The alleged invention relates to engines operating on the electromagnetic effect of creating a reactive force which provides for the movement of the vessel.

Known for the propulsion of ships and submarines, the design of which implements the influence of electric and magnetic fields in the environment movement and contains the electrodes and the electric magnets (RF patent No. 2280587, VN 11/04, 11/02, U.S. patent No. 6333444, VN 11/00, JP No. 5330487), while on the surface of the moving body are mutually perpendicular electric and magnetic fields. The electric field provided by the electrodes, electrically connected with water and placed on a circle on the surface of the body in the plane perpendicular to the direction of motion and the magnetic field of magnets located inside or outside of the body.

The design of these engines allow the use of sea water in which the vessel moves, as a working medium, which is moved relative to the vessel under the action of the Lorentz force in the direction opposite to the movement of the vessel (Handbook on the physics Chukling, "World", 1982, s-349).

The closest technical solution to the proposed propulsion is electromagnetic propulsion in seawater (RF application No. 2006140754, VN 11/00, a positive decision from 06.12.2007,), comprising a housing with a channel for the inlet and outlet of the water in which the om, the main electrodes to generate a current in an electric field, covering a section of the specified channel, and device for generating a magnetic field, oriented perpendicular to the electric field, to create a basic Lorentz force, while in the working channel have at least one pair of additional electrodes that are isolated from the main electrodes to provide electrical breakdown of water and create additional Lorentz force, coinciding in direction with the principal.

Based on the simultaneous action of an electric field generated by the main electrodes, an electric field generated by the additional electrodes and magnetic fields arise unidirectional primary and secondary Lorentz forces, which provide buoyancy of sea water in the direction opposite to the thrust force of the vessel.

However, because of the very small radius of the air tube in the breakdown of the water column in the channel, almost instantaneous discharge of the energy storage unit via the auxiliary electrodes, starting immediately after the discharge process of recombination of ions in the air "tube", which lasts a short time, as well as the demolition of the air "tube" on the channel at a rate greater than the rate of flow of water in the working channel, the conductivity of the water, and therefore, the efficiency of the propulsion remain low.

Technical results which is to increase the efficiency of the proposed propulsion due to artificially improve the conductivity of the water. This result is achieved by the fact that in the electromagnetic propulsion device, comprising a housing with a channel for the inlet and outlet of water, in which the main electrodes to generate a current in an electric field, covering a section of the specified channel, and device for generating a magnetic field, oriented perpendicular to the electric field, to create a basic Lorentz force. In addition, the working channel is set, at least one pair of additional electrodes that are isolated from the main electrodes, with the possibility of electrical breakdown of water and create additional Lorentz force, coinciding in direction with the main. According to the invention in the composition of the thruster includes a set of energy storage and switching device for providing connection of energy storage to the additional electrodes in sequence and with a frequency that is determined by the operating mode of propulsion.

The set of energy storage and devices connect to the secondary electrodes allow to increase the conductivity of the water, resulting in an increasing Lorentz force acting on the working volume of the water and, eventually, increases the efficiency of propulsion.

The drawing shows the proposed propulsion system which includes a housing 1 with a working channel for passage of water (direction d is to achieve arrow).

In the working channel are the main electrodes 2, which are, for example, flat plate, the long side of which is directed along the working channel. Additional electrodes 3 in the form of pointed pins are isolated from the main electrodes and are located in one plane along the working channel. Directions of the electric fields of the main and additional electrodes are the same. Also in the channel are devices generating a magnetic field 4 is isolated from contact with water. They represent, for example, the magnetic dipole of the two conducting electric current to the coils located on either side of the working channel. For General homogeneous magnetic field, covering the working channel, the magnetic field of the coils must be the same in direction. Part of the propulsion unit also includes a set of energy storage 5, representing, for example, a set of condenser batteries or superconducting inductive energy storage (SPIN), and the switching device 6, the conducting connection of energy storage to the additional electrodes in the order and with the frequency depending on the mode of propulsion.

The propeller provides thrust of the vessel in sea water as follows. Device generating a magnetic field 4 create in the working channel of a uniform magnetic field. the ri application of an electrical voltage to the main electrode 2 under the action of electric field intensity occurs the movement of Na ions and protons H toward the negatively charged electrode and the movement of ions in mainly Cl in the opposite direction. The Lorentz force acting on the charges, proportional to the speed of their movement in the water, i.e. their mobility. The mobility of the ions Na and Cl, the main hydrated ions in sea water salts, ≈ 100 times lower than the mobility of the protons H. Given the small concentration of salts in seawater, the main the Lorentz force will depend on the movement of protons, and the conductivity will be mainly proton character. When electrical breakdown of water between the additional electrode 3 occurs in the "gas tube", which along with the above charged particle creates the possibility of movement of free electrons, which move in the direction of additional positively charged electrode. The mobility of the electrodes in the gas "tube" ≈ 100 times higher than the mobility of the protons and four orders of magnitude higher than the mobility of the ions listed above. Therefore, the conductivity of the gas in the tube between the additional electrodes will be mainly electronic in nature. The associated additional Lorentz force will mainly depend on the movement of electrons.

To ensure the same orientation of the primary and secondary Lorentz force polarity, and hence the vector direction of the electric fields of the main and Supplement the sustained fashion electrodes should be the same. Therefore, the negative pole electrodes for security can be "grounded".

The breakdown of the water layer between two additional electrodes of the energy storage device almost instantly discharged and begins the process of recombination of ions in the gas pipe." To maintain conductivity in the working channel to the pair of additional electrodes connected new energy storage is a new category, and its implementation requires much less voltage, which reduces dzhoulevo loss. Such a serial connection of energy storage 5 to the additional electrodes via the switching device 6 allows to increase the value of the additional Lorentz force while reducing the overall dzhoulevo losses when current flows in the gas "pipes".

This results in the technical result - mover efficiency increases.

Electromagnetic propulsion, comprising a housing with a channel for the inlet and outlet of water, in which the main electrodes to generate a current in an electric field, covering a section of the specified channel, and device for generating a magnetic field, oriented perpendicular to the electric field, to create a basic Lorentz force in the working channel have at least one pair of attachment is sustained fashion electrodes, isolated from the main electrodes, with the possibility of electrical breakdown of water and create additional Lorentz force, coinciding in direction with the core, characterized in that the thruster includes a set of energy storage and switching device for providing connection of energy storage to the additional electrodes.
