DE102007034594A1 - Elastic or elastically supported elements for installing below water surface in vessel, comprises component of vessel such as rudder, keel or stabilizers, where component is particularly fastener for attaching flexible elements - Google Patents

Abstract

The elastic or elastically supported elements comprise a component of a vessel such as rudder, keel or stabilizers. The component is particularly a fastener that is provided for attaching the flexible elements. The vessel is driven against relative movements of the water. The relative movements are caused by waves or swings of the vessel.

Description

It is known that most vessels are not completely calm lying in the water, but standing Movements are exposed. Dependent From the weight of the vehicle are doing considerable amounts of energy generated, z. For example, if a several thousand tons heavy oil tanker is raised by one meter and then again decreases.

at The current design of watercraft becomes this energy but not used in any way.

By the attachment of elastic, fin-like elements below the water surface Is it possible, to convert the released energy into propulsion of the vehicle. Press these elements with each movement of the vehicle water backwards and drift this like the flippers of a diver.

Depending on whether a vehicle tends to move up or down or rocking is exposed, the elements in horizontal (for up and Movements) or in vertical (for rocking movements) alignment appropriate.

• 1. Es werden speziellen Vorrichtungen an dem Fahrzeug angebracht (ähnlich den „Flügeln" eines Tragflächenbootes), an welchen die elastischen Elemente an optimaler Stelle und in optimaler Ausrichtung befestigt sind. Diese Vorrichtungen könnten im Bedarfsfall, wenn z. B. eine Kollision droht, eingeholt werden
• 2. Die elastischen Elemente werden an bestehenden Bauteilen der Fahrzeuge, wie z. B. Ruder, Kielflosse an Segelschiffen oder Stabilisatoren an Fähren, angebracht. Diese Variante beschränkt den kontruktorischen Aufwand auf ein Minimum, führt jedoch unter Umständen nicht zum optimalen Wirkungsgrad.

There are basically two options for attachment:

• 1. Special devices are attached to the vehicle (similar to the "wings" of a hydrofoil boat) to which the elastic elements are secured in optimum position and orientation, these devices could, if necessary, be in danger of collision, for example. be caught up
• 2. The elastic elements are attached to existing components of the vehicles, such. As oars, keel fin on sailing ships or stabilizers on ferries attached. This variant limits the cost of the conducive to a minimum, but may not lead to optimal efficiency.

It It should be noted that above all the attachment of the elements to the Rudder the steering movements that are constantly taking place especially in sailing ships could convert into propulsion with the simplest means.

One positive side effect of o. g. Invention is a deceleration of the Rocking movements of the vehicle and thus a reassurance of Waterfront.

The Drawings with possible Positioning of the elastic elements is available.

Claims (1)

Elastic or elastically mounted elements, which can be mounted below the water surface on all vessels, which are exposed except the own movement movements relative to the water. These relative movements can z. B. caused by swaying or rocking of the vehicle, characterized in that the elastic elements can be attached to existing components of the vehicle (eg, rudder, keel, stabilizers) or on a specially designed holder. The drawings with possible positioning of the elastic elements are available.
