Numerical Simulations of the First Stage of Dynamics of a High-Speed Plasma Jet in Fluxus and North Star Active Geophysical Rocket Experiments

Time dependences of gasdynamic parameters of the high-speed aluminum plasma jets injected into the ionosphere at altitudes 140–300 km plasma jet explosive type generators (ETG) were obtained. The results of numeric simulations of the initial stage of jet dynamics agree with measurement data of gasdynamic and radiation characteristics of the plasma in laboratory and ionospheric experiments.
