The invention relates to electrical engineering and can be used to create aerospace vehicles and machines and drives land transport.

There is a method of creating an electrodynamic thrust implemented in an electrodynamic propulsion (patent RU No. 2013229, IPC B60L 11/00), the essence of which is that the electric power of the AC power source is converted into thrust force by interaction of an electric current flowing in the armature, the magnetic component of the displacement current generated in the space between the tires of the inductor. Thus, the thrust force acts on the anchor, located in the magnetic gap of the inductor, and moves the vehicle in the direction of the momentum vector of forces.

The main disadvantages of this method are the small thrust force and low efficiency due to the large energy losses caused by scattering of electromagnetic process on the wave resistance of the medium between the tires of the inductor, which is the anchor.

The closest physical essence is a way of creating an electrodynamic thrust implemented in an electrodynamic propulsion (patent RU No. 2270513, IPC H02K 51/00) and adopted for the prototype. In the prototype of the electric power of the AC power source is converted into thrust by the interaction of the magnetic field in the gap MAGN is toprovide coil with an electric current in the armature, located in the magnetic gap of the inductor and mechanical contact with the magnetic core of the inductor. Due to thrust the vehicle moves in the direction of the electrodynamic vector of the force impulse.

The magnetic circuit substantially reduces the scattering of electromagnetic process, reducing power losses compared with similar, but still in the prototype provides little traction and low efficiency, which is caused by the loss of electricity on a large magnetic resistance of the medium in the gap of the magnetic circuit of the inductor, which is the anchor.

The objective of the proposed method is the reduction of energy losses, increase traction and increase efficiency.

The problem is solved by the fact that in the known method of creating an electrodynamic thrust in the direction of the momentum vector of forces, the transformation of the electric power source AC through the interaction of the magnetic field in the magnetic core of the inductor and the electric field according to the invention, allow the interaction of the magnetic induction vector of the closed magnetic circuit made of electrically conductive ferromagnetic material, orthogonal to it by the vector of the electric dipole arising in the magnetic circuit between the electrodes covering the external and internal surfaces zamknutoj the magnetic circuit.

The invention is illustrated in the drawing.

The figure shows the device, which can be implemented by the proposed method.

The device is a magnetic circuit consisting of the power source 1 of alternating current and a closed magnetic circuit 2, is made of electrically conductive ferromagnetic material, with the excitation winding 3 connected to the terminals of the DC power source 1. On the inner and outer surfaces of the magnetic core 2 are electrodes, respectively 4 and 5 in stripes, covering these surfaces. The electrodes 4, 5 are connected to terminals of an alternating voltage power source 1.

The method is as follows. Through winding 3 connected to the terminals of the DC power source 1, in the magnetic core 2 excite a magnetic field with magnetic induction vector:

V=I·w·µ/l→[V·s/m2=A·Ω·s/m2],

where I is the current in the excitation winding, A; w - number of turns in the winding; µ is the magnetic permeability of the magnetic circuit, Ohm·s/m; l is the length of the magnetic path m

Under the influence of an alternating voltage power source 1, is formed between the electrodes 4 and 5 in the conductive medium of the magnetic circuit of the electric dipoles:

qr=U·g·τ·r→[CL·m=V·s·m/W].

where U is the voltage on the electrodes;

g - conductivity is infoprovider, 1/Ohm;

τ is the pulse duration, power, s, τ=1/2f;

f is the operating frequency of the power source AC, Hz;

r - length of the electric dipole and the distance between electrodes, m;

As a result of interaction of orthogonal vectors, and q·r, changing with circular frequency (ω=2πf) of the power source 1 AC, get electrodynamic vector pulse power:

Ft=[B×q·r]→[A·Ω·s/m2×··M/W]=[N·C], which for the time interval t=1 second effect 2f times the vehicle, with this magnetic circuit, and drives the vehicle in the direction of the momentum vector of forces Ft.

When you invert the phase of one of the excitatory values of current or voltage corresponding to the vector and the momentum vector of the forces are reversed, and the vehicle starts to move in the opposite direction of the original.

Magnetic resistance conductive ferromagnetic magnetic circuit the magnetic circuit by the proposed method can be tens of times smaller than the magnetic resistance of the air or vacuum gap in the magnetic core of the inductor of the prototype, as well as the conductivity of the magnetic circuit 2 is substantially greater conductivity of the gap in mayprovide inductor prototype, which accordingly reduces the loss of electricity is energii, increase traction (vector pulse power) and increases the efficiency of the proposed method in comparison with the prototype.

The way to create an electrodynamic thrust in the direction of the momentum vector of the power conversion power source AC through the interaction of the magnetic field in the magnetic core of the inductor and the electric field, characterized in that allow the interaction of the magnetic induction vector of the closed magnetic circuit made of electrically conductive ferromagnetic material, orthogonal to it by the vector of the electric dipole arising in the magnetic circuit between the electrodes covering the external and internal surfaces of the closed magnetic circuit.
