Mathematical model for large space structure is obtained on the basis of the new theory on deformable body motion; numerical and analytical method oriented on solution of equations of such model is developed. Effective procedure for calculating frequencies, modes and decrements of own oscillations of large spaced structures is developed to use in analysis of off-optimum situations. Formation of working surface large-sized guy reflector is studied. Methods of decrease in solar radiation pressure effects on orientation of high-length structure and structural configuration of devices realizing these methods are developed. Problems on dynamics of off-optimum situations for spacecraft with large-sized attached units under change in numbers of degrees of system freedom are invest Product Description popup.authors popup.nrat_date 2020-04-02 Close
