Abstract

Purpose: Problem statement: the presence of a wide range of radio-electronic systems among the opposing parties creates the need to equip protected objects and mobile groups with countermeasures that solve the tasks of suppressing and disabling the electronic component base, which is part of unmanned systems, communication systems, actuators, data collection and control systems. The development of electrodynamic suppression systems based on pulsed electromagnetic radiation sources, as an alternative to kinetic suppression, involves the use of the principles of magnetocumulative generation, which explains the great interest in the synthesis of an electrodynamic model of a multi-acting magnetocumulative generator, as well as the design of an inductive element and methods for controlled change of effective magnetic coupling. Objective: to develop an electrodynamic model of a plasma-controlled choke with a Bitter coil and a radial pulse plasma system that controls an inductive element that implements the principles of magnetic energy accumulation. Methods used: mathematical analysis methods, constructive analysis, approximation theory, optimization methods, mathematical and computer modeling are used to solve the problem. Novelty: the novelty elements of the presented solution are the use of a method for controlling the inductance of a coil, which is an integral part of a magnetic storage generator, which, unlike the known ones, is based on a non-destructive plasma effect on an inductive element, which made it possible to abandon the use of explosion energy to deform a cylindrical conductive liner used in a second type magnetic storage generator (MCG-2). A method is proposed for a controlled change in the effective magnetic coupling and current distribution in the winding of an inductive element by introducing a conductive plasma into the gap between the winding and a conductive or semi-conducting shield. The use of an inductive element made according to the Bitter scheme is proposed and justified, unlike coils made by wire winding (MCG-1) or spiral milling (MCG-2), which made it possible to increase the mechanical and electrical strength of the coil, effectively dissipate heat, and counteract the pondemotor forces that occur when a pulse is passed. current through the coil. Practical significance: the use of the principles of magnetic cumulation with a multiple-acting inductive element makes it possible to synthesize the appearance of compact systems of remote electromagnetic action on electronic devices, commercial drones, communications equipment and electronic component base elements, with the aim of partially or completely disrupting the operability of the latter. It is shown that the developed method of controllably changing the effective magnetic coupling and current distribution in the winding through the introduction of a conductive plasma into the gap between the winding and a conductive or semi-conducting shield solves the problem of repeated use of a magnetic accumulator generator. Directions for further development of the work: the considered approach will be of interest to specialists in the field of radio engineering, when studying problems of applied electrodynamics, designing and optimizing systems for generating powerful electromagnetic pulses.
