (3) ist der Heckabschluß des Schiffes.Fig, i shows the fin (i) made of flexible material on the rigid Tube end (2) stuck. (3) is the stern of the ship.

Die Flossenflächen (4) versteifen gleichzeitig den Flossen= körper gegen seitliche Bewegungen. Die Flosse kann stich also praktisch nur auf und ab bewegen. The fin surfaces (4) also stiffen the fin body against lateral movements. The fin can practically only stab up and down move.

Fig 2 zeigt die Flosse (i) um 900 verdreht. In dieser Anordnung kann sie nur seitliche Ausschläge machen.Fig. 2 shows the fin (i) rotated by 900. In this arrangement can they only make lateral deflections.

Fig. 3 stellt eine Flosse (1) dar, die für zwei Abstoßrohre (2) zu= ständig ist. Der Austritt für die Wasserstrahle am Flosseninde kann übrigens auch düsenförmig gestaltet sein. Es ist denkbar, daß öine Flosee noch mehr Abstoßrohre aufnimmt.Fig. 3 shows a fin (1), which for two push tubes (2) to = is constantly. The exit for the water jets at the fin cortex can also be used be designed nozzle-shaped. It is conceivable that a floe has even more push-off tubes records.

Fig. 4 endlich läßt erkennen, daß das Prinzip auch mit einer starren Anlage durchführbar ist. Dann ist allerdings ein Gelenk (5) not= wendig. Die Flosse (i) ist hier hochgestellt, es sind daher nur seitliche Ausschläge möglich. Die Widerlager (6) begrenzen den Ausschlag. Statt Widerlager könnte man auch Federn (Gummibänder) vorsehen.Fig. 4 finally shows that the principle is also rigid Plant is feasible. Then, however, a joint (5) is necessary. The fin (i) is superscripted here, so only lateral deflections are possible. The abutments (6) limit the rash. Instead of abutments, you could also use springs (rubber bands) provide.
