Abstract

The problem of modeling the injection of an aluminum jet of a plasma generator into the upper atmosphere during an Active Geophysical experiment is considered. The high-speed jet is a calibrated source of exposure. The gas-dynamic parameters of the jet are calculated. It is shown that in a rapidly expanding jet a violation of thermodynamic equilibrium occurs, causing to "freezing" of the ionic composition. The plasma jet interacts with the atmosphere and the geomagnetic field, causing the glow, the formation of a "diamagnetic cavity", and the generation of electromagnetic waves.
