Abstract

The air cushion watercraft operates using spent air and gas for its cushion. It comprises a boat for recreational purposes, driven by a forward-mounted air-cooled engine. Internal ducts carry the used cooling air and the exhaust gas discharged from the silencer to inverted-U shaped skegs running along the underside of the flat part of the hull, following the line of the chine. The hull between the skegs is concave, the propeller shaft extending below the skeg plane. There is a forward-facing cooling air intake. An air cooled engine of a motor-cary type radiator may be used.

Description

AbluftgleitbootExhausted planing boat

Fachgebiet: Bootsbau Die Erfindung betrifft ein Gleitboot das auf der Kühlluft und den Abgasen seines Verbrennungsmotores über das Wasser gleitet.Subject: Boat building The invention relates to a planing boat on the the cooling air and the exhaust gases of its internal combustion engine slides over the water.

Dabei wird die orhandene'tAbluftb so unter das Boot geleitet das ein Luftpolster entsteht.The existing exhaust air is then passed under the boat Air cushion is created.

Bei einem solchen Boot wird die vorhandene Energie besser ausgenutzt. Durch Verringerung der Reibung zwischen Wasser und Boot steigen die Fahrleistungen bei geringem Kraftstoffverbrauch.With such a boat, the available energy is better utilized. Driving performance increases by reducing the friction between the water and the boat with low fuel consumption.

Es ist mir nicht bekannt, das es Gleitboote oder Luftkissenboote gibt die das Luftpolster ausschließlich mit der vorhandenen Abluft, d.h. Motorgase und Kühlluft, herstellen.I am not aware of any planing boats or hovercraft which the air cushion exclusively with the existing exhaust air, i.e. engine gases and Cooling air.

Der Erfindung liegt die Aufgabe zu Grunde, die freiwerdende Energie in Form von " Abluft " zu nutzen.The invention is based on the object of the energy released to use in the form of "exhaust air".

Die Aufgabe wird Erfindungsgemäß dadurch gelost das die Eühlluft und die Abgase des Bootsantriebsmotores in zwei rechts und links am Bootsrumpf verlaufenden Kanälen geleitetwird. Die Kanäle sind nach unten offen, so das sich eine tuftschicht zwischen Boot und Wasser bildet.According to the invention, the object is achieved in that the cooling air and the exhaust gases of the boat drive motor in two running on the right and left of the boat hull Channels. The channels are open at the bottom, so that there is a layer of tuft between the boat and the water.

Ausführungsbeispiel: Ein Sport-und Freizeitboot mit einem luftgekühlten Porsche Boxermotor.Embodiment: A sports and leisure boat with an air-cooled Porsche boxer engine.

Der Motor ist vorne im Boot plaziert. Das Kühlluftgebläse überragt den Bootsrumpf und steht im Fahrtwind. Es blähst sie Buft durch die beiden Zylinderreihen wo sie in dicht abgeschlossenen tichtschächten weiter geleitet wird.Hier werden die Abgase des Motors hinzu geleitet. Die Abluft wird dann in die horizontalverlaufenden, nach unten offene, Kanäle geleitet, sodaß sich eine tuftschicht zwischen Boot und Wasser bildet. Das untere Ende der Stirnwand, der beiden Buftschächte bildet eine Gummiplatte, die sich den Gegebenheiten besser anpasst.(Abb. 1The engine is placed in the front of the boat. The cooling air fan towers above the boat hull and is in the airstream. Buft blows her through the two rows of cylinders where it is passed on in tightly sealed shafts the exhaust gases from the engine are added. The exhaust air is then fed into the horizontally running, canals that are open at the bottom, so that a layer of tuft is formed between the boat and the Water forms. The lower end of the front wall of the two air shafts forms one Rubber plate that adapts better to the circumstances (Fig. 1
