Specific features of gas-discharge closing when a shock wave passes through the region of an applied electric field

The influence of a low-temperature plasma on the intensity and propagation rate of strong shock waves with a Mach number $\mathrm{M}$ = 6–8 has been analyzed. Propagation of a shock wave through the region of an electric field caused by voltage preliminarily fed to special electrodes built into the direct-channel walls where the shock wave passes has been considered in the current stage. It is found that the gas discharge in the region of an applied electric field is closed by an individual gas-discharge channel arising after the shock wave and propagating through the region of applied voltage at a lower speed compared with the shock wave. Neither the gas-discharge channel with a turbulent structure nor the region of homogeneous gas discharge arising after it affect the shock-wave structure and propagation rate.
