“…The size of particles with nanometer range and their high resistance to agglomeration and sedimentation allowed to gain very stable aqueous suspensions of nanoparticles without the application of any surface-active stabilizing agents. It is necessary to note, that a range of technical solutions for similar kinds of discharges was recently proposed by Kusenov and Ryzhkov with coworkers [7][8][9][10][11][12][13][14][15][16]. In these studies, discharges of various configurations, also taking into account electric and magnetic fields, as well as different mechanisms of influence on the objects, were applied in plasma experiments.…”

In this study, polymer nanocomposite materials consisting of the copolymer of ethylene and vinyl acetate as a matrix and nanoparticles of zinc oxide as a filler have been obtained and examined by physicochemical and mechanical methods. Zinc oxide nanoparticles used in this study were fabricated using the plasma discharge under the effect of intensive ultrasonic cavitation. To ensure that resulting nanocomposites will acquire homogeneous distribution of filler nanoparticles, solution technology was utilized followed by the melt compounding technique, and also nanoparticles treated and non-treated with ultrasound were applied. The fabricated samples of nanocomposite material films were examined by X-ray phase analysis, then X-ray fluorescence analysis as well as scanning electron microscopy. The differences between the samples were demonstrated: when the nanoparticles without ultrasonic treatment were used, the particles were found to be more strongly aggregated within the bulk of the composite material and the average size of particles was visually larger in comparison to the sample filled with nanoparticles subjected to ultrasonic action. Finally, studies of the tensile strength and relative deformation of the samples were carried out. From the results of mechanical tests, it can be seen that, according to both studied parameters, there is an optimal concentration of ZnO nanoparticles. For tensile strength, the highest result was obtained at a concentration of nanoparticles of 3%, and for the relative elongation to rupture of the sample, the highest value was achieved at a concentration of nanoparticles of 2%.

“…However, it should be remembered that the MPC discharge in practice has a spatial 3D gas-dynamic structure. This structure approximately (there is a difference: there is a cumulation zone near the central electrode) corresponds to the flow structure in an underexpanded gas jet [119,120] flowing into a flooded space. For example, in a radially inhomogeneous plasma flow incident on a gas barrier, not a straight line arises, as was considered above (in the 1D approximation), but a conical magnetogasdynamic shock wave, in front of which the velocity component normal to the boundary with the gas is triggered and the pressure and plasma temperature increase.…”

“…To clarify this flow structure, a 2D physical and mathematical model was formulated in [119,120], and a numerical study of MPC discharges in gases was carried out for a wide range of changes in the main electrical parameters and characteristics of the surrounding gaseous medium. The features of radiation-plasmadynamic structures were revealed, and the behavior of the main parameters of the MPC-discharge plasma was described [119,120].…”

This paper provides an overview of modern research on magnetoplasma methods of influencing gas-dynamic and plasma flows. The main physical mechanisms that control the interaction of plasma discharges with gaseous moving media are indicated. The ways of organizing pulsed energy input, characteristic of plasma aerodynamics, are briefly described: linearly stabilized discharge, magnetoplasma compressor, capillary discharge, laser-microwave action, electron beam action, nanosecond surface barrier discharges, pulsed spark discharges, and nanosecond optical discharges. A description of the physical mechanism of heating the gas-plasma flow at high values of electric fields, which are realized in high-current and nanosecond (ultrafast heating) electric discharges, is performed. Methods for magnetoplasma control of the configuration and gas-dynamic characteristics of shock waves arising in front of promising and advanced aircraft (AA) are described. Approaches to the control of quasi-stationary separated flows, laminar–turbulent transitions, and static and dynamic separation of the boundary layer (for large PA angles of attack) are presented.

“…This means that the spacecraft can be moved between orbital positions more quickly, consuming less power and propellant for a given maneuver in space compared to a conventional unidirectional PS. One of the most promising technologies for thrusters that are capable of generating propulsion in multiple directions is electrodeless plasma thrusters [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Electrodeless plasma thrusters are based on sources that typically consist of a gas discharge chamber, a magnetic system, and an antenna with a high-frequency (HF), radiofrequency (RF), or microwave (mw) power supply.…”

Multidirectional plasma thrusters are of particular interest for dynamic space missions due to the adjustability of their integral characteristics. One type of multidirectional plasma thrusters is -directional, consisting of a symmetric electromagnetic system surrounding the gas discharge chamber, capable of generating a propulsion minimum in two directions. The experimental results of this study of the starting modes of a multidirectional plasma thruster utilizing krypton as propellant are reported. The thruster is placed in a vacuum chamber. The magnetic field strength is adjusted in the range of 35 to 400 G in peaks. The current of 13.56 MHz frequency applied to the antenna is regulated in the range of 0 to 25 A. The diameter of the orifices is varied in the range of 3 to 10 mm. In contrast to the unidirectional electrodeless plasma thruster, the radiofrequency breakdown threshold of the multidirectional plasma thruster decreases with increasing static magnetic field due to the symmetry of the magnetic system and the gas discharge chamber. The influence of the magnetic field on the radiofrequency breakdown threshold in the multidirectional plasma thruster is shown theoretically by the classical diffusion theory and ponderomotive effects, and discussed in the electron circulation hypothesis.
