Abstract

The invention describes a power system for the propulsion of ships. n this, following the complete combustion of the fuel in air in the combustion chamber, water is directly injected and steam generated. This serves for driving the compressor turbine and the ship.

Description

Energieanlage bzw. Triebwerk Energy system or engine

für den Düsenantrieb von Schiffen! 1. Mehrstufiger Radialverdichter mit anschliessender Brennkammer, direkter Wassereinspritzung zur Dampferzeugung und Antriebsturbine für den Verdichter und den Hilfsaggregaten. for jet propulsion of ships! 1. Multi-stage centrifugal compressor with subsequent combustion chamber, direct water injection for steam generation and drive turbine for the compressor and the auxiliary equipment.

Der überschüssige Dampf bzw. das Dampf- Rauschgasgemisch wird das Düsen zugeführt für den Schiffsantrieb. The excess steam or the steam-intoxicating gas mixture becomes that Nozzles fed for ship propulsion.

2. Um den erforderlichen Druck zu erzeugen der nötig ist um im Wasser durch die Düsen eine Wirkung zu erzielen, ist ein mehrstufiger Radialverdichter erforderlich. Wenn das nicht genügt, kann auch ein anderer Kompressor, z3. ein Schraubenverdichter nachgeschaltet werden.2. To generate the pressure required to move in the water To achieve an effect through the nozzles is a multistage centrifugal compressor necessary. If that is not enough, another compressor, z3. a screw compressor be connected downstream.

3. Durch die Wassereinspritzung wird die Masse vergrössert, (Masse Dampf plus Masse Rauch), und das Temperaturniveau herabgesetzt, welches günstiger ist für die Dtzsendurchströmung unter Wasser.3. The mass is increased by the water injection, (mass Steam plus bulk smoke), and the temperature level is reduced, whichever is more favorable is for the flow through the dozens under water.

4. Um die Rohrwandungen, die Turbine und die Düsen vor Anfressungen zu schützen, müssen die Teile beschichtet werden, zB. emalliert.4. To protect the pipe walls, the turbine and the nozzles from pitting To protect the parts must be coated, e.g. enameled.

Patentanspruch: 1. Energieanlage bzw. Triebswerk für den Düsenantrieb von Schiffen, dadnrch gekennzeichnet, dass zur Erzeugung des notwendigen Druckes ein mehrstufiger Radialverdichter, kombiniert mit Brennkammer, direkter Wassereinspritzung zur Dampferzeugung und Antriebsturbine installiert wird. Claim: 1. Energy system or engine for the jet drive of ships, marked thereby, that to generate the necessary pressure a multi-stage centrifugal compressor, combined with a combustion chamber, direct water injection for steam generation and drive turbine is installed. 2. Sollte der erforderliche Druck init Radialverdichtern alleine nicht erzeugt werden konnen, kann ein anderer Kompressor, zB. ein Schneckenkompressor nachgeschaltet werden.2. Should the required pressure not be achieved with centrifugal compressors alone can be generated, another compressor, e.g. a screw compressor be connected downstream. 3. Das Dampf Rauschgasgemisch treibt die Turbine für den Verdichter und die Hilfsaggregate an. Der überschilssige Dampf wird den Schiffsdusen zugeführt.3. The steam / noise gas mixture drives the turbine for the compressor and the auxiliary equipment. The excess steam is fed to the ship's nozzles. 4. Durch die direkte Wassereinspritsung wird das Temperatur niveau herabgesenkt und die Masse vergrbssert.4. The direct water injection increases the temperature level lowered and the mass increased. Masse Dampf plus Masse Rauch. Mass steam plus mass smoke. Um die Rohrwandungen, die Turbine und die Düsen vor Anfressungen zu schützen müssen die Teile beschichtet werden, eventuell emalliert. Around the pipe walls, the turbine and the nozzles from corrosion to protect the parts must be coated, possibly enameled.
