Mishchenko O. Methodological support for the design of electrodynamic space tethered systems

The thesis is devoted to the development of theoretical bases of making of passive electrodynamic space tethered system for deorbit of space debris objects from low near- Earth orbits by determining the basic laws of the system motion taking into account change of environment parameters. A mathematical model of the interaction of a passive electrodynamic space tethered system with the near-Earth environment has been developed, which provides analytical research on dynamics of the system and allows computation the values of the key design parameters of the system. A method for determining the critical parameters of a passive electrodynamic space tethered system taking into account different temperature modes of operation has been developed. The classifier of electrodynamic space tether system constructive schemes has been developed. A mathematical model of system dynamics has been developed, which allow computation the orbital and relative motion of the system taking into account the variability of the moment of ampere forces during orbital motion. An algorithm for computation the deorbit time for space objects depending on the space object mass, tether parameters and parameters of the initial orbit has been developed. The scopes of effective applying of passive electrodynamic space tethered systems as deorbit systems are determined. Methods and information technologies for selecting design parameters of the passive electrodynamic space tethered system have been developed.
