The article describes the study of the influence of the basic electrical and geometrical parameters of a pulsed plasma accelerator of the second stage hybrid pulse-periodic plasma system under the atmospheric pressure on the parameters of generated high-powered pulsed plasma formation. Investigation of the processes at the stage of pulsed high-current discharge was carried out on the basis of an electrodynamic approximation equation system. Numerical simulations are performed and characteristics of the plasma formation acceleration in the channel of the pulsed plasma accelerator are obtained. The relationship between the basic electrical and geometrical parameters of the pulsed plasma accelerator and the speed of the plasma formation is shown. The basic guidelines for choosing a scheme of the capacitive storage for the pulsed plasma accelerator are defined. It is shown that for the double-stage pulse-periodic plasma system under the atmospheric pressure one or two-circuits LC capacitive storage is optimal. The main parameters of the developed technological systems, ensuring generating plasma formations with the speed of 5-6 km/s, are determined.
