Description

 The invention relates to the direct conversion of electrical energy into mechanical energy (kinetic energy of a propelled body), in particular, to the implementation of a method for electromagnetic acceleration of solids in conductive rail accelerators.

 Known rail conductive electromagnetic solid state accelerator containing insulated walls placed in the power housing and an electrical circuit formed by a pair of longitudinally spaced parallel electrodes shorted by a current armature and connected from the output of the accelerator to the power supply system [1].

 A prototype of the present invention is a rail conductive electromagnetic solid-state accelerator comprising electrical insulating walls and two inductively coupled electrical circuits formed in the power housing formed by internal and external pairs of longitudinally arranged parallel electrodes connected to independent power supply systems, the external pair of electrodes being shorted in the output part of the accelerator and connected to the power supply system [2].

 The disadvantage of this device is that the regular effective current flow in the accelerator channel is absolutely unstable. At the same time, the possibility of increasing the duration of its existence is associated with a higher level of in-channel electrical voltage at a fixed acceleration or lower magnitude of the electromagnetic force for a given value of the magnetic field in the space behind the armature, determined by the technical strength of the structure.

 The aim of the invention is to increase the speed of throwing solids.

 In FIG. 1 shows a rail conductive electromagnetic accelerator in the cross section of its output part in the short-circuit region between the electrodes of the external circuit; in FIG. 2 - electrical circuit for connecting circuits to power systems.

 Rail conductive electromagnetic solid state accelerator contains an inner pair of electrodes 1, longitudinally parallel to each other and forming with the current armature 2 the internal electric circuit of the accelerator.

 The electrodes 1 of the inner pair are electrically insulated from each other by insulating walls 3, and from the electrodes 4 of the outer pair by insulating spacers 5. The external circuit of the accelerator is formed by electrodes 4 and a jumper 6, shorting the electrodes in the output part of the accelerator. The assembly of electrodes 1 and 4 and dielectrics 3 and 5, if necessary, is insulated from the power housing 7 in which it is placed, by dielectric spacers 8. Each pair of electrodes 1 and 4 is connected to an independent power supply system, while the electrodes 4 of the external circuit are connected to the power supply system 9 from the input part of the accelerator, and the electrodes 1 of the internal circuit to their power supply system 10 from the output part of the accelerator. Neighboring electrodes of the external and internal circuits located on one side of the longitudinal axis of the accelerator are connected to the same pole of the power supply systems 9 and 10, which ensures the flow of electric currents in the opposite direction along the contours.

 The device operates as follows.

 After assembling the package of electrodes 1 and 4, dielectrics 3, 5, 8 and jumpers 6, it is placed in the power housing 7 and by moving the walls of the housing 7 or in another way create a preliminary voltage of the structure. Then, in the channel formed between the electrodes 1 of the inner circuit and the side walls 3, an accelerated body is placed - an anchor 2 or an accelerated body with an anchor 2.

Then, the electric energy stored in the power supply systems 9 and 10 is discharged into the external and internal electric circuits of the accelerator, respectively. When the current I _in flowing through the armature 2 interacts with the transverse magnetic field B _{n of the} external electrical circuit, an electromagnetic force F _em arises, accelerating the armature 2, and hence the missile body.
