DE10357309A1 - Ship or boat propulsion pipe for driving a vessel using a reaction force has a pressurized water jet for accelerating water in the pipe and creating a reaction force for propelling the vessel - Google Patents

Abstract

Propulsion pipe (1) for a ship or boat is completely immersed in the water and expels a pressurized water flow that has an annular or central shape. The pressurized water flow accelerated water already in the pipe and propels a vessel due to its reaction force mechanism.

Description

The torque tube ( 1 ) is a device for generating thrust for propulsion of ships and is basically an alternative to the propeller.

The torque tube ( 1 ) based on the reaction principle, wherein pressurized water as a propellant, a submerged tube ( 1 ) flows through centrally and thereby entraining a multiple of the pressure water flow from the surrounding water s. 1 ,

Alternatively, the pressurized water on the inner shell of the torque tube ( 1 ) via an annular gap ( 2 ) are fed and sucked through the circumferentially perforated outer jacket. S. 2

The Principle is state of the art and is used in many ways to promote liquids and bulk materials used.

When Propellants are usually water, steam or air.

To on suggestions the company Körting for use as a transverse thruster is a comparable use as ship propulsion so far not known.

The pressurized water is pumped ( 3 ) (Preferably a self-priming centrifugal pump) or a pump / motor - unit generated.

The Thrust control should largely by throttling the motive water flow take place, the drive motor as evenly as possible in the most economical Speed range is driven.

The suction tube ( 4 ) is to be placed so that the suction of air is safely prevented even in rough seas.

The suction flow should be via filters ( 5 ) are guided in order to keep away from the pump, especially with flat water entrained stones or flotsam. S. 3 ,

The pressurized water can be distributed via distributor ( 6 ), so that other consumers such as extinguishing pipes can be operated via branches s. 3

The pressurized water flow is directed to two thrust pipes ( 1 ), by partial throttling of the pressurized water produced in each case the Bb.- or Stb.- push tube ( 1 ) a different force and thus allows maneuvering.

In addition, in the front section of the ship transverse thrust pipes attached to the Körting system become.

All push tubes ( 1 ) can be used by the main pump ( 3 ) are supplied. S. 3 ,

The reverse drive is achieved by retracting deflection surfaces ( 7 ) in the thrust-water flow causes. S. 4 ,

When used as an outboard drive are the suction tube ( 4 ) and the pressure tube ( 8th ) vertically one behind the other and are firmly connected.

Suction tube ( 4 ) and pressure tube ( 8th ) form the shaft of the outboard drive via the in the torque tube ( 1 ) is transmitted to the hull of the vehicle.

By positioning the suction tube ( 4 ) in front of the 90 ° angled pressure pipe ( 8th ) and cladding both tubes with a streamlined shaped baffle creates a carrier ( 9 ), at the lower end of which the torque tube ( 1 ) is firmly attached. S. 5 ,

At the rear end of the carrier is a retractable half tube ( 7 ), that in the folded state, the outlet of the torque tube ( 1 ), wherein the liquid flow deflects by 180 ° and so reverse thrust is generated.

The carrier is replaced with a commercially available device ( 10 ) attached to the hull to be driven.

Pressure tube ( 8th ) and suction tube ( 4 ) end in the upper area in staggered pipe fittings, which are connected via pipe or hose lines with the pump ( 3 ) or the distributor ( 6 ) are connected.

Advantages:

• 1. Geringe Gefahr der Zerstörung bzw. Beeinträchtigung des Haupantriebes durch treibende Gegenstände oder bei Grundberührung.
• 2. Keine Gefahr der Verletzung von Schwimmern durch drehende Teile.
• 3. Universelle Nutzung der Antriebsmaschine u. a. als Lenz- oder Feuerlöschpumpe.
• 4. Einfache bzw. preiswerte Bauweise durch Entfall von Getrieben und Wellenanlagen zugunsten von Standardteilen ( Rohrleitungen und Absperr- bzw. Drosselarmaturen).
• 5. Bessere Massenverteilung durch weitgehend freie Wahl des Standortes der Haupt-Maschinen
• 6. Verbessertes Strömungsverhalten.
• 7. Entfall der Ruderanlage bei ausschließlicher Steuerung durch Schubvektoren.
• 8. Schnellere Reaktionsfähigkeit bei Notmanövern (voll Voraus auf voll Zurück innerhalb von Sekunden ohne Umsteuerung der Hauptmaschine).
• 9. Einfachere preiswertere Bauweise der Hauptmaschinen (keine Umsteuerung keine Getriebe).
• 10. Kompakte Bauweise – Gewichtseinsparung.

Unlike the propeller drive, no moving parts are arranged in the water flow of a torque tube, resulting in the following advantages:

• 1. Low risk of destruction or impairment of the main drive by driving objects or ground contact.
• 2. No risk of floats being injured by rotating parts.
• 3. Universal use of the prime mover as a bilge or fire pump.
• 4. Simple or inexpensive design by eliminating gearboxes and shaft systems in favor of standard parts (piping and shut-off or throttle valves).
• 5. Better mass distribution by largely free choice of the location of the main machines
• 6. Improved flow behavior.
• 7. Abandonment of the steering gear with exclusive control by thrust vectors.
• 8. Faster response in emergency maneuvers (full advance to full back within seconds without reversing the main engine).
• 9. Easier cheaper construction of the main engines (no reversal no gear).
• 10. Compact design - weight saving.
