Abstract

The traditional simulation model of sulfur hexafluoride ionosphere release is a simple point-source model and the simulation precision is not high. The three-dimensional refined simulation model of rocket SF6 release is established in this paper, in which the rocket pose and velocity, gas injection velocity and flow, and wind velocity are all taken into account in the diffusion equation. Meanwhile, the influences of geomagnetic inclination and the field diffusion on artificial disturbance form are considered in the plasma diffusion equation, and the two-dimensional plasma diffusion equation is extended to three-dimensional case. The ray tracing method is used to study the influence of ionospheric artificial disturbance on the short wave propagation path. The research results of the ionosphere kinetics process, ionospheric uneven body generation mechanism and evolution are of great significance.
