Реферат: eng: This work is devoted to the research of thermal deformation of segments in a parabolic reflector mirror in connection with the limitations determined by the radio frequency range of antenna operation. The thermal deformation analysis is performed based on the results of a numerical solution of the coupled problem of stationary thermal conductivity under conditions of radiation-convective heat transfer and thermoelasticity. A comparative analysis of five form factors of mirror segments was performed, which allowed choosing its preferred configuration. © Published under licence by IOP Publishing Ltd.
