摘要：

The article presents the results of a 3D numerical simulation of the dynamics of high-speed aluminum plasma jets during their injection into a highly rarefied Earth's ionosphere, which can be considered a vacuum. The standard hydrodynamic approach is modified for taking into account the regime of supersonic injection of plasma into a vacuum. Scenarios of single and opposite injections are considered. The gas-dynamic parameters of plasma formations and their optical characteristics, obtained using standard and modified approaches, are determined.
