Abstract

The driving mechanism has a rocket engine installed in a combustion chamber of a jet engine and operated with hydrogen and oxygen. The rocket engine has a nozzle from which flame and flue gas shoots out. A turbine stage is coupled with a fan and/or ship's propeller such that a driving power is delivered. The engines are installed in a ship hull or attached outside the hull. A compressor pumps air in the chamber, where the oxygen reacts with the hydrogen, and the water is 800 times denser than the air.

Description

Bisher werden Schiffe meist durch Schiffsschrauben angetrieben. Das ermöglicht lediglich ein im Verhältnis zu Größe und Gewicht des Antriebssystems langsames Vorankommen. Vorteilhaft wäre ein kompaktes, umweltfreundliches Triebwerk mit höherer Leistungsabgabe und stärkerer Beschleunigung für bestimmte Schiffstypen und U-Boote. Die meisten U-Boote funktionieren getaucht nur über Elektromotoren, die durch riesige Akkumulatoren gespeist werden müssen (von Atom-U-Booten abgesehen). Dies ermöglicht nur eine langsame Fahrt, setzt ein häufiges Auftauchen voraus, stellt ein zusätzliches Gewicht dar und ist sehr platzraubend, was in den äußerst engen U-Booten wohl das größte Problem darstellt.So far Ships are usually powered by propellers. That only allows one in proportion to size and weight drive system slow progress. An advantage would be a compact, environmentally friendly engine with higher power output and greater acceleration for certain Ship types and submarines. Most submarines work submerged only over Electric motors powered by huge batteries have to (apart from nuclear submarines). This only allows a slow ride, sets a frequent Ahead of it, there is an additional weight and it is very space consuming, which in the extremely narrow Submarines probably the biggest problem represents.

Meine erfinderische Idee besteht darin, ein mit Wasserstoff und Sauerstoff betriebenes Raketentriebwerk in die Brennkammer eines Strahltriebwerks einzubauen und es unter Wasser zu betreiben.My inventive idea is one with hydrogen and oxygen Installed rocket engine in the combustion chamber of a jet engine and to operate it underwater.

Aus der Düse des Raketentriebwerks schießen eine Flamme und Verbrennungsgase hervor. Zudem wird das Wasser durch die starke Wärmeentwicklung verdampft und vergrößert so sein Volumen, wodurch der Druck in der gesamten Brennkammer des Triebwerks steigt. Da sich im hinteren Teil des desselben weniger „Kompressorräder" befinden als im vorderen, entweichen Wasser und Gase aus der Brennkammer nach hinten und treiben die Antriebswelle(n) an. Diese setzt/setzen den vorderen „Verdichter" in Rotation, der neues Wasser von vorne in die Brennkammer pumpt.Out the nozzle shoot the rocket engine a flame and combustion gases. In addition, the water is through the strong heat development evaporates and increases in size its volume, reducing the pressure in the entire combustion chamber of the Engine is rising. Since there are fewer "compressor wheels" in the rear of the car than in the front, water and gases escape from the combustion chamber to the rear and drive the drive shaft (s). This sets / sets the front "compressor" in rotation new water is pumped from the front into the combustion chamber.

Wenn man bei Schiffen die „Gebläsewelle" mechanisch mit einem Kompressor verbindet, kann das Triebwerk statt mit reinem Sauerstoff auch mit dem Luftsauerstoff betrieben werden. Der Kompressor pumpt die Luft in die Brennkammer des Raketentriebwerks, wo der Sauerstoff dann mit dem Wasserstoff reagiert.If in ships, the "fan shaft" mechanically with a Compressor connects, the engine can take place with pure oxygen also be operated with atmospheric oxygen. The compressor is pumping the air in the combustion chamber of the rocket engine, where the oxygen then react with the hydrogen.

Claims (1)

