DE19637838A1 - Water craft propulsion system using e.g. water jet pumps, air cushions with propellers or electrohydraulic effect - Google Patents

Abstract

The drive system uses an electrohydraulic effect in which arc discharges are provided within a dielectric fluid at a high pressure, to provide a pressure wave. The hull of the vessel has a number of open hollow cylinders (HZ) below the water level, in which arc discharges are generated via electronically controlled generators, (G), to provide pulsed pressure waves which drive the vessel forwards.

Description

This invention is in the field of water propulsion technology assign vehicles.

Modern drive systems for water vehicles usually consist of Otto or diesel engines, their forces by means of the crankshaft be transferred to a boat / ship propeller and thus ensure propulsion in the water.

There are also watercraft that have engines with Water jet pumps or as hovercraft with propellers are driven.

In addition, wind power is gaining on the world's oceans again Importance by adding electronic to the conventional drive controlled technical sails can be installed on ships.

The invention has for its object a drive system for Watercraft with high efficiency, high economy sensitivity and very low susceptibility to failure.

This object is achieved by the features of Claim resolved.

The basis of this new drive system is the electrohydraulic effect, after which in the event of spark discharges dielectric liquids high pressures can be realized. The medium fresh water is not a dielectric one Liquid, but a very bad electrical Conductor, for seawater around a poor electrical conductor or a weak electrolyte. Experiments have shown that in both media the electro-hydraulic effect with a corresponding Construction and depending on the intensity of the spark discharges is working. The principle is watercraft to build or convert so that in the below the water level lying rear section several hollow cylinders open to the rear are arranged in which electronically controlled generators Spark discharges occur due to the electrohydraulic Effectively generate pressure waves and thus the water Give the vehicle a feed.  

The hollow cylinder should be designed so that by means of a strong cross-section (on the electrodes on both sides for spark discharges with appropriate electronic control and Opening the hollow cylinder in the direction of travel also reversing thrust (braking, turning maneuver) is guaranteed.

This propulsion system could be used on all types of watercraft with little effort either at the new building or also can be used as retrofitting.

The good economic aspect should be particularly emphasized What the use of materials (due to the saving of large Masses due to the elimination of marine diesel engines, rudders and propellers) and the resulting increased payload ability concerns.

The high maneuverability (e.g. turning on the spot), the low susceptibility to faults (since propellers and the conventional steering gear can be completely eliminated) other big advantages. The generators could drive also about alternative or environmentally friendly energies (e.g. Wind power, hydrogen turbines etc.).

The technical implementation of this drive system could through experimental experiments on models (Merial use, material selection, electronic control, technical Subtleties).

In the sketch (principle) is a drive system for water vehicles shown that are based on the electro hydraulic effect.

This system consists of several in the rear and separated in cross section:
Hollow cylinder HZ
Engine / turbine M / T
Generator G
Ignition transformer ZT
Partition wall TW
