The reflection model for propagation of solar cosmic rays

The principles of constructing the model are considered in this paper, together with the issues of its components and physical algorithm. The main emphasis is placed on the cause-and-effect relationships between the structure and dynamics of the solar and interplanetary media and the motion of solar cosmic ray particles. The specific features of the initial phase of motion of the particles after their acceleration in a solar flare are considered, as well as the subsequent phase of further particle propagation in the solar corona, and the phase of motion in the heliosphere. The processes of transport of charged particles in flare plasma ejections are considered in detail.
