When it is discharged to the intra-electrode gap, an expanding plasma channel is formed in a condensed environment, generating a IntroductionHigh-performance technological processes involving explosive energy conversion are widely used in various industries.

The article shows that the use of high-voltage electrical discharge installations, instead of traditional single-circuit capacitive double-circuit pulse generators, as well as control of the energy accumulated in them (by changing the capacitances and / or voltages of their charge) and the moment of energy input into the interelectrode gap filled with exothermic dispersed medium, allows to increase more than 1.5 times the energy efficiency of such facilities. This approach is especially effective when using exothermic medium containing aluminum with different dispersity as a fuel. In this case, the increase in the energy characteristics of the electric-discharge installations is ensured by increasing the duration of the exothermic processes. Moreover, one of the most important conditions for increasing the energy characteristics of such facilities is to maintain the pressure in the channel above the critical 1 / 3 2019 N 5 s12 value (~ 22.5 MPa), which is necessary for the flow of self-sustaining exothermic reactions.

The analysis and generalization of the results of studies of high-voltage electrochemical explosions (HVECHE) proceeding under various conditions, driven by special aspects and needs of the existing HVECHE based pulse-discharge technologies, was carried out. A methodology to calculate combined energy sources is proposed in relation to the needs of various discharge-pulse technologies using a high-voltage electrochemical explosion. Based on the analysis of the results of experimental studies, the advantage of using a high-voltage electrochemical explosion with a controlled input of electrical energy into the discharge channel was substantiated. An algorithm was developed to calculate the parameters of a combined electric-discharge source of a controlled HVECHE and the required mass of the exothermic composition which provides the energy characteristics specified by a specific discharge-pulse technology. The results of testing the developed calculation algorithm are presented confirming the possibility of its use for engineering calculations of combined power sources with a controlled input of electrical energy into the discharge channel.
