Description
Intermittierendes Wasserrückstoßtriebwerk Die Erfindung bezieht sich auf ein intermittierendes Wasserrückstoßtriebwerk. Es sind bereits Wasserrückstoßtriebwerke bekannt, bei denen die aus einer Brennkammer mit einer nachgeschalteten Lavaldüse expandierten Gase das Wasser beschleunigen.Intermittent Water Recoil Engine The invention relates to on an intermittent water recoil engine. They are already water recoil engines known, which consist of a combustion chamber with a downstream Laval nozzle expanded gases accelerate the water.
Die vorliegende Erfindung bezieht sich auf eine vorteilhafte Weiterbildung derartiger, mit einer Lavaldüse ausgestatteten Wasserrückstoßtriebwerke, die dadurch gekennzeichnet ist, daß der Brennkammer ein diese konzentrisch umgebendes beidseitig offenes Wasserführungsrohr zugeordnet ist, das sich zu einem der Lavaldüse mit Abstand nachgeschalteten Drosselkegel verjüngt und daß ein mit dem Wasserführungsrohr verbundenes Wasserausstoßrohr vorgesehen ist, dessen Durchmesser größer ist als der der Drosselkegelmündung.The present invention relates to an advantageous further development such, with a Laval nozzle equipped water recoil thrusters that thereby is characterized in that the combustion chamber has a concentrically surrounding it on both sides open water pipe is assigned, which is to one of the Laval nozzle with a distance downstream throttle cone tapers and that a connected to the water pipe Water discharge pipe is provided, the diameter of which is larger than that of the throttle cone mouth.
Die erfindungsgemäße Anordnung des sich zu einem Drosselkegel verjüngenden Wasserführungsrohres und des mit diesem verbundenen Wasserausstoßrohres hat den Zweck, eine Abstützung der aus der Lavaldüse gerichtet austretenden expandierenden Treibgase zu schaffen, um zu verhindern, daß diese in der Fahrtrichtung zur Wirkung kommen. Hierdurch wird erreicht, daß die austretenden expandierenden Gase in vollem Umfange zum Ausstoßen des Wasserkolbens aus dem Wasserausstoßrohr zur Auswirkung kommen.The inventive arrangement of the tapering to a throttle cone Water guide pipe and the water discharge pipe connected to it has the Purpose of supporting the expanding direction exiting the Laval nozzle To create propellant gases to prevent them from taking effect in the direction of travel come. This ensures that the exiting expanding gases are in full Amount for ejecting the water piston from the water ejection tube to impact come.
Um ein Füllen des Wasserausstoßrohres nach jeder erfolgten Expansion zu gewährleisten, ist in weiterer Ausbildung der Erfindung der Drosselkegel in einer solchen Entfernung von der Mündung der Lavaldüse angeordnet, daß ein ausreichender Füllquerschnitt gegeben ist.To fill the water discharge tube after each expansion to ensure is in a further embodiment of the invention, the throttle cone in one such a distance from the mouth of the Laval nozzle that a sufficient Filling cross-section is given.
Um ein ungestörtes Ausströmen der expandierenden Treibgase aus der Mündung der Lavaldüse zu gewährleisten, ist in weiterer Ausbildung der Erfindung der Querschnitt der Drosselkegelmündung gleich oder größer- als der Querschnitt der Mündung der Lavaldüse.In order to ensure an undisturbed flow of the expanding propellant gases from the To ensure the mouth of the Laval nozzle is a further development of the invention the cross section of the orifice of the throttle cone is equal to or greater than the cross section the mouth of the Laval nozzle.
Die Zeichnung zeigt eine beispielsweise Ausführungsform der Erfindung.The drawing shows an exemplary embodiment of the invention.
Die Brennkammer 1 ist koaxial an dem vorderen Ende eines beidseitig offenen Wasserführungsrohres 8 angeordnet. Die Brennkammer ist mit einer Lavaldüse 6 versehen und über die Rippe 3 mit dem Wasserführungsrohr 8 verbunden. Die Speisung der Brennkammer 1 erfolgt über die Leitungen 4 und 5. Das Wasserführungsrohr 8 endet in einem sich verjüngenden Kegel ?. Mit dem Drosselkegel ? ist das Wasserausstoßrohr 2 verbunden, dessen Durchmesser größer ist als der Durchmesser der Mündung des Drosselkegels 7. Die sich verjüngende Wandung des Drosselkegels 7 bildet eine an dem Wasserausstoßrohr 2 liegende Abstützfläche für die aus der Mündung der Lavaldüse 6 austretenden und gerichtet durch die Mündung des Drosselkegels in- das Wasserausflußrohr einströmenden Treibgase. Zur Aufnahme des Schubes bzw. der Reaktionskräfte stützen sich die Gase an dem konischen Außenmantel des Drosselkegels 7 ab. Nach Beendigung des Ausstoßvorganges wiederholt sich der Prozeß, wobei die Füllung des Wasserausstoßrohres 2 durch das vorderseitig offene Wasserführungsrohr 8 erfolgt. Hierbei ist der zwischen der Lavaldüse 6 und dem Mantel des Drosselkegels 7 bestehende Querschnitt so bemessen, daß eine zuverlässige Füllung des Wasserausstoßrohres 2 nach jeder Expansion gewährleistet ist.The combustion chamber 1 is arranged coaxially at the front end of a water guide pipe 8 which is open on both sides. The combustion chamber is provided with a Laval nozzle 6 and connected to the water guide pipe 8 via the rib 3. The combustion chamber 1 is fed via lines 4 and 5. The water guide pipe 8 ends in a tapering cone? With the throttle cone? The water discharge pipe 2 is connected, the diameter of which is larger than the diameter of the mouth of the throttle cone 7. The tapering wall of the throttle cone 7 forms a support surface on the water discharge pipe 2 for the exiting from the mouth of the Laval nozzle 6 and directed through the mouth of the throttle cone propellant gases flowing into the water outlet pipe. To absorb the thrust or the reaction forces, the gases are supported on the conical outer surface of the throttle cone 7. After completion of the ejection process, the process is repeated, the water ejection tube 2 being filled through the water guide tube 8 which is open at the front. In this case, the cross section existing between the Laval nozzle 6 and the jacket of the throttle cone 7 is dimensioned so that reliable filling of the water discharge tube 2 is ensured after each expansion.