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Hauptanspruchs. Aufgabe ist es, Wasserfahrzeuge mit einem möglichst leistungsfähigen, kompakten und umweltfreundlichen Antriebssystem zu versehen. Stand der Technik ist es, Schiffe durch Schiffsschrauben, Schaufelräder Jetantrieb o. ä. anzutreiben. Aufgabe der Erfindung ist es, ein kompaktes außerhalb des Schiffsrumpfs installiertes, platzsparendes, leistungsstarkes und umweltschonendes Antriebssystem zu schaffen, das bisher nicht vorhanden ist. Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Hauptanspruchs gelöst. Ein mit Wasserstoff und Sauerstoff betriebenes Raketentriebwerk wird in die Brennkammer eines Strahltriebwerks eingebaut, was einen Betrieb unter Wasser ermöglicht. Die Neuartigkeit der Erfindung besteht in der Kombination von Raketen- und Strahltriebwerken für den Unterwassereinsatz. Hierdurch wird erstmals der Einsatz eines Verbrennungsantriebs unter Wasser ermöglicht, was insbesondere die Leistung von U-Booten steigern könnte. Mein Hauptanspruch ist dadurch gekennzeichnet, dass ein oder mehrere, am besten mit Wasserstoff und Sauerstoff betriebene Raketentriebwerke in die Brennkammer eines Strahltriebwerks eingebaut werden, wodurch ein Betrieb unter Wasser möglich wird. Für die Konstruktion des Unterwassertriebwerks sind verschiedene Varianten denkbar, woraus sich mehrere Nebenansprüche ergeben: 1. Anstatt des Einbaus eines Raketentriebwerks in ein Strahltriebwerk ist auch der Einsatz eines einfachen Raketentriebwerks mit dahinter liegendem Turbinensatz und der Einspritzung von Wasser in die Brennkammer zur Volumenvergrößerung und Leistungssteigerung möglich. Die Turbinenstufe(n) kann/können dann mit einem „Fan" bzw. einer Schiffsschraube oder ähnlichem gekoppelt werden und so die Antriebsleistung abgeben, was einem Turbopropantrieb bei Flugzeugen ähnelt. 2. Stall Sauerstoff und Wasserstoff können auch andere Treibstoffe verwendet werden. 3. Statt eines Raketentriebwerks können auch mehrere Raketentriebwerke an verschiedenen Positionen in das Strahltriebwerk eingebaut werden, z. B. ringförmig um die Gebläsewelle angeordnet. 4. Bei Schiffen ist auch ein Betrieb mit Luftsauerstoff möglich. 5. Das Triebwerk kann in den Schiffsrumpf eingebaut oder außerhalb des Rumpfs oder an anderen Stellen angebracht werden. 6. Statt eines Raketentriebwerks können auch mehrere Triebwerke miteinander kombiniert werden oder ein Triebwerk anderer Form, z. B. in Gestalt eines Rings oder andere raketentriebwerksähnliche Antriebe verwendet werden. 7. Weiterhin ist auch der Einsatz dieser Antriebstechnik im Modellbau zu schützen. 8. Zur evtl. nötig werdenden Kavitationsvermeidung sind die Methoden des Vorbeschleunigungsrotors mit evtl. verstellbarem Anstellwinkel sowie die des verbreiterten und am besten im Durchmesser veränderlichen Triebwerkseinlaufs ebenfalls zu schützen.The invention relates to a device according to the preamble of the main claim. The task is to provide watercraft with a powerful, compact and environmentally friendly drive system. The prior art is to propel ships by propellers, paddle wheels jet propulsion o. Ä. The object of the invention is to provide a compact installed outside the hull, space-saving, powerful and environmentally friendly drive system, which is not yet available. This object is achieved by a device having the features of the main claim. A rocket engine powered by hydrogen and oxygen is installed in the combustion chamber of a jet engine, allowing it to operate underwater. The novelty of the invention is the combination of rocket and jet engines for underwater use. This allows for the first time the use of a combustion drive under water, which in particular could increase the performance of submarines. My main claim is characterized in that one or more rocket engines, most preferably powered by hydrogen and oxygen, are installed in the combustion chamber of a jet engine, allowing underwater operation. For the construction of the underwater engine different variants are conceivable, resulting in several side claims: 1. Instead of installing a rocket engine in a jet engine and the use of a simple rocket engine with underlying turbine set and the injection of water into the combustion chamber to increase the volume and performance is possible , The turbine stage (s) can then be coupled with a "fan" or a propeller or the like, thus giving off the propulsion power, which is similar to a turboprop propulsion on airplanes 2. Stall Oxygen and hydrogen, other fuels can also be used. Instead of a rocket engine, several rocket engines can also be installed at different positions in the jet engine, eg arranged ring-shaped around the fan shaft 4. For ships, it is also possible to use oxygen from the air 5. The engine can be installed in the hull or outside the ship's hull 6. Instead of a rocket engine, it is also possible to combine several engines or use an engine of a different shape, eg in the form of a ring or other rocket engine-like propulsion systems Protect in the model construction 8. For possibly necessary we In order to prevent cavitation, the methods of the pre-acceleration rotor with possibly adjustable angle of attack as well as those of the widened and best-variable diameter engine intake must also be protected.
